This is something I probably should know, but don't. We have a new to us 2000 Winnebago Chieftain 35U. In the water/sewer bay is an external shower. The faucets seem to be made by Phoenix. The outflow connector where the shower hose screws on in kind of an "L" shaped thingie... part number 91L5 VAC.
The problem is that when the shower is turned on water flows from the bottom of the valve as it should, but there is also a small hole at the top where water also comes out, flooding the bay. To me this is not a good thing. Is this just a bad part that needs to be replaced? Should I plug the hole on top?
Picture link below. Tried to insert pic, but didn't make it. Thanks for any thoughts.
yep, it's a defective $5 vacuum breaker. It is threaded & screws in. No need to replace any other parts. Just put a small open end wrench on it & screw it out. Take the part to RV store & replace. I also had one of these go bad in the shower in my RV. Same symptom, squirts water out the hole. It went bad over the winter. later...dan

I would think the spud pointed up is the more common install. I can't recall ever seeing one protrude from the bottom as yours does. If the ball indeed floats then up would seem a better way to go.
There is a small ball check valve which is supposed to block the air hole under pressure and allow air to enter when pressure is removed. If the spud freezes the short pipe can crack and spew water which deflects off the hole area and make it appear to be the hole leaking. Lime, crud, etc. can also prevent a good seal.
While it would be a bit of a project, it can be flipped by reversing the hot & cold connections & reversing the handle inserts.
