"It went great! Jerry was just getting out of the hospital when I called to schedule my appointment. He answered promptly and they had someone out the next day. My water heater is no longer making the noise. They told me if it starts making noise again, they would remove and exchange for new water heater themselves. They were very professional and nice. We will definitely be hiring them again if necessary."

"Martin was very thorough and quick in installing my water heater. He also upgraded my valve which was a bit outdated. His price was fair and his quality and cleanliness of work was outstanding. I would strongly recommend him."

"The first time I called it was Easter Sunday and we had a leak in our garage which we thought was the water heater. Rescue rooter came, it was not the water heater but a copper pipe behind the water heater. They removed the water heater, fix the copper pipe, and put the water heater back. The second time was for a leaking toilet. Both times they were punctual, texted when they were on their way, performed the work in a timely fashion and the technicians were great. Whenever we have a plumbing problem we will definitely call rescue rooter!"

"Zach did an excellent job fixing my water heater. He quickly diagnosed the issue, drained the water heater, made the necessary repair, and installed a FloodStop for added protection. He was professional, knowledgeable, and took the time to explain everything clearly. The work was completed efficiently, and I really appreciated his attention to detail. I highly recommend Zach to anyone looking for a reliable and trustworthy plumber!"

"They claimed the water from my water heater was as hot as it should be but did not possess any means to measure the water temperature drained from the water heater. So the statement was based on their unfounded belief. I came up with a food thermometer which showed the water was 138F when it should have been 160. They left."
