RV water spill - check valve fix

After 2 failed attempts to keep the fresh water in my RV tank from spilling on the ground, I installed a check valve to see if this will work. I was losing 3 gallons of water just from sloshing around and leaking out the gravity fill opening while driving. Dang, that's an extra shower and 4 toilet flushes wasted on the road.
