Review on RV Trailer Marine Gravity City Water Fill Dish Check Valve - Valterra White by Joseph Adaymiln

I thought the gravity water cap was included with the purchase (the one in the picture) and I didn't receive it with my order and had to order it. It was exactly like the picture (except for the gravity coating) but it was a more complex replacement. Our 2001 Prowler's outlet would not thread into the new cap and we had to replace the fitting. If it would spin, we could replace the cap in about 15 minutes.
