In response to Re: new toilet flange fits loosely
The only constant measurement on ABS and PVC pipe is the outside diameter. The inside diameter will vary depending on the wall thickness. If your pipe is thinner than normal then the flanges will not seal or attach properly. Glue is not a filler. It is designed to bond the pipes together, not fill a void. You may have to get and install the proper flanges that fasten on the outside of the pipe.

: My basement (poured concrete floor) was pre-plumbed for a bathroom when the house was originally
: built (~1988). The white (PVC?) waste pipe for the commode (flush with the concrete floor surface)
: has an inner diameter of 4 inches, according to my measurements. I have purchased two
: different PVC DWV closet flanges, whose specs indicate they
: should fit INSIDE a four inch inner diameter pipe. However, both flanges
: (different brands) are very slightly loose when inserted down into the
: existing pipe. When I say slightly loose, I mean that probably just one
: layer of some kind of vinyl tape would make the fit "snug". I am
: hesitant to glue either of the flanges in place, because of the
: possibility the joint will not be air tight. Is there another acceptable method
: of installing the flange into the waste pipe?, or do you think an ample amount of
: pipe glue will adequatelyseal the flange? Any suggestions will be appreciated.
