Gray tank vent location - 2017 377RLBh
Good morning all, quick question, where are the gray tank vents located on the 377? I’ve been developing a very weak flow from both grays over time, especially the gally tank, when dumping and would like to confirm the vents are clear.
Thanks!

Some units use an 'air admittance valve', most often under a sink. They can 'fail' and not admit air.
A plumbing schematic from Jayco (call them with your VIN#) will likely show what venting your unit has.

Tom, ty! I’m at the vent in the roof. Took the top off the vent and found an old wasp nest looking thing. Trying to pull it out. To wash any smaller debris out, do you know if it’s ok to pour water down the vent? Will the water I pour in end up in the gray tank? I’m hoping to wash out anything that may be lower in the vent that I can’t see.
Thanks!

You should be fine pouring water in the vent and yes it will end up in the tank. I wouldn’t go to crazy with the water just in case the vent pipe isn’t glued as good as a drain pipe

I pushed a water hose down mine, with water off just to see if it went to the tank. It did. I have heard of the fitting not being joined. permanently at the tank.
