"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!"

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"Clear All Rooter is a family owned/run business. The owners and home office personnel are very aware of the project, keep the customer updated daily, provide photos of the plumbing techs coming to your home and the time they will arrive. All of the employees and owners are very courteous, listen to your questions, answer those questions very knowledgably and complete the work extremely professionally. They review the project in person, prepare and provide an easily understandable estimate of the work to be done and obtain your OK and signature before any work is started. The plumbing Techs (Jaime and Angel on my 3 jobs) were very nice, explained each day what they would be doing (in terms that me as a Senior would fully understand), were very professional and knowledgeable regarding their work, and completed their work each day on a very timely basis. My 3 jobs were replacing my entire front yard water pipe system (house to street), replacing my entire water pipe system under the house and replacing the entire sewer pipe system under the house (they also replaced my water heater). They did an absolutely excellent job on all facets of the jobs, cleaned up thoroughly each and every day and completed all of the work in a very timely manner (7 days). I would very, very highly recommend Clear All Rooter to anyone and everyone that asks for my reference of a "good plumbing company" to do work for them and I will hire them again myself for any future plumbing jobs that I may have."
