Try the McMaster-Carr plastic cam-and-grove hose couplings. Works great!

Does anybody have ideas or a solution in place for quick disconnects for
piping to the pump in the pond? Mine clog or need impeller replacements
often enough that having to unscrew it from several feet underwater is
getting real old.

Thanks.
