Not when you're filling the tank with a 5/8" hose. You must reduce the flow to less than a third, since the area of a 3/8" diameter hose is about 1/3 the area of a 5/8" hose. It's actually far less than that, since the air not flowing out of the vent is flowing against the water you're trying to put in.sch911 wrote:Blacklane wrote:
Apparently not. I have a 1" hose into the tank and a 3/8" vent connected to a lockable fill port on the outside of my camper.
Sounds like you have a blockage in the vent hose. The 3/8 hose is more than enough to pass the air out of the tank if functioning properly.
We put a 5/8" hose end into our fill on the side and walk away until water runs out, it goes in maybe 3 inches, the vent works fine to get the air out.
