Now if I can just get a parts list for a Keg and Carboy washer I will be Kicking@$$...
This is super easy if you have the pump. Here's what you'll need:
(1) 1-1/4" Lead Free Brass or SS Coupler
(1) 1-1/4" to 1" Lead Free Brass or SS Reducer Bushing
(1) 1" MIPS to Slip CPVC Adapter
(Note, the three above parts can be replaced if you can find a CPVC 1-1/4" FIPS x 1" Slip Adapter, I haven't found any personally.)
(~3") 1" CPVC
(1) 1" x 1/2" CPVC Reducer Bushing
(~6-12") 1/2" CPVC
(1) Homer Bucket With Lid
(1) Carboy Holder
Simply build the riser, cut a hole in your bucket's lid, drop a carboy holder on and you're done. There's no need to use 45* elbows to bring the pump's output to the center of the pump. I've found you can get the output to fit in the center of the bucket without such fittings.
A keg washer usually entails a cross that is then connected to high temp 1/2" tubing attached to keg quick disconnects. If it were me, I'd cross with a 1" CPVC and reduce from there to maximize flow and pressure. This allows you to wash the two tubes within the keg along with the inside of the keg.
There's other ways to do it, with different fittings, but I prefer having a 1" input for as much as possible since it maximizes flow. You could also go straight to 1/2" CPVC from the 1" FIPSxSlip adapter with a 1" socket x 1/2" slip CPVC bushing. You also have the option of using the provided reducer (with the pump) that would eliminate the need to deal with 1" CPVC and reductions entirely, but it will reduce the output from the pump immediately.
