    Works great!

    Overall it works very well. The only small problem that I have with it is the mounting hardware needs to be more stable. There is only one screw in the mount, so if you bump the float valve it uses the screw as a pivot point and moves either direction.

    This is not an over all bad Auto top off, I have had it run and not stop a couple times not sure why that is. It is not worth the price, many other out there
