The plumber was on time (on a Saturday, no extra charge), reviewed the 3 services to be done, gave me a quote on the spot and got right to work. He used the new parts which I had purchased, answered any questions that I had, and generally had 3 bathrooms in good working order when he was done (a new toilet shutoff valve, a properly installed flush mechanism with a non-leaking tank, and a non-leaky hand-held shower nozzle). He offered a senior discount without my asking and was done in about 1.5 hours. I would recommend Bosco Plumbing to anyone.
