We've been having problems with our master bath toilet clogging. Seems to clog much too easy. So I removed the toilet and found a sandy substance building up in the drain pipe. I scraped it out but I'm not sure how far it extends down the pipe since it bends about 6" under the floor.
Our hall bath toilet is also having simliar issues although I haven't removed it yet.
Any clue what could be causing this build-up? Is it hard water or something?
Thanks - Jim
