DIAMOND CERTIFIED EXPERT CONTRIBUTORS IN THE San Francisco – Plumbing CATEGORY

Mostafa Sowadah: One Source for Success

By James Florence, Diamond Certified Resource Reporter

SAN FRANCISCO — Following high school, Mostafa Sowadah knew he wanted to get into a trade—it was just a matter of deciding which one to pursue. “When I was enrolling in trade school, I had the choice of going into automotive, plumbing or HVAC,” he says. “Based on what I saw most people signing up for, it seemed that plumbing was the least popular option. However, I’d always heard good things about plumbing, so I decided to give it a shot.” After finishing his two-year program at WyoTech-Fremont, Mostafa did a four-year apprenticeship with a local plumbing company and then worked another three years as an employee before starting his own business in 2013.

Today, as owner of One Source Plumbing and Rooter, Inc., Mostafa says his favorite part of his job is building relationships of trust with his customers. “The first time you do a job for a customer, they aren’t totally sure if they can trust you. However, when they call you again a couple of years later, it shows there’s trust because the first job didn’t fail. That’s a great feeling.”

A lifetime resident of San Francisco, Mostafa expresses his appreciation for the character of life and work in the City by the Bay. “There are three things I like about San Francisco: the diversity, as there are people here from all over the world; the nice weather, which is good for plumbers because we do a lot of work outside; and the simple fact that I’ve lived here my whole life and it’s home.”

When asked about a professional philosophy, Mostafa offers a simple guideline for ensuring quality workmanship. “On every job, I have the mindset that I want my work to outlive me,” he explains. “When your main goal is to build something to last as long as possible, you’re going to do a better job than if you’re just looking to make money. The great thing is that when you build something to last, your customers are going to be happy and bring you more business, so the money will follow naturally.”

When asked the first thing he’d do if he were to retire tomorrow, Mostafa says he wouldn’t. “That’s a tough one, because I’ve sort of become programmed to stay busy. I think it started during my apprenticeship, where for four years I worked six days a week, with no holidays or vacations. As soon as I finished it, I took a week-long vacation; the first two days were nice, but by the third day I was kind of bored. That’s why I’m not sure I could retire—I like being busy and I enjoy my work, so the idea of retirement just doesn’t appeal much to me.”

Anthony Abbas: Accelerated Advancement

By James Florence, Diamond Certified Resource Reporter

SAN BRUNO — Anthony Abbas didn’t have a predisposition to plumbing when he entered the field, but that didn’t stop him from advancing faster than most. “I didn’t have any family members in the business or anything—I just started from scratch,” he says. “I began working for a local company, and within two years I obtained my license and started my own business.” Today, as owner of In & Out Plumbing, Anthony says he enjoys the versatile character of his chosen profession. “I like meeting and interacting with different people every day, as well as working with my hands. There are a lot of aspects to the job, so it never gets boring.”

As a resident of San Bruno, Anthony expresses his appreciation for his adopted hometown. “Everything is close by and my customers all live in the area,” he says. “We also have good schools and it’s very safe. Overall, it’s a nice place to live.”

Outside of work, Anthony devotes much of his time to physical fitness. “I’m an avid bodybuilder,” he affirms. “I used to do it competitively, and it’s something I’ve continued to stay involved with through the years. Between that and my daily work, I’m able to keep in shape.” Anthony says his passion for physical fitness is shared by his family. “My wife and kids also like working out, and my kids both played sports in high school, so the whole family is pretty athletic.” Additionally, Anthony enjoys exploring San Francisco, trying new restaurants and going on the occasional family road trip.

In his life and career, Anthony espouses the importance of putting forth his best effort. “I believe that if you’re going to do something, you ought to do it right,” he says. “The reason I’ve been successful is because whenever I do something, I do it to the best of my ability. I take pride in my work, and the effort I put in pays off every time.”

  • Do I want a Diamond Certified plumbing contractor that is rated highest in quality and backed by the Diamond Certified Guarantee?
  • What do I need from a local plumbing company (emergency plumbing repairs, plumbing services, new construction plumbing installation, new plumbing fixtures, etc.)?
  • What is my budget for the plumbing work or plumbing repairs?
  • If I need new plumbing fixtures, is there a specific style or brands I’m looking for (i.e. Toto plumbing fixtures, Kohler plumbing products, modern plumbing supplies, traditional fixtures, contemporary plumbing fixtures)?

  • How much time will the job take, from ordering the new plumbing fixtures through installation?
  • Will I be able to stay in my home during the plumbing work? Or will the water be shut off for too long to comfortably stay?
  • If applicable, do you have energy-saving plumbing fixtures and other plumbing products that can save me money in the long run?
  • Have you completed any similar recent projects in my area of San Francisco?
  • Do you have a list of customer references I can call?
  • How do you finish the plumbing installations? Will you leave my bathroom or kitchen in the same or better condition than it was in before you started the work?

  • What To Ask References
    Interview Previous Customers About Their Experiences with San Francisco Plumbers

    It’s best to choose a Diamond Certified plumbers because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a plumbing contractor in San Francisco 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 plumbing company 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 plumber. Keep in mind, though, that references from your plumbing 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 plumbing 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 plumbing repair/plumbing installation/plumbing service from _(company name)_?
    2. What was the type and scope of job they did for you (emergency plumbing repairs, new construction plumbing installation, fixture replacement, etc.)?
    3. Did they complete the work on time?
    4. Did the plumbers keep you up-to-date on the status of your plumbing project?
    5. Were there unexpected costs associated with your plumbing repairs or plumbing installation? If so, what were they for and were they avoidable?
    6. Did the plumbing contractors show up on time?
    7. Did they clean up after finishing the plumbing work?
    8. When you need new fixtures or plumbing repairs in the future, would you use this plumber again?
    9. Would you recommend their services to friends and family?

  • How To Work With
    Encourage the Best Plumbers in San Francisco to Bid on Your Job

    Some homeowners have found it’s a valuable resource to hire a plumber for a smaller project before signing a contract for a major plumbing repair or installation. Others like having a working relationship with a local plumbing contractor because it gives them the confidence to know who to call in a plumbing emergency and who they can trust for a large plumbing job.

    It’s important to know that some good plumbing contractors in San Francisco are choosy about which jobs they accept. This is because bids take time and expense to prepare, and some of these local plumbers have been taken advantage of by unreasonable homeowners. How can you encourage the best plumbing contractors to be interested in your job?

    • Show the plumbers you interview that you’re interested in a good value, not just the lowest bid. Oftentimes, the first questions plumbing contractors hear from potential customers is about the cost of a job. You can show them you know what’s really important in a plumbing installation and repair by asking about quality products, knowledgeable installation and overall value.
    • Be honest if you’re interviewing a few plumbers, but assure each that you’re accepting bids from a few select companies, not dozens.
    • Interview and hire local plumbing companies in San Francisco including the larger neighborhoods of Sunset District, Tenderloin, Richmond District, Mission District and Bernal Heights. Most plumbers like to work in the local area, since it allows them to provide more timely service. It also helps you weed out less reliable plumbing contractors who travel long distances and install discounted products at a cut-rate that local contractors may not be able to compete with price-wise.
    • Be upfront about your needs and desires for your plumbing repairs or new plumbing installation. The more you share with your plumbing contractor, the easier it is for them to give you a reliable bid, the right plumbing services, and the follow-up service you need.

    Contracts that Protect You and Your Plumbing Contractor
    Congratulations! You’ve found a good plumbing company that meets all of your requirements. Whether you’ve chosen a plumber from the larger neighborhoods of Sunset District, Richmond District, Mission District, Tenderloin, Bernal Heights, Excelsior, Pacific Heights, Nob Hill, North Beach and Bayview District or a smaller town, now is the time to request a contract for the work desired.

    The contract should include in detail the scope of the plumbing project, any items or services that are excluded, payment terms, the exact plumbing materials and products to be used and any warrantees and guarantees. Your plumber should be proud to install only the best plumbing products and materials. Often, especially with plumbing fixtures, you will recognize the brand names of the best manufacturers. You may pay more for these plumbing products initially, but installing quality plumbing materials can save you money in plumbing repairs and replacements in the future.

    Once your plumber has given you a contract, read it entirely and be sure you understand all the terms and exclusions before signing it. This contract will protect you and your property, as well as your local plumber. So never sign a blank or incomplete estimate. You may write in additional requests or verbal agreements you’ve come to with the plumbing company representative, including start and end dates, no-later-than clauses that stipulate the date by which all work must be completed, or any bonuses you want to offer for early completion.

  • Be a Good Customer
    Simplify the Job for Your San Francisco Plumbing Company

    One of the easiest ways to get the most out of your contract with a local plumbing contractor is to be organized. This way, you can save the plumber time and save yourself money. You can reduce the billable time by having a written list of specific items you want addressed and a list of questions or concerns you want to talk about with your plumbing contractor.

    If you have a leaky sink or under-counter pipe leak, move all household items from the area so the plumber doesn’t have to spend his or her time clearing a space in which to work.

    Keep children and pets away from the area where the plumbing contractor is working for their safety and the safety and convenience of the plumber.

    Ask your plumbing company representative if there is anything you can do to help speed the job along. They may have specific suggestions of steps you can take to aid the plumbing repairs or new plumbing fixture installation and to shorten the duration of the job.

    How Can You Be a Good Plumbing Company Customer?
    It’s your plumber’s responsibility install quality plumbing systems and fixtures using the best possible techniques. But you play a big part in the success of your plumbing repairs and installations, too. Here are a few simple steps you can take to be a good customer when hiring a San Francisco plumber.

    • Be clear and upfront with the plumbing contractor. Let them know what you expect from the plumbing repairs and installation, the long-term outcome you’re expecting and specific ways the plumbing company can satisfy your expectations.
    • Remember, a smile goes a long way.
    • Before you hire a plumbing service, restate your expectations and goals, and reiterate to the plumbing company representative your understanding of the agreement. Most problems with local plumbers occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.
    • Ask your plumbing contractor if you should call to check on the progress or if they will call you with updates.
    • Be sure your San Francisco plumbing service representative has a phone number where they can reach you at all times. The plumbing work will move along more smoothly if your plumber can reach you for updates, questions or work authorizations.
    • Return calls promptly when your plumbing contractor contacts you.
    • Pay your contractor promptly.

Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship. Things may go smoother and problems may be more easily resolved.

Check The Work
Compare the Invoice and the Completed Plumbing Work

When your plumber has completed the work and before they leave the premises, most good plumbing companies will give you a written invoice for the work done. This invoice usually includes the following:

  • The name, physical address and license number of the plumbing firm.
  • A complete list of all work performed.
  • An itemized list of all new plumbing fixtures, materials and replacement parts.
  • The total cost, including the amount due for labor and plumbing materials.
  • Any applicable warrantees or guarantees provided by the plumbing product manufacturers and the plumbing company.

It’s smart to compare the work that was actually done to the written invoice. Ask your plumbing company representative to accompany you on a walk through the job site and show you the plumbing repairs or new plumbing installations. Check the work completed against the invoice. During your walk-through, ask if there are any special instructions for operating your new plumbing fixtures and the best steps to take in maintaining them. If you have questions about what work was done or how the installation was completed, ask your plumber before he or she leaves the job site.

Written Warranties
Ask for Written Proof of Warranties

Get proof of warranty coverage before your plumber moves forward with the plumbing services. Not all plumbers in San Francisco back up their work and products with warranties, but get all warranty terms in writing if the plumbing company you’ve chosen does. Your written warranty should include:

  • The plumbing firm name, physical address and contractors license number.
  • What plumbing products and work are covered, including whether the contractor will replace or repair the plumbing or give you a refund if you have to place a warranty claim.
  • Your responsibility if you need warranty work (i.e., if you have to pay for labor when filing a claim for plumbing warranty work or pay a prorated amount).
  • Terms and limitations of the new plumbing or plumbing repair warranty.
  • If the plumbing warranty coverage is transferrable to the new owner if you sell your home.
  • Any exclusions to the warranty and guarantee coverage must be in writing.

Q: Why won’t some plumbers in San Francisco give estimates over the phone?
A: Many good plumbers won’t give estimates over the phone because it can be hard or impossible to accurately diagnose a plumbing problem without seeing it first-hand. Since plumbing fixtures and materials greatly vary, plumbing contractors who give estimates over the phone may end up changing the diagnosis and the fee after arrive on the site to repair the problem or install the fixtures.

However, many plumbers will give free estimates when they come to look at the plumbing problem in person. Others may charge for estimates but might apply the fee toward your repair costs if you hire them to do the plumbing repairs.

Q: Is it an advantage to hire a San Francisco plumber who carries parts and equipment in their work trucks?
A: It can be an advantage to hire plumbing companies who has a well-stocked work truck. These prepared plumbers can usually repair common plumbing problems faster because they have with them all the materials required, rather than having to drive to a plumbing supply store.

Q: My plumber wants me to sign a Waiver of Right to Cancel for my emergency plumbing repairs. What is this and is it legal?
A: In the state of California, consumers who sign a contract with a company that comes to their home to provide a service or product have three days to cancel the transaction. However, while that might be a protection for the consumer in some cases, it can cost plumbers thousands of dollars if a consumer decides to cancel the contract after an emergency plumbing service has been rendered. That’s because unlike products, consumers can’t return services, so if a customer cancels the transaction, the plumber will have, in essence, don all the work for free.

For that reason, some plumbers ask emergency plumbing customers to sign a Waiver of Right to Cancel, meaning that they accept and will pay the charges for the emergency plumbing repairs. Asking a customer to sign this waiver is legal, but only if the repairs are for a true emergency. To protect yourself from plumbers who try to take advantage of customers by asking them to sign a waiver in a non-emergency situation, make sure the repairs you’re having done are truly required immediately.

Q: How can I prevent drain clogs?
A: Frequently hiring a plumber to unclog your drains can get to be expensive. If you find yourself regularly calling your plumber to fix clogged drains, there are some simple solutions that can help you avoid trouble in the future.

  • First, find out what type of pipes you have. Older pipes such as iron pipes or galvanized pipes can rust and clog more easily. You may choose to hire a local plumbing company to repipe your home using copper or PVC pipes, which are less likely to clog and will not rust.
  • Install stoppers and hair traps on all your sinks and bathtubs.
  • Do not pour cooking grease or other liquids down your sinks that may solidify when cool.
  • Regularly flush sinks and bathtubs with running water.
  • Remove hair and other debris from sink stoppers before it can be flushed down the drains.
  • Never use your toilet as a garbage disposal or flush baby wipes or paper towels.

Q: We rarely use our guest bathroom. Is there anything we should do to keep the plumbing and fixtures working?
A: Toilets, piping and fixtures should be regularly flushed with water. This keeps the water traps full and avoids the backflow of odors and gasses into the home. Once a week, you should use or turn on the fixtures to keep them functioning. You can also pour a bucket of water in each toilet, sink, shower and floor drain in the unused bathrooms in your home.

Q: What are on-demand water heaters?
A: On-demand water heaters, also called tankless water heaters, heat water as you use it rather than heating and storing hot water in a tank. Because tankless water heaters don’t waste energy storing and maintaining the temperature of unneeded hot water, their operating costs can be up to 30 percent lower than those of a traditional water heater. And with the emphasis on energy-saving appliances, tax credits may be available to consumers purchasing an on-demand water heater.

Q: Should I buy a low-flow showerhead or low-flush toilet? Why?
A: Low-flow plumbing fixtures like low-flow toilets and low-flow showerheads save substantial amounts of water over traditional showerheads and toilets. This saves water, energy and expense. Numerous water-saving fixtures have been available since the National Energy Policy Act that mandated low-flow toilets was passed in 1995. While some consumers complained that early models of low-water fixtures had weak pressure and didn’t work as well as the standard fixtures, modern.

Q: What other water saving and energy saving plumbing fixtures are available in San Francisco?
A: These days, there are many options for energy-saving plumbing fixtures, or green plumbing solutions. Some include air-assisted toilets, gravity toilets, power-assisted toilets, aerators, green plumbing fixtures, tankless water heaters, gray water recycling fixtures, composting toilets, dual-flush toilets, waterless urinals, sensor-operated faucets, solar water heaters, hot water re-circulating pumps and many others. Call your local plumbing contractor in San Francisco for more information on available water-saving plumbing products and which ones will work best for you.

Q: My drains are running slow. Can’t I just use a Liquid Plumber-type drain cleaner?
A: You may be able to fix clogged drains and stopped up sinks by using drain-cleaning chemicals you buy at the store or a non-toxic baking soda drain cleaner. However, for tough clogs that you can’t clear after a few attempts or drains and pipes that clog constantly, you may need to call a San Francisco plumbing company to professionally remove the clog or snake out your pipes and drains to keep clogs from forming in the future.

Q: I think tree roots may be growing in our pipes. What should I do?
A: First, have a good plumber confirm that you have roots in your piping. Some plumbers in San Francisco have camera equipment that can prove where the problem is, that it is roots growing in the pipes, and can give them a view of how to repair the problem. They can also advise you on the best method to prevent the problem. This may entail removing the bushes or trees that are growing into the piping, using a root-killing product, replacing the affected pipe with a stronger material, or snaking out the pipe or using high-pressure water to jet out the pipe and line it with an epoxy material.
