Thanks to this thread, I went ahead and bought Marks Keg/Carboy washer and have used it several times.
1) Does a great job on the cornies as well as the 6 gallon glass carboys. I have not had anything so stuck inside the carboys that the washer with oxyclean free could not clean..yet
2) Great pump- plenty of volume
3) I had absolutely zero issues with carboys/cornies falling. Seems fairly solid
1) Cheap flimsy hose barbs for the connectors- I can see how they would break, bend and contort
2) As others have stated, no drain for the liquid- lift and pour- I will rectify this myself.
3) Relatively shallow basin- Would be good to have a bit more volume, but may not be feasible to keep manufacturing costs semi low.
Go with some higher quality pipe fittings for attaching the quick connectors and possible a "T" to do both sides.
I seen a need to have something to clean my beer lines and didn't want to have more tools than what I could store.
I picked up a few 1/2 pvc caps at home depot along with a 1/4 flare to 1/4 MIP as well. I drilled the cap for the 1/4 pipe (12.2mm 1/2drill will probably be fine) and tapped.
Threaded it onto the extension that comes with the pump at the top and hooked it up to the beer lines. Took a 2 ft section of 1/2 silicone hose and pushed it over the end of the perlick tap to return the liquid to the basin. Turned it on and let the oxyclean flow- Works great!
I will rinse it with water a few times, but I don't have to have a separate cleaning unit for my taps.
Part# for the flare; 17000080
Part# for the cap; Store SKU # 29423 (verify as I didn't remember the number)
I think the total cost on this was around $8-$10.00 including the silicone tubing.
I like to make as many things as I can multi-purpose. I just don't have the room for all the equipment that we all would like to have.
