Rod Tehrani: A Technical Advancement

By James Florence, Diamond Certified Resource Reporter

CONCORD — After eight years of working construction, Rod Tehrani felt it was time to advance to something a little more technical. “I decided to look into plumbing,” he relates. “At first, it was a lot more grunt work than technical, but that changed with time. The more I learned about the intricate aspects of the profession, the more I enjoyed it. Eventually, I got hired by the county as a crew leader for underground pipe replacement projects. In 2002, I started my own plumbing business, and it has been growing ever since.”

Today, as owner of Absolute Plumbing and Drain, Rod says his favorite part of his job is the daily challenges. “Every day brings new situations and new problems to solve. Even if the job is basically the same, the unique situation can differ significantly. I enjoy troubleshooting and finding solutions to challenging problems.”

Originally from Iran, Rod came to the United States in 1995 and currently resides in the East Bay Area. “Transitioning from life in Iran to life in the U.S. wasn’t exactly smooth,” he says. “I had a business degree, but back then it wasn’t recognized in the U.S., so I basically had to start over from scratch. What I appreciated most was the fact that I was accepted here, despite being from a totally different culture. I will always be appreciative of the people who accepted me for who I am and helped me get on my feet.”

In regard to his professional career, Rod espouses the importance of going the extra mile to ensure customer satisfaction. “I’m not worried about being the biggest or most profitable plumbing company; I’m more concerned about making our customers happy,” he affirms. “Sometimes that means going the extra mile. For example, I recently did a job where I was at the customers’ home until 9:30pm, just so I could make sure they had running water before I left. They couldn’t believe I was willing to stay that long, but they were very appreciative. Driving home, I was tired but happy. That’s the kind of feeling that’s more rewarding than money.”

When asked the first thing he’d do if he were to retire tomorrow, Rod says he’d take a cruise. “I work six days a week, so if I retired, I’d definitely take some time to relax. Maybe I’d go on a cruise to Costa Rica. Of course, I’d want to keep the business running with my guys, so I probably wouldn’t retire completely. Maybe I’d just transition into a less hands-on role.”

Daniel Gagne: Plumbing Pride

By James Florence, Diamond Certified Resource Reporter

NOVATO — When Daniel Gagne began his plumbing career, he had no idea of the level of success he’d one day attain. “My dad was a plumber, so I was introduced to the trade at a very young age,” he recounts. “After high school, I worked for the family business for a while, and after doing some traveling in my 20s, I ended up in Marin County, where I got a job with a local plumbing company. In 1996, my brother and I co-founded our own plumbing business, which focused on new construction and remodeling work in Marin, Napa, and Sonoma Counties.”

Three years into their joint venture, Daniel and his brother decided to reorient their focus toward service and repair; little did they know it would completely change the face of their business. “We joined a plumbing organization that specialized in training owners how to run profitable service and repair businesses,” he explains. “Through this organization, we were introduced to Benjamin Franklin Plumbing—a brand concept one could license that included a ready-made logo and everything. I liked the concept and decided to sign up. Once we began advertising as Benjamin Franklin Plumbing, things really took off. Our business exploded, and within three years, our staff had quadrupled in size. Ten years later, we have almost 100 employees and three different locations in the Bay Area.”

Today, Daniel looks back with pride upon his accomplishments of the past decade. “I never really intended to build such a big business—I was more interested in being able to write my own story. Still, I feel proud of the things we’ve accomplished as a company. We kind of pioneered, at least in the Sonoma-Marin area, the way plumbers are perceived by creating a cleaner, more professional presentation. I’m also proud of the fact that we provide our employees with good wages and full benefits so they can live comfortably and take care of their families.”

A resident of Fairfax (where he lives with his wife, Ann), Daniel spends his time outside of work engaged in a variety of active pastimes. “Ann and I love getting out into nature and going hiking at local national parks. We also love to travel—we take about three major trips each year. We were recently in Bali, where Ann hosted a retreat that she put together, and afterward we visited her daughter in New Zealand. We both have family outside of the country, so we have plenty of reasons to travel.”

In regard to a professional philosophy, Daniel believes that having happy employees translates to having happy customers. “We’ve discovered the best way to ensure our customers stay satisfied is to put our employees first,” he explains. “When your employees are happy, they’re more invested in doing good work and treating customers right, and when that happens, everyone wins.”

When asked the first thing he’d do if he were to retire tomorrow, Daniel says he’d embark on a Greener lifestyle. “I would probably buy a property somewhere with lots of nature around it, build a self-sustainable home and plant an organic garden. I think it would be a very peaceful and rewarding lifestyle—to live in harmony with the Earth.”

Ricardo Lopez: A Rewarding Career

By James Florence, Diamond Certified Resource Reporter

RICHMOND — Ricardo Lopez was initially drawn to the plumbing trade by the pay, but it wasn’t long before he discovered the true rewards his career provided. “I was told that plumbers made good money, so I decided to start an apprenticeship with a local company,” he remembers. “The pay was good, but what I really liked about the job was the opportunity to help people, especially elderly customers who are vulnerable to being taken advantage of. It felt very rewarding to be able to take care of people and provide an honest service. After five years working in the field, I decided to found my own business in 2002.”

Today, as owner of Superior Plumbing & Drain Cleaning Services, Ricardo says his first priority is providing top-notch customer service. “I personally train each of our employees in the way we present ourselves and serve our customers. To me, the most important thing is making sure every customer is satisfied, both with the work itself and the professionalism of our technicians.”

Originally from El Salvador, Ricardo resides today in Antioch with his wife, Fatima, and their two children. Outside of work, he spends his free time engaged in a variety of active pastimes. “My kids like the water, so we do a lot of swimming and boating at local lakes,” he says. “We also like to play basketball and soccer.” Additionally, Ricardo and his family make a point of traveling two to three times each year. “We regularly vacation at places like Cancun and Belize. Also, since my wife is from Mexico, we go to Guadalajara every January to see her family and take part in the holiday festivities.”

In regard to his professional career, Ricardo espouses the importance of taking care of people. “In addition to taking care of our clients, I believe in taking care of our employees,” he explains. “I try to make sure everyone who works for me is well-compensated and happy in their job. After all, when your employees are happy, they’re more likely to pass that on to customers in the form of good service, so it’s a great investment all in all.”

When asked the first thing he’d do if he were to retire tomorrow, Ricardo says he’d take an extended vacation. “I would take a month-long trip with my family, maybe to Cancun or my home country of El Salvador. It’d be nice to just take some time to relax and recuperate by the beach.”

Know What You Want
When Do You Want to Call in a Contra Costa County Sewer Line Contractor?

You may not initially know that your problem is severe enough to call in a sewer line contractor. You may be hoping that you’ve just got a temporary clog. But if the problem escalates or persists, you will want to call in someone who can give you a diagnosis.

As you prepare to call in a sewer line contractor in Contra Costa County, there are some questions to ask yourself. No plumbing crisis is fun, but you might be able to face it better if you have a list of questions prepared. That way, you know what you have to focus on at the time of the crisis.

The following list of questions might be helpful.

  1. Do I want a Diamond Certified sewer line repair company that is rated best in quality and backed by the Diamond Certified Guarantee?
  2. How long has the problem been happening?
  3. Is there a pattern of recurring behavior with the problem, or is this the first time?
  4. Do I know whether my house has cleanouts or not? And where they are located?
  5. Is the problem based around a single fixture, or are multiple fixtures involved? For example, is the toilet backing up into the tub?
  6. Are there external signs of a problem, such as toilet paper in the yard?
  7. Do I use the city sewer system or do I have a septic tank?
  8. Are there trees or bushes that are growing along where the sewer line runs?
  9. Is it important to me to save a tree that is affecting my sewer line?
  10. Are my sewer lines isolated or are they close to gas lines or clean water lines?

What To Ask In Person
Asking Your Contra Costa County Sewer Line Contractor Questions in Person

You are most likely to meet your Contra Costa County sewer line contractor in person when the company comes to prepare an estimate. Many situations are unique. Mostly likely the contractor will need to see your property and any landscaping to get a good idea of potential causes of the problem. Your contractor will have to get a good idea of the sewer pipe layout and where the city sewer hook-up might be.

It makes sense to expect a good sewer line contractor in Contra Costa County, including in Walnut Creek, Concord, Pittsburg, Antioch, Richmond, or Brentwood, to take a look before offering an estimate.

When the sewer line contractor comes, you may want to ask some questions so that you get a good idea of how the contractor decided on the recommendations made. Having questions prepared in advance can be helpful in the midst of a stressful situation. Some questions like the following might make sense.


  1. Do you think you can perform trenchless replacement here? Or will a trench be required?
  2. Can you help me locate a cleanout?
  3. If we cannot find a cleanout, or I know I don’t have one, what fixture or other option will you use to access the sewer line?
  4. How close is my property to the city sewer hook-up? Will there be extra costs to connect to it?
  5. Do you see any problems with the current landscaping and the run of the sewer line? Do I need to consider removing brush or trees?
  6. How long do you think the job will take?
  7. Can you access the site with whatever equipment you need to perform the repair?
  8. How quickly can you start the job?
  9. If you are making a repair, not a replacement, will that area of the pipe be more vulnerable to future damage?
  10. Why are you recommending a replacement – can you just repair the portion of the sewer line that is damaged?

  • What To Ask References
    Questions for Previous Clients of Contra Costa County Sewer Line Repair Companies

    It’s best to choose a Diamond Certified sewer line contractor because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a sewer line contractor in Contra Costa County and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies.

    And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified sewer line contractor within reach, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your sewer line contractor. Keep in mind, though, that references provided to you by the sewer line contractor are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process.

    That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

    If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

    1. Did you have an open trench repair? Or did you use trenchless repair methods?
    2. How long has the sewer line repair or sewer line replacement been installed? Have you noticed any problems after the service visit?
    3. Did your contractor clearly explain why a replacement was required instead of a repair?
    4. What was the issue? How could you tell you needed a sewer line repair or replacement as opposed to removing a one-time block?
    5. Did you have problems with tree or brush roots? Did you remove the tree or brush as part of the solution, or are they still in place? If they are in place, are they likely to cause further problems?
    6. For any trenches or openings made on your property – were they properly filled after the job was finished? Were you satisfied with the state your property was left in?
    7. I don’t have a cleanout. Do you? If not, how was your sewer line accessed?
    8. Did the sewer line contractor work with the proper authorities to help you get any required permits?
    9. Did the sewer line contractor explain the materials being used, how long they should last, their environmental impact?
    10. Were you satisfied with the sewer line contractor’s work? Why or why not?

  • Review Your Options

    The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

    4. Is the sewer line contractor concerned with first correctly identifying the source of the problem before making recommendations?
    5. Is the sewer line contractor licensed by the state of California?
    6. Does the sewer line contractor find it important to work within code, using the proper materials?

  • How To Work With
    Before You Decide to Hire a Contra Costa County Sewer Line Contractor

    When you are pondering which Contra Costa County sewer line contractor to hire, be sure to do a little background investigation. Ask several contractors for written estimates. Don’t work with a contractor who won’t give you a written estimate.

    Look for contractors who show expertise and experience in working with sewer lines. Be sure the contractor is licensed. You can check that the license is current and that there are no complaints against it by going to the Contractors State License Board (CSLB) website.

    Find a physical address for the company and verify that it is real. It’s best to have several ways to contact a firm, and a brick and mortar presence can always be a last resort. If a contractor is only available by mobile phone, carefully consider how valid it may or may not be.

    Once You’ve Found Your Contra Costa County Sewer Line Contractor
    Take the time to cover all the bases with your Contra Costa County sewer line contractor. Be sure you ask about how the problem was diagnosed. A camera will most often be used to pinpoint the exact problem – you should not accept “guesstimates.” A proper contractor will take the time to find the problem. If the sewer line contractor suggests several steps – such as jet cleaning the pipe before the camera is used, always ask whether there are additional charges.

    Ask your Contra Costa County sewer line contractor if the company needs to dig a trench or if other options are open. If you want trenchless techniques, ask about them. If a trench is required, be sure your sewer line contractor clearly explains why a trench is required. Be sure to agree with your sewer line contractor about the expected state of your property after the repair – holes and trenches filled and level, for example.

    Make sure you understand what part of replacing the landscaping, if any, the sewer line contractor will perform. They probably will only be responsible for filling the trenches, but make sure you understand what they will and won’t do.

    Are there trees or shrubs running along your sewer line? Do you want to save the trees or shrubs? Can the sewer line contractor remove roots that are causing the problem, for example, without killing the tree? Do the trees or brush have to be removed to prevent further recurrences of the problem?

    Be clear about whether you want to save a tree or whether you are fine with it being removed. In some cases, you may have no options. Again, it’s important to discuss your expectations with your Contra Costa County sewer line contractor, whether you live in Walnut Creek, Concord, Richmond, Pittsburg, Antioch, El Cerrito, West Pittsburg, San Ramon, or Brentwood.

    Making the Job Easier for Your Contra Costa County Sewer Line Contractor
    You can make the job go more easily for your Contra Costa County sewer line contractor. If possible, know the location of your cleanout or cleanouts. If you can, determine that gas pipes and clean water lines are not placed near your sewer line. If the sewer line contractor will be working from a cleanout in the house, clear the path to it. If there are weeds obstructing an outdoor cleanout, try to clear them before the job begins.

    Make sure your expectations are included in the written estimate and contract. For example, if you expect trees to be saved, get it in writing. Get as much as you can in writing before the job starts – don’t come up with new issues in the middle of the project.

    Be available to answer your sewer line contractor’s questions. If unexpected things crop up, the sewer line contractor will need to be able to get in touch with you to make decisions.

  • Be a Good Customer
    How Can You Be a Good Sewer Line Contractor Customer?

    It’s the sewer line contractor’s responsibility put in quality sewer lines using the best possible installation techniques. But you play a big part in the success of your sewer line contractor, too.

    Here are a few simple steps you can take to be a good customer when hiring a Contra Costa County sewer line contractor.

    Be clear and upfront with the sewer line contractor. Let them know what you want from your sewer line contractor, the long-term outcome you’re expecting and specific ways they can satisfy your expectations.

    1. Remember, a friendly smile goes a long way!
    2. Before you hire a sewer line contractor in Contra Costa County, restate your expectations and goals, and reiterate to the sewer line contractor’s representative your understanding of the agreement. Most problems with local sewer line contractors occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.
    3. Ask your sewer line contractor if you should call to check on the progress or if he will call you with updates.
    4. Be sure your service representative has a phone number where they can reach you at all times while they’re working on the sewer line. The work will move along more smoothly if your sewer line contractor can reach you for any necessary updates, questions or work authorizations.
    5. When your contractor contacts you, return calls promptly to keep the sewer line contractor on schedule.
    6. Pay for the sewer line contractor’s work promptly.

    Why would you want to be a good customer? Sewer line contractors in Contra Costa County appreciate customers who are straightforward, honest and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship. Things may very well go smoother and any problems may be more easily resolved.

Check The Work
Verify Your Contra Costa County Sewer Line Contractor’s Work Against the Estimate and Invoice

A written estimate and contract should outline precisely what is happening on your property. Get the estimate and contract written in as much detail as possible. For example: open two holes, insert PVC liner, steam liner into place, remove bladder after liner is cured, is better than: install trenchless replacement.

When there is more detail, you can be sure of what is covered and what is not. You are then in a better position to check off what has been completed and what has not been. Don’t be shy about examining the work, if you want to.

Sewer line inspection cameras should allow you to see into the pipe to be sure that it is no longer blocked, or that the new liner runs its complete length. Always be sure the written contract covers how your property is to be restored after the repair – for example, all holes refilled and leveled. Make sure that your property is in the state you expected it to left in.

Written Warranties
Asking Your Contra Costa County Sewer Line Contractor for Warranties

The majority of plumbers and sewer line contractors provide warranties on the repairs they carry out. Read the warranty closely to see what it covers and what it does not. For example, if the ground freezes and the sewer line is damaged as a result, will that be covered or is that considered outside the contractor’s control?

Such conditions are often spelled out in the warranty – sometimes in blanket language. Be sure you understand what the blanket language is covering and what it is not.

Top 10 Requests
Popular Sewer Line Service Requests in the Contra Costa Area

Sewer line contractors often receive requests when homeowners are at their most frantic. The best sewer line contractors in Contra Costa County, whether in Walnut Creek, Concord, Antioch, Richmond, Pittsburg, Brentwood, Martinez, or Pleasant Hill, respond promptly and with expertise. They even offer services designed to help prevent emergencies.

Sewage Smell Abatement
Unfortunately, one of the indicators of a broken sewer line can be a smell of sewage. Sewer line contractors and plumbers should come and assess the smell and the pipes before drawing up a contract to address the problem.

Waste in Bathtub
Sometimes, attempting to clear a toilet drain results in waste backing up into the bathtub. This is a sign that you need to have your sewer lines checked.

Hydro-jetting is a technique used to clear pipelines of grease or other debris that can build up over time. Some contractors recommend that hydro-jetting be an annual process so that the pipes remain clear, especially on rentals and commercial properties.

Toilet Flush Properly
When the toilet will not flush properly, it can be a sign of greater problems. Of course, sometimes a simple plunger can remove a temporary blockage. But if your toilet continues to backup frequently or you cannot plunge the matter away, you may need a sewer line repair or replacement.

Sewer Line Repair
Not every problem is going to require a replacement of the entire sewer line. Sometimes a pipe is cracked or broken in such a way that only a small portion of the pipe needs to be replaced. A sewer line repair is warranted in such cases.

Sewer Line Replacement
Sometimes the damage to the sewer line is so comprehensive that the whole line must be replaced. If you have old, clay-based piping, it will be replaced, not repaired, since the clay piping does not meet the current standards. When evaluating repair vs. replacement, keep in mind that having to place multiple patches on the pipe over time can add up.

Replace Septic System
If you have a septic tank, you are responsible for emptying it. Some prefer to not have that burden. In cases where the municipal system is available, you can have your septic tank replaced with a sewer line that connects you to the municipal sewer system and frees you from one burden.

Slow Draining Toilet or Tub
If the water drains slowly from your toilet or tub, there may be a blockage or damage to the sewer line. Of course, the first step is to try to remove any blockage. If that does not solve the problem, check for breaks and breaches in the sewer line.

Tree Roots
Trees seek out water and are attracted to your sewer pipe. On occasion, tree roots can penetrate the pipes. The root balls can create blockages that must be removed. The pipes must then be repaired or replaced.

Video Inspection
Cameras exist that allow your plumber or contractor to look down your sewer line for breaks obstructions. If other measures are failing, you might want to have someone examine your pipes with a camera so that you can identify the problem.

Q: Do I have to dig up my entire yard to fix my sewer line?
A: There are techniques available today that will help you get a sewer line replacement or sewer line repair without digging up your yard. You can get your pipes relined, which creates a new pipe within the existing pipe. The new pipe lining is pulled through the existing pipe, then heated so that it creates a solid, resistant pipe. Another option is to use pipe bursting in which a bursting head breaks up the existing pipe in the ground and pulls a new pipe along behind itself.

Q: How much of the sewer line am I responsible for?
A: The homeowner is generally responsible for the sewer line that runs from the house to the edge of the sidewalk closest to house. Once the line reaches city property, like the sidewalk, it becomes the city’s responsibility, in most cases. You should check with your locality about the specifics of where the municipal responsibility picks up. Anytime your sewer line repair or replacement looks like it is hitting the sidewalk, you should call the municipal government to be sure where your responsibility stops.

Q: What makes a sewer line need repair?
A: Sewer lines get blocked and broken because of many reasons. If you drop things down the drain, they can form the basis of a clog that will not allow water and waste to pass. In addition, pipes can crack, especially old fashioned clay pipes, so clay pipes are no longer allowed. Tree or brush roots may get into the pipe and form the basis of the blockage. Or settlement of the land over time, or swelling or contracting of the pipes due to freezing or thawing may weaken the pipes and cause them to sag or crack.

Q: Should I trust someone who says he or she has “a good idea” of where a problem is occurring?
A: Plumbers and sewer line contractors today have very sophisticated technology, including cameras that can be used to view the inside of the pipes. Your sewer line contractor should use the camera to determine exactly where the problem is before starting to dig or repair the issue.

Q: Do I need a licensed contractor?
A: Yes, in California, you should get a licensed sewer line contractor to perform work on your sewer line. When you look for your contractor, you will see firms advertising as either sewer line contractors or as plumbers. Just make sure the firm has experience in working with sewer lines, and that they are licensed by the state of California – the license number should appear in their advertising – and that they are bonded and have worker’s compensation insurance for their employees.

Q: Do I need a permit for my sewer line repair or sewer line replacement?
A: In most cases, yes, you will need a permit for your sewer line repair or replacement. Your contractor should be able to help you get this permit. Be sure to ask about whether or not the firm helps with obtaining the permit.

Q: When do I need to do more than clear a block?
A: You can start to resolve wastewater problems by trying to clear a drain. Often, homeowners or plumbers will begin by trying to snake a pipe, or use other methods to clear it. If you cannot clear the blockage and get the fixture running again, or if the blockage recurs frequently, it may be time to check the sewer line. If you have sewage showing up outside, a bad sewage smell, or other obvious signs, it may be time to replace the sewer line.

Q: What’s the different between a sewage line and a septic tank?
A: A sewage line connects the individual house to a municipal wastewater system. The wastewater is carried through pipes to facilities that can process the wastewater. With a septic tank, the waste is piped from the house into a tank on the property and stored. Once the tank is full, it must be pumped dry before more can be added. If the municipality’s sewage system reaches the house with a septic tank, the house can be converted from a septic tank to the sewage system. Some sewer line contractors and plumbers specialize in these conversions.

Q: What is the environmental impact of using pipe relining?
A: The material used to reline pipes is epoxy-based and safe for the environment.
