Hi everybody, great forum!
I've got a quick question but one that makes me a little nervous and want to get it right.
Re-doing my shower with tile, hardibacker walls and using the Kerdi drain kit with pre-fab slope and dry pack mortar for the floor, whole thing gets the Shluter waterproofing flannel then tile, pretty solid idea what to do on the tile end.
The existing floor is a 4" basement pour with 2 1/4" pvc vertical drain pipe going down to the P trap. Drain was originally off-center so I had a very good plumber chip up a hole in the concrete and center a new drain, which was a standard pvc drain made for tile. Was going to do that with an old school mortar pan. Mid-project got sold on the Kerdi drain/pan system which all the pro tile guys I know have switched to using.
So I need to:
1. cut the vert pipe, glue in a coupler piece and a short section going up to the new kerdi drain piece (which is also pvc), and glue that to the new drain flush with the floor.
2. patch the concete hole (about 10" wide by 3' long), then skim coat and build the pan slope
My question is: The splice on the vertical pvc drain pipe will go directly through the concrete, do I need to wrap the pipe in 1/4" foam before I patch the concrete? I've got differing and dubious advice on this, hoping someone can give me the final word on this. I live in seattle, so we have big differentials in moisture through the seasons but rarely deep long freezes, if that matters.
thanks in advance for any help on the matter,
jordan
