I was worried that perhaps I may have damaged a sump pump when trying to clean it, and I sent a request in through Thumbtack. I heard from Norlan a couple hours later, and as he was in the neighborhood, he stopped by for a quick look. He checked the sump pump and verified that there was no problem with it and that it did not require work. He did not charge me for this visit/appraisal. Norlan strikes me as a knowledgeable and honest person, I will certainly turn to him when I have a plumbing issue in the future.
