Quick and easy tank blowout connector

I made this in about 5 minutes and $2. It allows me to set my compressor to 30psi and connect it to the fresh water supply to blow out all the lines.

I used a compressor quick connect, a dollar store quick hose connect and a 1/2 inch drill bit.

Thanks for the idea, going to make one myself. I had something rigged up last year but can't find it now.
Here we use the 5er year round but when I know it's going to get real cold I blow out all the lines. Putting RV antifreeze in here is a waste of money so the air is our best option. Thanks again for the idea.

I bought two of these last year. One had a air chuck and the other a tire valve stem. I think I paid $9 for the two. They can be used with either kind of compressor. I doubt I will ever use either one as I live in SE GA and we don't winterize, but good to have just in case.

Had brass quick connect got a brass threaded fitting that fit both the waterline and the quick connect for under $3 .

I would be more concerned with blowing water line joints with campground city water than with air. I use a pressure regulator at 40 psi with city water with no problems so have no worries with air at 40 psi as well.

I made my own,,, Male hose connector on one end,,, air chuck on the other,,, it is about 3 feet long,,, made with garden hose,,, and a gas valve in the middle,,, I like it because I can stop the flow of air any time I want !!! And it also gives the compressor a chance to build pressure back up !!! Of course I get the DW to help !!!

The only way, I've found, to make sure the pump is protected is to fill it with antifreeze.

I am sure the antifreeze left in the pump & the faucets is better than dry !!!
As for the seal in the stool also !!!

I tore apart an old air compressure and took the fittings and the the pressure regulator off and made one that will screw in to my hose connection that has the regulator and pressure Guage on it works great that way i dont have to screw with my compressure and have every thing right there

Very handy. I also made one similar to yours. I use it to blow out the pressure washer, too.

The first time I blow out the lines I didn't think about the water pump. I was lucky that it only broke the glass bowl on the filter in line before the pump. I replaced the filter and everything was okay. Have anyone found a way to make sure the pump is cleared?

I use air to blow out all the lines, pull the rod on the water heater, etc. Then, if the temperature is going to get below 40į I leave a small ceramic heater/blower that puts warm air into the open cabinet doors to keep the pump from freezing.

At some point during every day you suddenly realize nothing else productive is going to happen the rest of that day. For me, it usually occurs around 9 am.
