Jim,
I rigged up an adapter like that many years ago
and I have been using it every time I need to
winterize a sprinkler system, summer home or
other similar tasks. I usually run a garden hose
from whatever drain valve I want to the
compressor. I use my adapter at the compressor
end of the garden hose to connect to the air
supply. I have enough garden hose that routing
to the drain valve isn't really a problem. I
don't need a lot of air pressure, but I blast a
lot of air volume through to push the water
out. My main garage compressor is my first
choice, but I have used a smaller portable one
and it did OK. As for purchasing that adapter, I
would do it. I don't know if such a thing
existed when I made mine. Twenty bucks would be
worth it to me for the convenience. Of course,
if you have the pieces already and you don't want
to wait for an adapter to arrive, making it would
also be a reasonable thing to do. I don't have a
shutoff on mine and I don't really miss it.

I rigged up an adapter like that many years ago and I have been using it

similar tasks. I usually run a garden hose from whatever drain
valve I want to the compressor. I use my adapter at the compressor
end of the garden hose to connect to the air supply. I have enough
garden hose that routing to the drain valve isn't really a problem.
I don't need a lot of air pressure, but I blast a lot of air volume
through to push the water out. My main garage compressor is my
first choice, but I have used a smaller portable one and it did OK.
As for purchasing that adapter, I would do it. I don't know if such
a thing existed when I made mine. Twenty bucks would be worth it to
me for the convenience. Of course, if you have the pieces already
and you don't want to wait for an adapter to arrive, making it would also
