I explained to him why I felt it still accurately reflected my experience (and I gave it a lot of thought). He apparently was not pleased with my response and has asked me to find someone else to inspect my backflow valve--which is his right.

However I did not find this latest experience very positive, hence the updated rating of 3 stars.

Gavin advised me on what's needed, when the valve might need to be replaced (not yet) and why the checks are done.

F&A Plumbing is now my go-to plumber for our 100-plus year-old San Francisco building…read more The insurance company for our 4-unit building required automatic earthquake shut-off valves on the 4 gas meters, and gave us a very short time to comply.

Big mess, lots of gross water in places it shouldn't be, and my valiant plunging efforts were doing no good at all. With guests checking into the Airbnb in a short period of time, I called F&A Plugging and Rooter with an urgent request to send a plumber to my Airbnb that very day. Not only was the lady on the phone very nice, but she understood the urgency of the situation. After quickly collecting information about the situation, she let me know that a plumber would be able to come that day, in about two hours. I was so relieved. Then, something even better happened. About 20 minutes after I booked the appointment, the plumber himself called me and asked if he could come by in 30 minutes - a full 1.5 hours ahead of schedule! I agreed, met him at the place, and he assessed the situation quickly and professionally. He diagnosed the plumbing issue, made a recommendation on how best to fix it, gave me a price, and got to work. Within another hour the problem was fixed. I had a great experience with F&A Plumbing and would absolutely go back to them if any other issues ever arose.
