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)

Filler apertures are high up on the coach and with no threaded coupler. Heavy water hoses have to be lifted and then bent to fit the aperture with no way to keep them in place. This simple device with its own light shutoff valve solves a lot of those problems. The flexible neck goes far enough into the water filler opening to hold the hose in place and then you can remove the hose without having to run over and turn off the water. I bought three so that I would always have one available at home and on the road.

The valve makes the filling easier

Does what it says it will do. Watch the gasket. It can get messed up in there and cause the ball valve to not close tightly. Easily fixed, but kind of a pain.

This is a handy little adapter which makes the job easier and convenient for two reasons. The on off valve greatly lessens the chances of spraying water everywhere or on yourself. The vinyl tube fits down into the filler neck and when added with the metal attachment clip (sold separately) can be hooked to the filler neck and walk away while it fills. Highly recommended!

We have an older vintage trailer and the water fill really needs one of these. We like everything about it except its tendancy to fold or kink and stop the flow. It needs to be watched to assure that there is free flow of the water into the tank. On our trailer the water fill makes a right turn and that is where it kinks. We may modify it avoid this. If your inlet is a straight shot this would be perfect for the job. It is about 9 inches long and made with a 5/8 lead free plastic. There is a control valve to keep the flow speed within an acceptable range. We like this valve control as it keeps waste to a minimum. No over spill if flow is too much, just turn the rate down a little. It does allow for a quicker fill rate as the fill hose can allow air to escape around the tube. The fitting screws onto any normal garden hose. It does the job and makes filling much easier and we would purchase it again if we needed knowing this shortfall on our rig..

Handy for tank water filling

Easier to fill pop up water tank without pressure build up and then you know when its topped off because of overflow.

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

Saw this on YouTube tips and tricks video and thought Id try it out. It works well, especially de-winterizing when were not sure how much fresh water we need to flush the lines and dont want to fill the whole tank.

This product worked exactly as we hoped! We just purchased a brand new camper, and for whatever reason, we could only get about 30 gallons (1/3 full) in our fresh water tank, the water would eventually come flowing back out of the full spot. Used this product today, and we were able to get a full tank! We ran the water at a very low pressure, and I would shut it off every so often and could hear it venting, but nothing came back out! It was also pretty great because I didn’t have to stand there and hold the hose.
