"I was interested in getting a whole home water filtration system. California Plumbing came out and provided me several options and a lot of information on them. After choosing the best option for me, they installed it asap. I’m so happy with my new system!"

"Repaired my leaking filtration system, gave it a tune-up, corrected the back-flush setting which was wasting water/money, and said I'd get another 7 years out of it. Very happy I didn't have to replace it."

"Great job. Anthony did a complete review of the house and the current venting and recommended the proper size for the AC. The installers and electricians came 3 days later, did additional wiring and piping and installed the entire system in 5 hours."

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.

"Best experience replacing a water heater! Mickey was very professional and worked efficiently to replace our old water heater. He took the time to go over the estimate (priced fairly and competitively) and made sure that we had the equipment we needs for our household needs. He made sure that we also were brought up to code since our set up was fairly old. The experience was smooth and stress-free from start to finish. I would highly recommend Mickey and Gorilla Plumbing for future plumbing projects!"
