"Carlos did a super job, kept area clean and showed me the work both before and after. This is the second time I've used Tony's Plumbing - they are a really honest and professional company. My "go to" plumber for sure! Hire with confidence, they do not rip you off like so many others."

"Western Rooter to the rescue again! I had a small underground leak which appeared to be due to a bad sprinkler valve. A sprinkler repair company determined that it was not a bad sprinkler valve and thought it was due to a leak in the main water line. Daniel and Alex dug down to find that the leak was coming from a very old (at least 36 years) broken pvc line. After much testing and head scratching to try to figure out where the water was coming from, they decided to "chase the pipe." After much digging, they found that the very old broken pvc pipe was hooked up to a sprinkler valve that was buried 18 inches underground that had not been capped--only turned off. Roots from a nearby tree had opened the valve which caused the leak--crazy! The current sprinkler system has been the same one since we moved into the house in 1988. It took 36 years for the underground leak to occur!"

"Unfortunately there was a defective fitting that caused a pipe to burst. The house was vacant so we didn't learn about it until the next day. Alvin bent over backwards to repaire the damage, replace the ruined water heater, and make us whole. He even changed the water heater to a tankless model because the location of the ruined water heater didn't meet code and tankless was our only option."

"I had Glover Plumbing Solutions replace my old yucky tub with a Delta rainforest Walkin Shower, as well as my old tank water heater with a Navien 240A2 tankless water heater and recirculation system. Ryan did a great job with the installation and made sure everything met California code requirements. The workmanship was excellent, everything was tested before he left. Im beyond thrilled he gave me the bathroom of my dreams and im hard to please. I seriously recommend this young man."
