Mumusuki Auto Water Filler with Ball Valve, Plastic Nonelectric Water Level Controller Adjustable Tube Float Valve Kit for Aquarium Water purifiers

Worked well for my use case. Used as a backup shutoff if my refill sensor dies amd begins to flood.

Set it up in my sump and hooked right to my RO system for auto top offs. I had to trim the lip of the black plastic on my 40b for it to fit over. Very sturdy and the tank clip and adjustable side are one piece. I say that because I have broken one in the past by over tightening, I think it was the eshopps one. Float is good and no leaks so far. The connection is the screw on type, not the standard push in. I have had issues with those leaking in the past but so far no issues.

It’s too short to stick into a sump. The plastic is cheap and it would be great if it was paired with a pump that automatically turned on when the water level hit a lower level. I’m still working on figuring out how to get it to work without making it look stupid.

Simple setup and plenty of hose with it

The ball valve will not close no matter what pressure I turn it down to. Unfortunately as some have mentioned I had to modify the hanger so I can’t return or exchange. Just a heads up.

avec une utilisation frequente depuis plusieurs mois , sa fontionne encore a mervielle.Je recommande ce prodhui

The product mounts to the glass allowing easy adjustments and fine tuning. The product has a basic float.

Waited weeks to get. Nylon screws don’t thread at all. Unusable product to even see if it works at all. Would’ve been cheaper to go to local hardware store and build myself. Extremely disappointed on purchase from marine sources. In addition, what’s the point of buying for a saltwater supply product and everything is plastic except one metal screw? Let’s not forget about the several long strands of black human hair included in my purchase.

as advertised

Works great
