I am renovating my lower bath ( on concrete floor) and the cast iron flange has corroded. I was planning to cut it and snug fit a PVC Flange inside the cast iron pipe Talked to a plumber I know and he said it need to be iron flange sealed with molten lead. I am thinking using epoxy glue ( the liquid weld type) around the PVC flange and insert it inside cast iron pipe. Is it a bad idea ? Is the plumber right, or just selling his business ( molten lead means I sure need a plumber)

Hello,e hose My kid bought a house and it needs a bit of work. No big deal but I'm encountering one thing I've got a question about. The previous owners had a small washer/dryer stack in a laundry area. Apparently, they had the washer drain hose go out through an adjacent bathroom sink drain. The hose was attached to a rubber connector with aircraft-type hose clamps. Said kid bought a LG combo washer/dryer and I'm wondering which of the two options for drainage I should consider - space is at a premium: I could install the drain hose using a cheater valve directly into the bathroom drain pipe as it was before except there'd be that cheater valve, or; I could install some type of standpipe for a drain - again, it would need to go into that bathroom sink drain but there'd be a j-trap. The main concern is providing air for the drain so it doesn't siphon. Suggestions? I'm not thrilled about either. Thanks!
