Get matched with top tankless water heater repair pros in Rancho Cucamonga, CA

"Perfectly. They cleaned everything up, explained how the system worked and how often it needs attention, and hauled away the old hot water heater. They arrived on time, worked steadily, and finished before dinner time."

"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!"

"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"On call for emergency repairs, very reliable and knowledgeable."

"Service Flow Plumbing did an excellent job flushing my tankless water heater at a very reasonable cost. Rose provided outstanding customer service from start to finish, and Andrew—the technician who performed the flushing—was extremely professional, knowledgeable, and sure to explain everything clearly. The whole process was smooth and stress-free. Highly recommend their team!"

"Mike was great! He was friendly and knowledgeable. He let me know all the options for replacing my water heater and did the work quickly and neatly. Will definitely be calling him again!"

"They did an amazing job with the hydro jetting. Pipes are clean and clear of debris."

"My water main went out on Christmas Eve leaving me without water, Wes offered to come out on Christmas day to make the repairs. I told him we could wait until the next day, he arrived on time, dug up my very rocky soil to get to the water main and made the repairs. The customer service was great and he explained everything to me every step of the way. The cost was also reasonable. I have asked that he return to make an additional repair later this week. He definitely has a repeat customer."

"Prompt service — Daniel came out the same day to perform routine maintenance on my tankless water heater. He was professional, efficient, and explained everything clearly. He also gave me helpful guidance about planning and budgeting for a future replacement, which made the process feel much less stressful. I appreciated the transparency!"

"Wes came out to look at a water heater issue my mom was having. He took the time to explain what the issue was, offered options, and ultimately replaced the water heater and some of the old piping around it that needed it. Never had a problem since. After that, we also hired Wes for other pipe replacement in the garage and in the laundry area. Again, haven’t had an issue since. He is a professional and I appreciate trusting that the job is done right and not being gauged for it. I would absolutely recommend Rapid Rescue Rooter & Plumbing."
