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. <br><br>

<blockquote type=cite class=cite cite="">I need to drain and winterize my
new sprinkler system and can’t imagine I need to pay someone to do that

manually open each valve, I was told a few years ago that it is easier to
just pressurize the system at the drain valve and then use the manual
function on the controller to run through each zone until no more water
comes out. (FWIW, my system is not that large and has 6 zones.). I
was thinking about rigging something up that would allow me to attach my
compressor and walk away, but found this on Amazon, which seems like a
good investment that would pay for itself on the first use:

. I could save around $10 and just buy a hose to quick disconnect
fitting, but the shut off valve seems like a good addition.<br><br>
I have fairly large compressor, but think it will be more trouble than it
is worth to get air to the master drain valve. Instead, I was
planning on just using my Harbor Freight 8 gal portable compressor.

). My water pressure is regulated to 60 lbs, so I figured
something around this should be sufficient.<br><br>
Am I missing anything? Is there any good reason to pay a
professional to do this job? It seems like a no-brainer to me, but
I’ve been called a no-brainer before.<br><br>
Thanks,<br>
