I have a question regarding plumbing a shower drain. In my house the drain
to the shower is a typical drain similar to this drain
except that the threaded portion does not extend right to the bottom.
Instead the bottom half is "smooth" and somewhat tapered to around slightly
less than 3".
The original installation of the plumbing transition from this piece to the
discharged PVC was simply done by having the pvc pushed up against the
bottom of the shower stall around the end of the "coller" and held up
forcably that way by wire. Obviously not the way it is supposed to be.
This never has caused a problem as the shower is hardly ever used (it is not
the main shower) and the amount of water draining out of it wasn't a
However, the other day I pored about 3 gallons of water into the shower from
a bucket. That, apparenly, was enough water to back up from the trap and
spill over the top of the pvc before it could all drain out. Leaving a
puddle in my basement. That begs the question, how does one transition from
the smooth mettle of the shower drain to pvc? I tried one of those rubber
boot things that has the hose clamps on the top and the bottom but that wont
work because of the "Slight" tapper of the shower drain (and the extreamly
small amount of space available. How is this done?
