The repairman was very knowledgeable. He was quick with his work and to the point. No complaints as far as the job he did, his speed, the work looks good, and he was professional. I will raise two concerns/critiques.1. I offered to move everything under the sink out, to be completely empty. He assured me that was not necessary, he just needed such and such much space. But when he took off the pipe, water everywhere underneath. He moderately dried it, but everything that was not in his way got wet and had to be dried, as well as the floor of the space. I should have moved everything out and provided him with a beach towel- would have saved me time and work afterward.2. He told me the problem was a clogged pipe deep in the line, he said this before he had done anything, removed the piping under the sink, anything at all. I took his word for it, which was an expensive job. The real problem was the chuck of pipe he removed was packed full of rice someone (I wont say who) tried to put down the garbage disposal the evening before. He didnt show me the rice until after he had snaked the line. Was snaking the line bad? No, but it was not the real problem, and it cost me far more that just clearing the pipe below the sink. I dont know anything about unscrewing piping, but I guess I should have done that myself and save a few hundred.
