Bobby came to repair a waste leak on a wall mounted toilet. Despite emailing in a complete sketch of the fittings, he arrived without any parts, or even knowing that I had sent in a sketch.
Toilet unusable at end of day. Next day he arrives with a seal that doesn't fit. Screws around for a few hours with the bad seal and silicone sealant, can't stop the leak. Bills me about $400. Says I may need a new toilet.
The next weekend I go to Barron's Plumbing Supply, and buy the correct gasket for about $15. An hour or two later toilet is on the wall and not leaking.
