Camco RV Water Tank Filler with Shutoff Valve | Quickly and Efficiently Helps Fill Your Water Tank and Eliminate Line Backflow | Features a 5/8 Tube (40003)

Works like a charm

Most newer RV’s have a cap opening for fresh tank water fill, this spout threads on to fresh water hose & slides into hole, also lets you control water fill.

I couldn’t get water to go down my gravity fill without this! Now it’s easy and worry free. I have a city connection, but this is way more easier to use. If you own an RV with a gravity fill location, you will want to have this with you!!!

Would buy again if needed.

Oh my gosh. I bought this just as a recommendation for first time RV buyers. I didnt need to use this for quite a while because our sites had all had water. Today.. we pulled into our campsite and it did not have water. This helped to fill our fresh water tank tremendously

If you have an RV or travel trailer this is one of those simple little conveniences. Super inexpensive just get it!

I use this anytime I pull up to a fill station and the spigot is on the opposite side of the camper from the inlet. It allows me to shut it off at the inlet instead of just dropping the hose and running to the spigot. Makes for a cleaner fill.

Ordered a while back and still have not used. Still in same package but it looks to be made really well. Kept in camper incase needed.

Works good but something has to support the hose while filling or the weight will kink the tube in the trailer fill

Makes it easier to add water to tank on camper dont have to stand there and hold hose to fill
