After my home inspection, the inspector recommended replacing the innards of a toilet on the main floor. He recommended a particular type that has no moving parts to wear out. I called Stahl, as they had been my mother's plumbers for years. When I made the appointment, I was very specific as to the brand of parts I wanted. I was told it wouldn't be a problem. An old man showed up, and said he'd replace the innards with brass fittings, not the plastic kind that had been recommended. The brass would have been significantly more expensive (3x), and could wear out over time. I said no; I wanted what had been recommended. The old man explained that the brass fitting were better quality, and all he had on his truck. He said the (ASHI certified) home inspector didn't know what he was talking about. He said that if I wanted the substandard parts that would only last a year or two, he'd return to his shop, get what I wanted, and come back. He said that I'd be charged for the time. I said I would not pay for the time involved with going to get, and returning, with parts he should have brought in the first place. He then said I'd have to schedule another appointment. I said if I had to do that, I wouldn't pay for this one, as I shouldn't be charged twice for one job, and he didn't do any work on this call. He then said he'd make me an agreement. If I don't ever call him again, he'll never work for me. I agreed. I got another plumber to repair the toilet with the parts that had been recommended, and I haven't had any problems since. It's been almost 28 years (I couldn't write this review back then) I also have not called Stahl, will not, and can't recommend more strongly that no one else should either.
