Drain Fitting conversion? Recommendations?

Jabba · 07-11-2003, 10:21 AM

Hi all, I've tried without much luck so far to find a way to convert to a modern fitting. Our '55 has a straight 4" (I think) MPT nipple to screw the drain hose on. After one use, I decided this is NOT the way to go. Has anyone seen a 3" or 4" FMP to a modern Bayonet or whatever connection? I don't want to alter (if I don't have to) the drain fitting, I hope there is a screw on adapter? Am I just overlooking them? Also what are the recommended fittings regarding style?

Jason,

I would reccomend that you find a PVC connector that will mate to the factory pipe, then add a small piece of PVC to it and a Standard bayonet fitting to the PVC. You could go with a Valterra or if you want to stay Airstream get a Thetford one. Then you have a cappable connection (DOT required) and can eaisly attach a hose.

Was yours a "park model"? It is very possible someone modified yours in past, as I thought all airstreams had a quick disconnect.

I'll look into that approach too. It wasn't a park model, that I know of. PO mod I believe.

4" threaded fitting?

perhaps a fire hose fitting might work.

then you could adapt it to a standard "stinky slinky"

after building my pnuematic spud gun there is nothing you can't build out of pvc fittings.

find something that threads onto your trailer then find something that will fit your preferred hose setup. then go to home depot and start shopping.

all you'll need is a can of glue and your imagination!
