"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"Since my current water heater was 17 years old I decided to replace it before it gave out on me. I emailed Better Water Heaters in the evening with the details and got a phone call from Frans who scheduled Daniel to come and give me a free estimate the next afternoon. In the meantime I got another quote from another installer after texting photos of the current installation. Daniel’s estimate was similar for a standard water heater replacement but although I had not considered a tankless install I asked for a quote on that as well after discussing pros and cons with Daniel. Daniel then waited while I discussed this with my wife and since he could do the install the next day I decided on the tankless install and Daniel arrived the next morning and completed the install in three hours. I am very happy with the quickness and quality of the work as well as the quality of the Rinnai water heater that was installed."

"Steve was timely and quick with replacing my water heater and was very responsive when I messaged him. He also provided great suggestions and options for my water heater replacement and streamlined the bayren rebates process for me. Provided services at a very fair price compared to other plumbing services. 10/10 would go to him for future plumbing issues."

"My water heater was leaking and I needed it fixed asap because we had no hot water and I have small kids at home. Robert came, he saw the problem and fixed it fast and efficiently. He was professional and polite and the price was right. I will definitely call him again in the future. And have recommended him to family and friends. Thank you Drain Right Plumbing!!"

Customers say: Super punctual

"Guy who came gave me good advice and advised that he felt my issue was not needed for repair. He didn't try to sale me any service as he saw no need. I appreciate a plumber who isn't trying to get work out of people whom don't need it."

"Isaac and team were incredible in getting a bunch of updating old and out-of-code plumbing work done on our tricky 100-year-old house. They took time to really dig in and assess the right game plan to make sure not only that all the plumbing and vents were done properly, but that they looked great given some would still be exposed / visible under our porch. The team was communicative and courteous. Our new plumbing is working like a charm. The tankless heater and smart shutoff are cranking. And everything passed on first inspection. The inspector even commented how clean and detailed it all looked. Would recommend SplashFix for any project, big or small."
