    Can't figure out how to loosen or tighten this tailpiece

    I've done a fair amount of household plumbing, but I cannot for the life of me figure out how to get this tailpiece looser or tighter. The collar slides up and down on the tailpiece (see second pic how the collar can be slide up from the flange beneath) but it doesn't spin, even with one pair...

    1st story lav sink drains slow, 2nd story lav trap gets sucked dry: help?

    I inherited a pair of problem sinks, and I haven't been able to solve the problem. House was built in the late 70's. These two bathrooms are on the same stack, and I'm guessing that the problems are related. The 1st story lav sink drains very slowly. The trap is completely clean. The 2nd...

    Proposed schematic for adding washing machine and kitchenette

    I'd like to add a 2nd-story washing machine and a basement kitchenette to what I believe is a 2" vent for a floor drain. Would you review the attached schematic? I'm guessing about how the existing floor drain is plumbed, since everything's encapsulated in the basement floor. What I see is...

    Can you check my DWV rough-in?

    Hi, Can you check my DWV rough-in? I've attached a sketch of the roughin with the non-obvious fittings labeled, along with the bathroom layout. To give a scale, the upstairs full bath on the right is 6.5'x6.5'. The 3" branch that everything drains into will run in a soffit below the...

    Replace copper lines with PEX?

    I'm renovating a Cape Cod in Dayton, OH, including gutting a half and full bath. The house was built in 1940. There's evidence of previous water damage, but I can't tell for sure if it's from the drain lines or copper lines, though I suspect the drain lines, since they're in worse shape. I...
