Very professional technician came out during the expected time slot. He took care of our problem with our faucet exactly as we hoped, and was super open to me watching. He answered all my questions and was very personable and patient. Not the cheapest option I saw, but it was worth it to me to have it taken care of professionally and correctly.

I called Flow Masters to replace a roof drain and overflow. I spoke to so many plumbers who said it was a roof drain and vent pipe. Juan took one look at the photo of the rusted roof drain combination and immediately recognized what I needed and sent me a photo of the correct part. They were able to start the work very quickly, and coordinated with our roofers. Fergal and Juan were prompt, very communicative, and did an excellent job. I highly recommend Flow Masters.

I got a water valve monitor installed by Flow Masters Plumbing. The experience was seamless and easy from getting a quote through to installation. Juan, our technician, was knowledgeable, speedy and patient. He installed the device within the estimated time and stayed to make sure my app successfully connected with device. Great experience all around. Would seek them out for future water and plumbing needs!

Flow Masters was a life saver!! We had a leak from our kitchen sink/ garbage disposal but we weren't sure where it was coming from. I used Yelp Request a Quote, and within minutes Flow Masters got back to me. I sent the request Thursday night @ 8pm & they had confirmed an appointment for 8am Friday morning. LIFE SAVER!

The technician that came, Emmett, was EXCELLENT. He found the leak, told me it had been going on for some time (UGH), and fixed it all within 30 minutes. He was so polite, efficient, and even dealt with my barking dog. Thank you Flow Masters! Will be coming back for any plumbing work we need!

Alan and his team are genuine, detail oriented, and do high quality work. We had a heat pump water heater installed and they were very responsive and hard working when we needed some follow ups. They were respectful to people in the building and very knowledgeable about permits, tax credits, and converting from gas to electric appliances. We will certainly be using them again for any plumbing needs. Could not recommend more, all 5 stars are well deserved.

Quit Carbon ( https://www.quitcarbon.com/) recommended us Flow Masters Plumbing to replace our gas water heater. They installed a heat pump water heater. The team at Flow Master Plumbing is so knowledgeable: they are very familiar with the latest clean-tech solutions and their plumbers did a high quality work. They also helped us with getting our California rebates for switching to electric. Alan and Emmet were always available and very responsive when we had questions. I highly recommend them for new installations.

30+ years as a homeowner I've seen a lot of plumbers, but Flow masters is the best plumbing company I have ever worked with. Whenever I call even after hours, someone would pick up their response time was quick and they would've done the repair work the next day, but they had to order the part, best of all they're their estimate was so reasonable.
Call them now!

My husband called Flow Masters Plumbing because we were hearing loud noise in the pipe, they were very responsive, they came to the house to inspect the same day and helped us to resolve the issue even without charging us. Best business in town!

Jose and Nixon from Flow Masters came out to temporarily move our water heaters to the middle of our basement as the first phase in a foundation replacement. They were communicative, professional, friendly, and efficient. The work and clean-up was very tidy.
