Get matched with top tankless water heater repair pros in City-of-industry, CA

"It went very well and all the issues were resolved quickly. Adan was very professional and confident service person. We highly recommended Payless water heater and plumbing."

"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!"

"Victor from L.A. Plumbing Pros came out Jan. 28 to start my water heater. He was here within a half hour of his call. He gave me a ball park price over the phone for doing the job but told me when he got here he did not realize I was within a couple of blocks of the Altadena fire. He said there is no charge. He was very gracious and kind and I am so grateful to him. He got the water heater to work in just a couple of minutes. Thanks again Victor."

"Very professional. Prompt. Tankless water heater has been working fine ever since. Hired another plumbing company before calling G M C. They were half the price. But did not solve the problem. David with G M C diagnosed the problem. Completed the work. No problems ever since. Thank you Angi, thank you David and G M C Plumbing."

"John's plumbing pointed out that, for not much more money than a regular water heater, that I could get a tankless water heater and save on monthly gas bills. They were right. I am saving about 40 % on the gas bill for the water heater because the only water heated is the water I need. I purchased a Navian Tankless 240 unit which has a top rating on Consumer Report."
