Flow Masters Plumbing and Heating

We came across Flow Master through online search. We were interested in doing a hydro flush to our business to make sure the flow of our system is up to date. Juan came and inspected and provided us with a quote. He was very attentive to where the main lines came from and explained how they would flush from the back of the restaurant to the front of the street. Highly recommend this company. They believe in up front customer service. Thank you

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!!

The entire team at Flow Masters was professional, efficient and well organized. From our on-site estimate to their quoting system, we had the work done within a few days. A special call out to Alberto who serviced our house - he was terrific and detailing the issues we needed to understand to make decisions, worked quickly and was terrific about documentation, questions, etc. Overall a GREAT experience!

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, quick 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!

Connor had initially replaced our expansion tank in our radiant heating system. He was very prompt and provided speedy service. Knowledgeable plumber. Would use them again. The second time, Christian had come and done our annual maintenance for our broiler and radiant heating system. He was prompt, thorough and diligent in his work. He took his time looking through everything and running multiple tests/checks to make sure everything was working correctly prior to finishing up. This company is pricy compared to others but they match this with very service and good customer care.

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!

Our boiler was out... not hot water, no floor heating... and Connor stepped up big time. Very quick turnarounds for assessment, quote, ordering parts, and the work. Oscar did great work. Very professional, trustworthy. Highly recommend Flow Masters!

Very happy with my new Viessmann installation, expertly installed by Flow Masters Plumbing. It serves a hydronic air handler and an indirect fired hot water tank. Excellent quality, clean install, super professional. I really appreciate that Connor and team followed up on everything I asked them about. Flow Masters was also the only competent plumbing company in the Bay Area (I looked at ~20 companies) who had a clue about more complex hydronic systems. Excellent customer service and beautiful, well-engineered install. Another contractor stopped by for something different and remarked on the clean lines of the install. Very well done.
