Flow Masters Plumbing

Did the work just fine. However, they are very expensive and no description of specific work done on the receipt. When I called for more info never received a call back.

Great experience! Just before a holiday weekend, we lost access to hot water and Connor was extremely responsive. He and his tech came out quickly and repaired the problem (we have radiant heat and not many plumbers know how to work with our system). Great communication and quality of work. and he and his tech came out quickly, Highly recommend.

On time, does good work, and friendly, but very expensive for a ""basic"" boiler service.

I would hire again for sure. Easy to get an appointment. Very friendly people and did a great job. Thank you!

Connor from Flow Masters has saved me twice from a dying home heat system in cold conditions so far this fall and winter.

Both times, he went out of his way to secure parts on short notice. In fact, I'm writing this on Christmas Eve, when he came out at 8am to fix my boiler which died two days ago, leaving my home frigid (okay, by SF standards, but still!).

Beyond his skill, he's just super nice and easy to work with.

110% recommend.

I used them in March, and should have written this earlier. I would advise making sure u know their rates and what they propose to do. Our tub leaked and it turned out the plumber needed a part to test the drain, and had to,leave to go get it since it wasn't in his truck. Turned out he couldn't fix the problem (understandable, it was the tub, not the drain) but wow, the charge was the hourly rate of $250, for 11/2 hours due to the trip to get the needs part, so $375! No break for me in light of the fact that he couldn't fix it!

One of our hydronic radiant heating zones stopped working. Flow Masters Plumbing was highly recommended by Pace Plumbing Supplies, which was where our original plumber bought our radiant heating system. Pace also provided some install consultation to our original plumber.

Connor, who serviced our radiant heat system, was very friendly, professional and showed up with a mask on (for Covid prevention). He found the problem very quickly, addressed it and also took a quick inspection of the system to make sure everything looked good including sending a scope into the embedded pipe to make sure hot/warm water is being distributed throughout the zone. It's nice to have our heat back!
We're very happy with the service provided and will definitely contact them again for future service needs.

We had a plumbing emergency and Connor responded to us immediately and came quickly to help. We have worked with him before on our hydraulic heating and plumbing and he has always been hardworking, efficient and professional. We were super thankful that Flow Masters and Conor specifically rescued us. I would highly recomend Connor and Flow Masters!

I have had Flow Masters work on our radiant heating system as well as our plumbing in the past and turned to them again when our 60 year old radiant heating system started again having problems. Connor is a well known and trusted part of the company and it was a pleasure to have him work on our system again. First, he thoroughly diagnosed the problem and researched the best solution (versus a quick fix). He explained the rationale towards his solution and how in the long term, it was the most cost effective; it also provided the most flexibility as well as an upgrade to our present home heating system. The front office was very efficient in providing the paperwork and facilitating the scheduling (have you ever experienced calling a contractor, leaving a message and never getting a response?) and the estimate I believe to be more than fair and competitive. In addition, the work ended up to be more complex than originally planned, yet Flow Master followed through on completing the repair in a competent, professional and respectful manner consistent with their original estimate. I recommend that you first turn to Flow Master for your heating and plumbing needs.

Our project involved the complete rebuilding of an older structure in a difficult site. The building is 4 stories, divided into 3 apartments, for a total of 2800 square feet, and all of the plumbing was essentially on one wall. They did all of the plumbing from the gas and water mains on. They did 3 tankless combi boilers, all hot and cold water for 3 full baths and a powder room, 3 kitchens, 3 laundries, radiant heat for all 4 floors, 3 gas ranges and 3 gas fireplaces, and drainage systems for a flat roof and a 23 x 4 light well, all to meet demanding San Francisco plumbing codes. There isn't a plumbing problem that we didn't encounter, and there is no plumbing situation we can imagine anyone in the City might have that we didn't encounter. Our project was so complex that another contractor theorized that the site was haunted. When we checked Flow Master's references before engaging them, one reference (a general contractor) actually said that he hesitated to recommend them because they are so good he was afraid that they would get so much work that they wouldn't be able to accommodate his projects. We feel the same way, so we got Conor to promise that we would always be their clients and that, if we needed them, Flow Master would help us. Finally, our electrical contractor had a girlfriend who was a plumbing engineer in Russia, and she wanted to see as many U.S. plumbing installations as she could. We gave her permission to look at our plumbing before the drywall went up. She spent two hours at our site and then told us that she had looked at more than 40 sites, and ours was the highest quality she had ever seen. Flow Master did all of this work brilliantly, on time, and on budget, and their bid was reasonable and firm, despite the complexity. 10 stars!
