Bought a new (to me) 90 westy syncro
Running through the systems, I noticed that the sink faucet allowed
outside water to run regardless of knob position.
Bought a "new" faucet assy from Bus Depot and installed it. Same issue.
Faucet works fine on internal tankage but when you hook it up to
external water, the faucet cannot shut it off.
Here is the really strange part.
I took the replaced faucet and blew into the feed for external water
and the valve kept me from blowing  through the faucet when it is in
the off position. I am sure that I installed the new faucet because
the wiring harness sheath is much longer on the new one than the one
I replaced.
I did notice what MIGHT have been mung on the water threads of the
replacement faucet.
Is there something I overlooked or did I get a bad faucet... or am I
in some parallel universe?
