Winterizing / Attachment To Air Compressor To Blowing Out Water Lines

I have a question about the "right tools for the job" when blowing out water lines to winterize.

I use the Camco plastic blow out plug:

And then I try to use one of these attachments that came with the air compressor. However, none of them fit just quite right. The black one is a little too big (so some of the compressor air escapes around the edges). The blue one is pretty close but I need to hold it right on top of the hole in the Camco plug (so again, some of the compressor air is escaping around the edges).

Is there some other attachment to the air compressor that I should be using?

Thanks!

You should have purchased one that has a built in air stem in it. Then you can clip the air nozzle from the compressor to that.

X2 Ford Idaho....you beat me to it. Just be sure to NOT go over 30 psi when blowing out lines.

OP here again: A-ha. So it sounds like I got an el-cheapo blow out plug. I should have gotten a brass one that has a stem in it almost like a tire. Then I could use the attachment on the air compressor that I use to inflate tires. Please advise if that's NOT right. Thanks!

I got an el-cheapo adapter (about $1.89) from Wally World's RV section that had a Schrader tire valve-size on one side and a male hose-thread on the other. I use the tire inflation thingy on the compressor hose and it fits the Schrader-like connection just fine.

With the compressor tank at 120 psi and the output regulator set for 30 or so, I can blow most of my system out without the compressor coming on again. Of course, the water heater is out of the circuit with the bypass valve. A cup full of the pink stuff in the sink drains and the shower drain and we're set.

Three winters so far and no problems. Bear in mind that a really nasty freeze here is down to around 25F and doesn't last more than two nights. Daytime highs are rarely below about 36. A harsh climate it's definitely not, which is one reason we live here.

Or you can use a small piece of tygon tubing between blow plug and your red air adapter.

This is the one i have used. It actually has the quick connector for the air compressor rather than a tire valve. I also purchased an inline filter to keep any oil, dirt, etc from the compressor out and attach that to my 90 deg elbow so it hangs down not out.

I use the same as the photo below except all I have is a brass water hose
fitting that's screwed directly to a male air quick connect.
Like the photo with the center stuff missing....

Since my water pressure regulator is typically set at 40 I don't
worry about air pressure more than that.
I usually have a faucet open at all times during the blow out so I don't
even use an air regulator. Just plug on the air hose and stand back.
That open water heater drain has sprayed me too many times!

If your "compressor" has adapter plugs like that, I'm concerned that you may be talking about something to blown up air mattresses and floats. If so, that's not going to generate enough pressure to blow out your lines for winterization.

I got my compressor quick connect adapter that screws on the water inlet at Camping World on sale for $8 or so.

Anyone who ever used compressed air to winterize will NEVER go back to the pink stuff again.

I use the same Camco winterizer attachment the OP asked about with this tire valve air filler from my compressor with no issue?

Gosh.. y'all got rather fancy there with your blow out devices.
Me? I just bought the $1.59 blow out plug you screw into the city water outlet. It works great and you cant beat the price!
I like the KISS method :O

OP here again: This is the compressor I use. Sure, it doesn't have enough guts to fill the tires on a jet (I say that because I'm in a hotel room looking out at the LAX landing approach right now). But it has plenty of oomph to blow out water lines. Actually the 3rd picture shows the included accessories.

We have a winterizing camping trip every year in November with friends. We blow the lines out with an air compressor, put the camper away for the winter, fly to Fort Myers and tow the beach chairs with this!
