The Float valve/autofill can be placed inside a large pond skimmer or on the edge of a pond to help keep a uniform water level that otherwise could lower, due to evaporation or if a leak should develop.

Protects your valuable pond pump from overheating!

This autofill easily attaches directly to a standard male pipe thread garden hose connection. Package includes containing screws, washers and nuts (if you attach autofill to a skimmer).
