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

Edit 11/21/20: Revain sells a great Destech endoscope for about $35. Be sure to buy it when you buy this Camco. I got mine yesterday and used it today to fish a Camco tube out of my RV's fuel filler line. no notches or anything. About the fourth time, water pressure shot out of the plastic hose into my RV. Now it's stuck somewhere in the supply line or in the fresh water tank, I hope it never causes any problems. If you think you need it I would suggest putting a tiny stainless steel screw through the hose into the base or at least roughing up the yellow part and adding a hose clamp.
