Myles O’Dwyer: Pipe Guru

By James Florence, Diamond Certified Resource Reporter

LARKSPUR – It might come as a surprise to learn that Myles O’Dwyer’s turn as president of a plumbing service company was preceded by an extensive career in commercial finance. On the other hand, it explains a lot about the thriving success of his business. As Myles tells it, his newfound venture came as the result of a failed business merger. “I was in the process of negotiating a merger between a plumbing parts supplier and a service company, with a plan to combine them into a national franchise. When the parts supplier backed out, I went to work for the service company with an aim to improve its financial performance.” Benefitting from his business acumen, Pipe Spy expanded its operations to Marin in 2007, where Myles continues to run things today.

Originally from the Bay Area, Myles’ career in finance took him all over the United States, from Chicago to Connecticut to Los Angeles, before an opportunity arose for him to return to his native environment. Having spent several winters on the East Coast, Myles attests to a renewed appreciation for the temperate North Bay climate. “We still have our seasons, but it’s nothing like back east,” he affirms. “When I lived in Connecticut, the trees would lose all their leaves and just look like dead sticks for five months. It was depressing.”

While his career keeps him busy, Myles finds time to enjoy a variety of hobbies outside of work, from weekly basketball games to renovating classic cars and motorcycles, including his father’s 1934 Ford pickup. He also likes to keep up with his four daughters, all of whom are variously situated along the West Coast. “My oldest daughter is a kindergarten teacher in Seattle, Washington, my second-oldest is a chef in San Francisco, and I have a set of twins who are in college,” he proudly says. Myles also enjoys going out to support the football team of his Berkeley alma mater, the Cal Bears.

When asked what his future retirement might look like, the ever-ambitious Myles intimates that it’ll likely be the start of another enterprise altogether. “One of the things I’ve always wanted to do is get my PhD, so I’ll probably do that after I retire,” he says. “I haven’t decided whether to focus on business ethics or political science—I guess I’ll cross that bridge when I come to it!”

Ask Me Anything!

Q: Do you have a favorite movie?
A: I remember the best double feature I ever went to: “Patton” and “MASH.”

Q: What kind of books do you like to read?
A: I like mysteries that have some kind of historical element to them, like The Da Vinci Code.

Q: Beatles or Rolling Stones?
A: Beatles—but actually, the Beach Boys are the best!

Q: Who makes you laugh?
A: Richard Pryor, Steve Martin and Robin Williams.

Q: What’s your favorite snack?
A: Oatmeal cookies.

Q: What was your favorite Halloween costume as a child?
A: Every year I wore the same costume: the classic bed sheet ghost. It was very effective.

Know What You Want
Do You Think You Need a Sonoma County Sewer Line Contractor?

As you prepare to call in a sewer line contractor in Sonoma County, whether in Windsor, Santa Rosa, Healdsburg, Petaluma, Rohnert Park, Sebastopol, Cloverdale, Sonoma, Cotati, or Guerneville, there are some things you can ask yourself to get a better understanding of the situation. No plumbing crisis is fun, but you might be able to face it better if you have a list of questions already ready. That way, you know what you have to focus on at the time of the crisis. The following list of questions might be helpful.

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

What To Ask In Person
Questions to Ask Sonoma County Sewer Line Contractors in Person

You and your Sonoma County sewer line contractor will probably meet in person when a representative visits you to give you an estimate. The sewer line contractor will need to see your property and any landscaping to get an initial idea of potential causes of the problem.

Your sewer line repair contractor will have to get a good idea of the sewer pipe layout and where the city sewer hook-up is. It makes sense to expect a good sewer line contractor in Sonoma County, whether in Windsor, Santa Rosa, Healdsburg, Rohnert Park, Petaluma, Guerneville, or Sebastopol, to take a good before offering an estimate.

When the sewer line contractor arrives, you may want to ask some questions so that you get a good idea of how the contractor came to the recommendations he or she made. Having questions written down in advance can be helpful in the midst of a stressful situation.

Asking questions like the following might be useful:

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

  • What To Ask References
    Questions for References of Sonoma County Sewer Line Contractors

    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 Sonoma 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. Were you satisfied with the sewer line contractor’s work? Why or why not?
    2. Did you have an open trench repair? Or did you use trenchless repair methods?
    3. Did the sewer line contractor explain the materials being used, how long they should last, their environmental impact?
    4. I don’t have a cleanout. Do you? If not, how was your sewer line accessed?
    5. 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?
    6. 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?
    7. How long has the sewer line repair or sewer line replacement been installed? Have you noticed any problems after the service visit?
    8. Did your contractor clearly explain why a replacement was required instead of a repair?
    9. What was the issue? How could you tell you needed a sewer line repair or replacement as opposed to removing a one-time block?
    10. Did the sewer line contractor work with the proper authorities to help you get any required permits?

  • How To Work With
    Making the Final Decision for a Sonoma County Sewer Line Contractor

    You make the final choice for your Sonoma County sewer line contractor, perform a small amount of preparation. Ask at least two contractors for written estimates. Never consider working with a contractor who won’t write up an estimate. Look for contractors who show expertise and have some years of experience in working with sewer lines.

    Be sure the contractor’s license is not expired. You can verify the status of the license, including whether there are any complaints against it, by going to the Contractors State License Board (CSLB) website. See if the company has a physical address and verify that it is real. It’s always good to have multiple ways to contact a firm, and a brick and mortar presence can always be your last resort. If a contractor is only available by cell phone, carefully consider how legitimate the company may or may not be.

    Now that Your Sonoma County Sewer Line Contractor is Selected
    Make sure you know how your sewer line contractor reached the recommendation he or she made. The best case is for a camera to be used to pinpoint the exact problem. Don’t sign a contract based solely on “guesstimates.” A proper contractor will take the time to locate the specific problem. If the sewer line contractor suggests that the pipes be jet cleaned before the camera is used, ask whether additional charges apply.

    Your Sonoma County sewer line contractor should be able to outline the various methods that could be used to resolve your plumbing issues. If you want to use trenchless techniques, ask about them. If your circumstances demand a trench, ask your sewer line contractor to clearly explain why the trench is the only method that will work. Be sure to agree with your sewer line contractor about the state your property should be restored to after the repair. Do you want holes and trenches filled and leveled?

    Make sure you understand whether the sewer line contractor will replace any landscaping removed during the repair or not. Most often, the sewer line contractor will only be responsible for filling the trenches or holes, but make sure you understand what the contractor will and won’t do.

    If trees and shrubs are the problem, they are probably worth a conversation. Do you want to retain the trees or shrubs? Is it possible for the sewer line contractor to remove roots that are causing the problem without killing the tree? Do the trees or shrubs have to be removed completely to prevent further recurrences of the problem?

    Be clear about whether you want to keep the trees or whether you have no qualms about their being torn out. In some cases, you may have no alternative other than to remove the tree. Above all, it’s important to discuss your expectations with your Sonoma County sewer line contractor, whether you live in Windsor, Santa Rosa, Petaluma, Healdsburg, Rohnert Park, Sonoma, or Sebastopol.

    Smoothly Out the Job Easier for Your Sonoma County Sewer Line Contractor
    Your Sonoma County sewer line contractor appreciates contributions you can make to make the project go more smoothly. Search out your cleanout or cleanouts. If you can, determine where the gas pipes and clean water lines are so that you can be sure they are not placed near or on top of your sewer line. If the sewer line contractor will be working from a cleanout that is in the house, make it as easy as possible to access that cleanout. If there are weeds obstructing an outdoor cleanout, try to remove them before the job begins.

    Use your written estimate and contract to be sure all your bases and expectations are covered. 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. Avoid coming up with new issues in the middle of the project. You’ll bump into enough unexpected issues as the job progresses, so be sure to resolve the known issues before you start. 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 Sonoma 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.
    • Remember, a friendly smile goes a long way!
    • Before you hire a sewer line contractor in Sonoma 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.
    • Ask your sewer line contractor if you should call to check on the progress or if he will call you with updates.
    • 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.
    • When your contractor contacts you, return calls promptly to keep the sewer line contractor on schedule.
    • Pay for the sewer line contractor’s work promptly.

    Why would you want to be a good customer? Sewer line contractors in Sonoma 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
Your Estimate and Contract are Good Tools for Checking Your Sonoma County Sewer Line Contractor's Work

Your Sonoma County sewer line contractor needs to give you detailed estimates and contracts. Get the estimate and contract written in as much significant detail as possible. For example a specification like: “open two holes, insert PVC liner, steam liner into place, remove bladder after liner is cured,” is better than one that simply reads: “install trenchless replacement.” The detail ensures you know what is covered and what is not. You are in a much better position to evaluate what has been completed and what has yet to be completed.

Feel free to examine the completed work, if that’s what you want to do. The company should have cameras that allow you to see into the pipe to be sure that it isn’t blocked, or that the new liner runs the complete length of the pipe. Make 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
Getting Your Warranty From a Sonoma County Sewer Line Contractor

Most sewer line contractors or plumbers offer a warranty of sorts. Ask for about a warranty if you are not automatically offered one. Examine the warranty closely to see what it covers and what it excludes. For example, if the ground freezes and damages the sewer line as a result of that freezing – will repairing the pipe be covered or is that circumstance considered to be outside the contractor’s control?

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

Top 10 Requests
Top Service Requests for Sonoma County Sewer Line Contractors

Get the help you need when a sewer breaks. The best sewer line contractors in Sonoma County, including those in larger cities such as Windsor, Santa Rosa, Rohnert Park, Petaluma, Healdsburg, Sebastopol, Cotati, or Guerneville, respond promptly and with expertise. They even offer services designed to help prevent emergencies.

Hydro-Jetting Services
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.

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.

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.

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.

Proper Toilet Flush
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.

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.

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.

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.

Frequently Asked Questions
FAQs for Sewer Line Repair and Replacement Companies

Q: Why choose a Diamond Certified sewer line contractor?
A: Diamond Certified helps you choose a sewer line contractor with confidence by offering a list of top rated local companies that have passed the country’s most in-depth rating process. Only sewer line contractors rated Highest in Quality and Helpful Expertise® earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee, so you’ll feel confident choosing a Diamond Certified sewer line contractor.

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.
