Good point about the 'air gap'. The rest of the set up is jsut
standard plumbing fittings once the screw-in adapter is in place, just
keep necking down to get to a reasonable size.
One can do amazing things with pieces from the local plumbers parts
bins. I once even built a barrel pump out of standard fittings.
Another was a reel for a 1/4" hose line used to water house plants.
The rotating axle feed was from one of those 'snap-on' hose
connectors.
