: just roughed in a bathroom in the basement,all PVC, and put the concrete back down. my question is the toilet flange, i really didn't want to use PVC cement to attach the flange to the closet bend in the event i need to replace it one day, which would entail busting up the concrete again. are there any alternatives for attaching the flange, such as silicone, or some other type sealant? comments and suggestions welcome. Thanks
You shouldn't have to change the flange but if you do you can cut the top off with a sawsall and notch the collar and split it off with a wood chisel, or use an interior glue flange. If you don't use pvc primer and cement you can get sewer odor even if you don't get a water leak.Remember to anchor the flange to the concrete so the flange doesn't break.
