Roy Coto Plumbing
Company Overview
Backflow inspection. Every model available.
“AWWA certified” backflow inspector.
Licensed and certified in San Francisco and San Mateo counties. Same-day service available.
With 25 years of plumbing experience, I launched my own backflow testing business. While I hold a plumbing contractor license, I have shifted my focus to backflow testing and repairs for systems 2 inches and smaller. I focus on San Francisco, while also providing services in San Mateo County.
I grew up in Florida and relocated to San Francisco in 1970. I completed a three-year stint in the Army in the mid-seventies. I tied the knot in 1987 and relocated to Pacifica. I spend my leisure time diving, kayaking, foraging for mushrooms, and volunteering at The Marine Mammal Center.

Stuart L.Roy has done our backflow testing for years. Always helpful, fast and reliable.
We have been using Roy of RC Plumbing certifying all our property in our property management accounts. Dennis Etorma Property Manager Saxe Real Estate
Roy is fast, efficient & friendly. He even explained & showed me why a backflow certification is required. And, he is upfront in his estimate which never wavered. I will rely on Roy again, next year.
Monica M.I can not believe I am the first review. Roy has worked on our place for at least 9 years and he is GREAT!! Reliable, reasonable, professional, easy to talk to. Strongly recommended!!
