Gray Water back up

Anyone else have the sinks backup in the bathroom and the kitchen before the shower backs up?
Usually in other coaches when the gray water gets full the shower backs up. Mine has the sinks backing up. Strange to me

Our 2015 30DS behaves the same. Never understood, nor put much thought into why the shower doesn't show signs of a full grey tank before the sinks.

Gray Water back up

Yes, I had that happen on a sunseeker. The problem was a bad air admittance valve under the bathroom sink. I still am not quite sure I understand exactly why.......but I replaced the valve when grey tank stink was coming in and it also solved the water backup issue.

We had that happen shortly after buying our 30DS, and is was caused by construction debris in the "p-trap" under the sink.

Our shower backs up when the bathroom grey tank is full. We've never filled the kitchen grey tank full, but I would expect it to back up in the sink as there is no other exit/entrance to the grey tank. Except the roof vent and that is higher than the sink drain.

There is only one grey water tank, shared by both sinks & the shower. When it's full, it will normally back-up into the shower, because that's the lowest point.

If people have water backing-up into the sinks, but not the shower, it's due to something other than the tank being full.

Our trailer has two grey tanks, and two 3" drain connections. One 3" connection also services the black tank.

Sorry, my mistake. Since this is an FR3 forum, I assumed you had an FR3.

Well my fault too - assumed just a Forest River Forum. I will look closer next time.

Gray water back-up

We have the same problem- gray water will back up into the bathroom sink when we shower.
In Goshen we had the Air Admittance Valve replaced because of odors under the sink cabinet. Prior to that when the gray water backed up it would be into the shower. Now it backs up into the sink. Of course it didn't do it until we were two days away from Goshen. Would love to know what causes it.
