I had a problem with my basement unit getting flooded twice in 2 years after heavy rain. We had to install a backflow preventer in the bathroom. First this required doing some thorough camera work. Juan was very diligent and took the time to find the best solution and do the job correctly, not hastily. I can tell he takes pride in his work. He always picked up my calls, and was respectful of my time. I would 100% recommend Flowmasters and Juan to solve any complex plumbing issues.Response from the ownerHi Mr.Kumar, Thank you for your kind words about Juan and Flow Masters! We're thrilled to have been able to assist you with your basement flooding issue. Your recommendation means the world to us! Cheer!

Not the cheapest option I saw, but it was worth it to me to have it taken care of professionally and correctly.Response from the ownerHi Brent, We greatly appreciate your review! We strive to provide value through professional and correct service. Thank you for choosing us to take care of your faucet issue! Cheer! Mr. FrancisMr. Francis ★★★★★ If you’re looking for a company that takes its projects seriously, dedicates the time and it’s experience to their successful completion, offers multiple options to the owner and thoroughly explains each ones advantages and disadvantages,, then Flow Masters plumbing is the company to call. They have the proven ability to successfully complete projects within the guidelines required by regulatory agencies and also stay within the owners budget. We asked them to install a heat pump water heater in a space designed for a gas water heater, and they made it look like it was designed that way when the house was originally built over 30 years ago. We are very happy and completely satisfied with the results. Choosing Flow Masters plumbing for this project was the best decision I’ve made long time. No regrets!!Response from the ownerHi Bozo, Thank you so much for your glowing review! We appreciate your trust in us and are thrilled with the successful outcome of your project.

We called flowmaster and received live person who told us someone would call us within 15mins who was knowledgeable about our boiler. A technician Conor called us back in less than 5mins and arranged for a time to come out in the next hour or so. Connor arrived and determined we needed a new water pumped. He said he or someone else would call us on Monday morning by 8am. The office called us at 7:50am and scheduled a time that worked best for us to do the repair. Christian arrived on schedule and was very friendly. He confirmed why he was here and explained in detail how he was going to repair the issue and test afterwards. He made sure every location had hot water before allowing me to sign off on the completed job. I just love this company's prompted professional customer service!Response from the ownerTenah, thank you for the kind review and for the consistent work you give us over the years, we appreciate it. We look forward to working together for many more years.

Call us any time 415-751-1933 Christina RuddyChristina Ruddy ★★★★★ We highly recommend Flow Masters Plumbing. They came out to do maintenance on our radiant heat. All seemed well, but we lost heat and hot water by bedtime. We couldn’t figure it out! Alberto M. came out the next day to see what was happening. He spent all day going through everything he could think of. Soon, he was joined by his supervisor, Connor, and our original service tech (sorry, I forgot his name). The guys never gave up! They replaced things, tested, called the manufacturer. Finally, Connor figured out that a small, but necessary part had gone missing during the maintenance work from the radiant heat device. He was able to find a new part and by 7:30am the next morning, Alberto was back to install the part and get our heat and hot water working again. Not having heat and hot water is an inconvenience, but all three of the Flow Masters Plumbing guys had good attitudes, they wanted to make it right, and they worked hard in a frustrating situation. They were friendly and professional. We will use them again. Thank you!Response from the ownerHi Christina, Thank you for your kind words and recommendation! We're glad Alberto, Connor, and our team could resolve the issue with your radiant heat promptly and professionally. We appreciate your understanding and look forward to assisting you again in the future.
