About One Source Plumbing and Rooter

One Source Plumbing and Rooter, Inc. provides a complete range of plumbing services for residential and commercial clients throughout the San Francisco Peninsula. The company has the training and equipment to install and repair all types of plumbing systems, and its technicians are available 24/7 to handle emergencies.

Owner Mostafa Sowadah says One Source Plumbing and Rooter’s customer-oriented approach to plumbing has been an important part of its continued success. “We’re known for having good chemistry with our customers—we pay attention to details and make recommendations that we know they’ll appreciate. Plumbing problems can be stressful, but our customers know that once they call us, we’ll be there to take care of everything.”

One Source Plumbing and Rooter focuses on performing “long-term fixes” that maximize the lifespan of its customers’ plumbing systems. “We want our work to be here long after we’re gone, so we take a lot of pride in finding the best solutions for each situation,” says Mr. Sowadah. “We don’t take shortcuts; we believe good, honest work will lead to a loyal clientele base that’s quick to refer us to others.”


Maintaining customer satisfaction is a crucial aspect of any business. For One Source Plumbing and Rooter, Inc., the best way to achieve customer satisfaction is to take the long view on every job, regardless of its size. “We take a lot of pride in our work, which is why we never take shortcuts,” says owner Mostafa Sowadah. “We’re not concerned about short-term profits or quick turnovers–at the end of the day, quality work and customer satisfaction are the things that generate our long-term success.”

One Source Plumbing and Rooter has been providing plumbing services for residential and commercial clients throughout the San Francisco Peninsula since 2013. The company has the in-house capabilities to install and repair all types of plumbing systems, and it offers 24/7 emergency service for the convenience of its customers.

Unlike less experienced plumbing companies that take an “assembly line” approach to every job, One Source Plumbing and Rooter focuses on building relationships with its customers and helping them get the most value out of their plumbing projects. “As a small business that has built itself from the ground up, we understand the value of the dollar and know how hard our customers work for their money,” says Mr. Sowadah. “So, instead of overcharging them and hurrying through their jobs, we take the time to provide them with quality work at reasonable prices.”

Another distinguishing attribute of One Source Plumbing and Rooter is its ability to provide customized solutions for a wide variety of plumbing issues. “With our industry knowledge and experience, we can find solutions to even the most complex and unusual problems,” says Mr. Sowadah. “On top of that, we do our best to offer economical alternatives for budget-sensitive customers. We want our customers to know that once they call us, we’ll be there to take care of everything.”


Thanks to recent industry innovations, many once-complex and time-consuming plumbing processes now have faster, simpler solutions. “The plumbing industry is constantly changing, from products and techniques to code regulations, so it’s important for a plumber to stay up-to-date with these developments,” says Mostafa Sowadah, owner of One Source Plumbing and Rooter, Inc. in San Francisco. “A plumber who’s current with industry trends will be able to offer the latest and greatest technological innovations.”

One such innovation Mr. Sowadah points out is Ridgid’s ProPress copper piping system. “ProPress is a recent innovation for fitting pipes that’s becoming huge in the industry,” he says. “In the past, pipes had to be welded together with a blowtorch, but the ProPress system utilizes special fittings that tighten securely to the pipe when pressed on by the ProPress machine. In addition to saving a lot of time, it reduces the risk of fire or burns from welding. The only downside is it’s a system, so you have to purchase the ProPress machine and use compatible pipe fittings, which are more expensive than standard fittings. That being said, the time saved typically offsets these additional costs.”

Even though it’s not as recent, another innovation that’s had a substantial impact on the way plumbers work on sewers is trenchless line replacement. In the past, in order to replace a broken sewer pipe, plumbers had to excavate the full extent of the pipe. This meant any area of the home that the pipe ran beneath (lawn, sidewalk, patio, driveway) had to be torn up, which resulted in a disruptive, time-consuming and extensive job.

With trenchless line replacement, plumbers now only need to dig two holes: one at each end of the pipe section being replaced. This allows the new pipe (typically a flexible, high-density polyethylene) to be pulled through from one end to the other, using the old pipe as a guide. “Many people still aren’t familiar with trenchless sewer replacement, but they’re always appreciative of it when they learn how the old method works,” says Mr. Sowadah.


Q: Can you tell me if my home’s plumbing is up to code?

A: Definitely. Every city has its own particular plumbing codes, so it’s important to have a professional assess this for you. In addition to telling you whether your home’s plumbing is up to code, we’ll be happy to perform any necessary upgrades.


Q: Do you repipe houses?

A: Yes, we’re able to provide whole-house copper repiping services.


Q: I have an antique plumbing fixture—does it need to be replaced or can it be repaired?

A: If you’d prefer not to replace an old plumbing fixture, we can usually just repair it.


Q: Do you provide a warranty on sewer work?

A: Yes, we offer a 20-year warranty on our sewer work, which is more than most companies offer.
