Malida Auto Water Filler Power Free Water Level Controller Auto-top-Off Automatic Marine Aquarium Water Changer with Float Valve, Vacuum Water Flow Regulator and Controller Perfect for Adding Water.

Works well!

Hooked up to my ro system to my reservoir and it worked great kept me from flooding my basement. Fits well to a 32 gal trash can or anything similar. You can adjust the float level to an extent.

Will hold back hose pressure no problem

Great quality easy to install

Installed this in my console humidifier, connected it to an abaondoned ice maker line in the basement and VOILA! The humidifier stays full, the floor stays dry, the collie stays static free and my back stays healthy.

I am using this to maintain the water level in a decorative fountain. I am only using the float and the valve due to space restriction. Does a great job.

I just made the purchase and installed in an aquarium sump. So far it looks good and comes with a few 1/4” connectors, valve, and tubing. You can adjust the height of the float and the float itself. The height adjustment takes some finesse, and the float adjustment uses a Phillips screw. Use one of the included connectors on the float, then your tubing to the connector. So far so good.

dignity! Using this in a 35 gallon water storage container. My RODI system fills the tank so that I can mix saltwater for my reef tank and this auto water shutoff works like a charm. The float can adjust up or down about 4-5 inches, and the float angle can also be adjusted to further fine tune max water level. I likes! I am very excite!
