Folks: We are in california and moved to this house last year. Since then we are observing frequent clogged toilets (3 of it) and bathroom sink. On one of the toilets i changed wax ring. But before I call plumber and pay him by the hour, I would like to get educated on this subject. So far I have read that 1. Toilet Paper 2. Constipated Kids 3. Vent I am suspecting more of vent issues but would like to get more thoughts and ideas. Your help is appreciated.
