If I could give Greg Principali of Nickel Plumbing zero stars, I would. He was hired to fix a leaking RPZ. Very simple, he assured me. Quick repair, in and out, and he charged a stiff $200. Except that when it began leaking immediately after he left and I contacted him to schedule a return visit, suddenly he stopped answering texts and phone calls. Completely unprofessional, completely dishonorable. Whatever happened to standing by your work? He certainly had no problem running straight to the bank to cash my check! Bad guy, don't waste your time, find somebody more reliable and trustworthy.
