Just wrapped up a two day water repipe of an old house, ripped out a bunch of galvanized, ran new copper from the meter into the basement mechanical room and to a few fixtures, then PEX to the rest. Second floor bath, main floor bath, laundry, silcock, etc. Pretty involved, lots of plaster getting ripped out, lots of naughty words said, the whole time cussing the home flippers that threw down all new tile, cabinets, countertops, tub, surround, vanity, and found ways to screw the plumber at every turn. I get why they do what they do but I still curse their names. Anyway, wrapped up, collected a hefty check, went home and tried to forget about the job, they called back and said the tub was leaking when they showered. So I went out there today and found this. Some bum had ran a screw directly through the shower riser, we must have done enough jostling to cause it to start leaking. Luckily the leaking started before they fixed all the plaster we ripped out I suppose.
