I'm re-doing a 4x5 1/2 bath in tile and radiant heat. (BTW, I've posted this question to the John Bridge forum, but I came here to look for more input.)
Issue 1:
The bathroom is on a crawl space and has a slight slope to it. From the entry to the opposite wall (5ft) there is a loss in height of about 3/4 inch. I plan of leveling the floor either with shims or with floor leveller (opinions welcome), but once I level the floor, the flange will be slightly out of level.
Issue 2:
The cast iron flange is toast. It has no collar all. Because the flange height will have to be raised anyway (I'm going from thin plywood and vinyl to 3/4 plywood, radiant cable, ditra and tile), I was hoping I could use one of those Twist 'n' Seal units (PVC or new cast iron) screwed to the floor, with or without spacer(s). My hope is that there will be enough "wiggle" room that, together with a good wax ring, the thing will be OK.
Since there's an elbow about eight inches down from the flange, I'm not crazy about snap cutting the pipe from the crawl space.
I'm leaning toward the cast iron twist 'n' seal. Any thoughts?
