"Removing the old disposal proved as challenging, it had not been mounted correctly: threads were stripped AND corroded. He was done about 45 minutes later. He checked everything, but no hot water was coming out. He bled the system, and corrected the problem. I had him inspect a couple of other faucets in the condo (that had been vacant for almost 2 years), which he did very graciously. I had a couple of coupons, and he let us use both. Pipe Doctor's Plumbing's rate may have been higher than the competition, but the job was well done. We would recommend them to anyone."
