My toilet, a Dometic 320, has suddenly started acting like there's a vapor lock when I flush it. I step on the pedal and it burps and sometimes even burps so bad it splashes some on the floor. What is...
As mentioned in op, I had the tank emptied when it first started and I don't leave the valve open. I have someone coming to check out the vent and/or the pyramid. Praying it's the vent! Thanks for all the suggestions. Will report back with solution.
