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.

Added this into the kit this year for the truck camper and glad I finally did. Its cheap and just works. Sure you can just stick in the end of your garden hose into the tank but just get this. Keeps everything much cleaner and also just easy with the valve added in.

Works as it should

Helps filling the tank

I should have bought this sooner! Makes filling fresh tank way easier and you can push tube end inside to where it stays and you can go do something else while filling!

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.

Handy little gadget. Makes filling the water tank super easy.

Needed this for my RV fresh water refill. It was cheap, but it worked great. Highly recommend
