We have a cimmaron toilet (low water fast flush) It has been clogging too often. There are two people in the family who are "culprits." Even so, the toilet should flush waste. We use a plunger and it most usually works. However, we recently had a plumber auger it and auger it and finally clear it up. What is causing this? Shouldn't people be able to use their toilet without fear of clogging it up?? It is not the main line as all drains empty beautifully.
