I'm remodeling my bathroom.... The bathroom has been remodeled before, and they added a 2nd toilet and a shower to the drain line in the bathroom... Now I don't want the 2nd toilet and the shower.... is it okay for me to simply put a pvc cap on each of the pvc pipes that i wish to not use anymore... Or do i need to chip all the floor out and rerun the drain line to pick up just what i wish to use?...
