Review on 🚰 Camco RV Water Tank Filler with Shutoff Valve: Efficiently Fill & Prevent Backflow | 5/8" Tube - 40003 by Justin Dorsett

Excellent. I would never fill up my tank without one of them. We bought our very first camper and it was one of the things I saw on the What Other People Buy list when I bought wheel chocks. I'm so so glad I bought this. When I filled my tank for the FIRST EVER time, I hooked it up to a springy drinking water thing and stuck it in the tank and I didn't have to hold it or anything. The elderly gentleman next to me, who looked like he had been away for a while, hadn't. He stuck a hose down the filler neck and thought he was holding it. He let go and the hose let go, and behind the spring at the blue drinking water dispenser he whipped the threads of the hose straight at his cell. I don't know if he crushed it but it definitely made a decent bang and he looked embarrassed. Thank you Amazon for helping me buy something truly amazing on the fly!
