What are you trying to do? Maybe we can help beyond what was said above if we know the purpose.

I did find a brass hose bib with a ball valve at home depot that we use on the backwash for our pond filter. Much less restrictive. This allows us to hook up a hose and water plants when backwashing. This is on a small submersible pump that only moves about 1/4 the volume as the pool pump though.
