RecPro Fresh Water Fills Cap Only, 222PW-A - Polar White or Black Cap and Strap (White) - Made in USA Review

As a new owner of an RV, I was in search of an efficient water system upgrade. As a result of using this product, I found that my water system is smoother and my water tank is filled in no time. The installation is straightforward and it fits the description provided. The only con would be the slightly higher price point, but it is worth it for the quality upgrade in automotive plumbing parts.

The strap had a different shape where it was attached to a solid frame. So I had to drill a hole. Didn't know they would be different. Mine was rectangular and this one is round.

The lid was very tight on the water inlet. The plastic parts that attach the cap to the filler tube do not fit into the filler tube holder. You are unable to craft a closed seal. There are two types, but neither fits the stuffing tube and only one fits this cap. Why is it even in the packaging because it doesn't fit or fit on the lid. Inside the lid there is nothing like gaskets so as not to miss anything, fine dust can still get in through the hole in the lid.
