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

Does its job, saves sprinting back to the water spigot to turn it off when the tank is full. Price is great, and minimum packaging to throw away or recycle. Hurray!

I was having trouble filling my fresh water tank until I bought this product. I highly recommend getting it if you use your freshwater tank on your RV.

Great for filling your fresh water RV tank. These are needed for filling travel trailer water tanks, as filling too quickly causes the fill tube to overflow, making it appear that your tank is full. Then when you arrive at your destination the tank is soon empty, because it was only partially filled. Although there are easy ways to verify the tank level before you go, such as checking the tank monitors, visually inspecting the tank underneath, there are countless posts on the net of people thinking their tank was full, or being unable to fill it because it overflows. This is because you need to slowly fill them to allow air to escape. This hose allows you to restrict the fill rate with the valve on the nozzle, plus the tube diameter is smaller than the fill tube, allowing air to escape. Well worth the low price for me.

A simple idea that eliminates spills while filling RV water tanks. Without this tool, it took two people to fill the fresh water tank in our travel trailer. The inlet opening was not large enough to hold the water hose nozzle in place while filling, meaning that someone had to be at the fill port to hold the hose and someone else had to remain at the faucet to turn the water on and off. This device extends into the water input port on the vehicle allowing you turn on the water at the faucet. When the tank is full, you can turn off the water at the nozzle before returning to shut it off at the faucet. This makes filling a water tank a one-person operation.

Worked great for filling the fresh water tank in a rv.

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.

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.

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.

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