2021 Coachmen leprechaun 300bh Ok so i have been looking at a lot of things on here and I cant seem to find the right answer. ( Preface, my motor home is a bit off level to the front) So first off I can turn on my sink faucets and run them for a good three minutes and no back ups when I turn them off there is a significant amount of gurgling coming from my walls. From the looks of it that is where the vent pipe is located. I was taking a shower and water was draining and then all of the sudden nothing, i mean not a drop more. i went to the roof to see if the vent was clogged and when i looked in there i could see water and it was bubbling. so i opened the valve and it all went away. so im not sure why water would be going up the vent pipe. I'm a first time RVer and need some help.

Cmccain, What valve did you open? Is it possible that the gray tank was full to the level of the shower tray" I don't know Coachman well at all so maybe someone with more familiarity can be more help.Matt

Air! Drains for a while and stops indicates a plugged air vent.

With my Bigfoot truck camper, if the camper is lower on the passenger side the shower doesn't drain properly, and the water from the kitchen sink sometimes "washes" the bathroom floor. There is very little drop from the shower base to the grey water tank, and the piping is such that this happens. I just make sure that the camper is level, and there is no problem. I would try levelling the coach, and see if that helps.

Am I understanding correctly that when you went on the roof, that the vent pipe was full of water? And...when you then opened up the grey tank drain.....how much water came out? I.e. Was it just a few gallons or did it seem like the grey tank was full?And... last question....is this a new issue or did it just start? Or is this the first time you used the rv?
