3/4″ 40-60 psi Red Female float valve which can be used on any fountain that uses the 3/4″ female valve. This would mostly be the ThriftyKing CT6. This valve will provide 20 gpm @ 40-60 psi. This valve is a female pipe thread connection so to insure there’s no leaks, an integral o-ring is included (much like a garden hose gasket). Make sure you don’t leave this oring out during installation of the valve or your fountain may overflow.
