We are in a 30 year old house on a septic system. Recently we have been noticing septic odours from the upstairs toilet area and the kitchen sink drain area. I have read a lot about “traps” but I don’t understand how a toilet can smell if the bowl is full?? Please educate me and offer some suggestions. Thank you.
Maybe you have to reset your bowl with a new wax ring. My tank would smell out the vents on roof so i dug it up and put in a trap and it is okay now. You could have a cracked pipe in the wall and if plumbing is short of vents it could be syphoning the traps and let gas in.
Hi – thank you for your reply. The upstairs toilet – the one I am noticing odours from – was just redone with a new wax ring. It hat rotted away teh fibreboard floor below it so we had to put a new piece of plywood to raise it up. Now with the new positioning and new wax ring, the toilet does not wobble or lean, but the bathroom now smells….any thoughts??
