I had a problem with my kitchen sink not draining. Had 3 other plumbers come out to look at it and was not able to resolve the issue. Coy hydro jetted the line and was able to do what all the others were not able to do. It not only fixed my kitchen drain, but cleaning out the drain fixed the slow drain for my washer also. He was very courteous, explained everything as he was doing it and cleaned up all the mess so you couldnt even tell I had a huge sludge pile on by back patio. I really appreciate his can-do attitude and his ability to fix what others could not. I am keeping him number forever.Doris (happy home owner)
