Hi. What's your best practice for making the tub removable before you lay it in mounds of plastic of Paris? I read plastic somewhere but not sure if there is a best technique/thickness, etc. Is there a way? I'm worried if you put some down it would squish out the plaster of Paris too much. Also...

Hi and thanks again. Can I drain my 1.5" (could be 2" if needed) into the back of my 3" toilet drain? I don't see why not but maybe it's not best practice. Between some conduit and the joists I don't believe I have enough headroom to run the 3" pipe all the way back to the vertical sink pipe and...

Hi. Are Fernco compression donuts code in UPC? It seems like pros use them but I think I've read they are NOT code. Can't find exactly where in the UPC codebook it says one way or another if someone knows. Or is it one of those things pros do even though not code? I put one in my 4" CI hub on a...

Hi and thanks. I just need clarification on the UPC dry vent 6" horizontal rule, please. I have a CI stack in a 1916 house with a side vent at about 36" above the floor. Not code compliant with the current MN UPC code for the vanity that was attached. I'm moving the vanity to the other side of...

Hello. My situation is that I'm remodeling a 100-year old bathroom (78" x 90") were all the current plumbing/venting is on the right-hand side. I'd like to move the toilet to the left-hand side, which will actually put fixture spacing more in code and allow for a larger vanity sink. I'm in...
