Question Electric air pump for blowing out water lines?

I will be winterizing our Wildwood soon, and want to blow out all of the water lines, and use some anti freeze as well. I don't have an air compressor, but I do have a high volume air mattress pump made by Coleman. It plugs into AC power and puts out a lot of air. I think it would work to blow out the lines.

Any thoughts?

Does it have a standard tire valve fitting on the hose end?
Does it pump max 30-40 psi?

I don't think that will be sufficient. It's not likely to create more than about 5 pounds of pressure.

IMO, it should work fine if you can adapt the output to the city water inlet and can make an adapter for the water pump; both airtight as the pump's output pressure might be on the low side.

Rather than take a chance though, (since you are going to put antifreeze in it anyway), I suggest just buying a winterization kit and put the antifreeze through the water pump to begin with.

Don't forget to flush the toilet, burp the city water check valve, open the outside shower faucet, and run the "Pink" through the holding tank flush system if you have it.

Herk, can you explain about burping the check valve? And what about the holding tanks. I don't want them to sit over winter dry so do I drain them and add antifreeze?

Belt and suspenders? If you will be using antifreeze, blowing out the lines first isn't really very useful.

I disagree. I blow the lines to remove as much water as possible then add antifreeze. Removing as much water as possible decreases the chance of diluted antifreeze.

Actually it is better to get the water out so you do not dilute the pink stuff, you will use less pink stuff too as you do not need to flush with it, just fill the pipes.

Once you drain the tank and open the low point drains, most of the water is gone. Most of what is left gets pushed through the lines ahead of the antifreeze. The amount that the antifreeze will get diluted is negligible. Going through all that effort to save half a bottle of antifreeze hardly seems worth the trouble.

I agree with Great Horned Owl, for $4 or $5 a jug and the time this takes.
I get a case and let it run. (I will pour a little extra in the P traps)
Then I will open ALL the taps and drain valves.
