Important maintenance item

Something to keep in mind for anyone with a water tank mounted inside their RV. While filling the tank at Murphy's Point early this week I noted that the vent on our Valterra gravity fill valve didn't seem to have the same "noise" of venting air. The campsite hose was leaking in multiple places so I was concerned trying to keep the leaks under control. I stopped filling due to the problems with the campsite hose and I'm glad I did.

My tank was full to the top, the 1/2" vent line that is secured to the back side of the Valterra valve with a Pex type crimp ring had sheared off completely. If I'd not stopped, I would have caused a flood under the bed of our trailer. We store nothing under the bed, no reason that the hose had been dislodged or bumped by anything. All of the hoses are secured with gear type clamps, perhaps the crimped on Pex type fitting applied too much force to the valve and the plastic gave up after a few years.
