Moxadox said:You may need to replace the knife valve (the thing that closes the tanks). They are very simple to fix.
As you will discover, RV systems are delicate and wear out with sitting in storage. They also wear out with use....so I hope you enjoy tinkering, because RVers need to frequently tinker!
Congratulations on your new RV, hope you enjoy it. If you haven't already, you might like to join the iRV2 forum on Tapatalk. You can find out how to replace your grey tank knife valve there. If I were you, I'd replace the black tank valve too, before it decides to go south on you (much worse than grey valve, as you can imagine)!
