ok, the subject is pretty much covered, and beaten to death.

one more final word,
just this morning I examend the water flow coming out of the torch
return hose.

as a reference: it appears the flow/volume is about same as I get out
of my fridge water dispenser. may be slightly more.
keep in mind this is not the full flow of the carbonator pump because
it is "T" off (as mentioned earlier.)
if you think about the small passages that are in the torch head , it
is plentyfull water.

good luck
