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)

This is a very simple but very useful device that does its job and does it well. It's an attachment to a water hose that helps you fill a water tank via a "gravity fill" (i.e. non-pressurized) port. It does two things: (1) extends the hose into the pipe behind the gravity fill port, reducing spills, and (2) provides a useful valve to regulate and stop the water flow once your tank is full. It does both well; I have no complaints.This device isn't strictly necessary for filling your water tank, and I originally didn't think I'd need it. But now that it's solved the problems it's designed for, I can't imagine going back to life without it. For example, filling our water tank used to be a two-person job: one person to hold the hose to the fill port and watch for overflow, and another to hover over the water spigot (which might be some distance away) and be ready to turn it off at a moment's notice. Now the water flow can be turned off quickly via this device's valve, and we no longer need that second person.

Works great. can be used to rinse areas that are hard to reach.

Perfect little attachment to easily fill my water tanks. Use it every time.

Bought this for filling our fresh water tank on our camper. The long nozzle is nice, and the ball valve for shutting off at the camper is very convenient. I don’t know how well this will hold up as it is completely made from plastic, but, for the price it was worth a try.

Works well, valves doesn’t leak which is all I ask for.

This makes filling the camper so much easier. I'm glad that I got one.

A lot less mess feels quickly the shut-off makes it excellent

I was having issues filling my rv tank because it wouldn't vent. I use this and have no issues anymore. Price is right. Easy to use. Build quality is decent.
