Re: Help! Plumbing issues!
First if it were the septic system or the drain lines adding water to the bowl wouldn't help. I suspect either there is a missing, clogged, or improperly installed vent, the tank is not filling enough or it's an older low flush toilet. Try holding the flush handle down when you flush to empty the tank. Check to see if the tank is filling to near, but not over, the overflow tube in the tank.
