Once you drain everything else there's not enough water left in the pump to freeze and do any damage.

Yup and I run the water pump dry for a few seconds..

This has been working for me for years. I just can't stand the pick stuff.

It hits sub-freezing temps here with below freezing for days at a time.

Don't all RV water pumps have check valves in them?

a wetvac as mentioned ealier might help with this too.

Did that For years and it worked fine , untill it didn't .trouble is some pumps have a check valve built in and some have an inline check valve just before the pump . The toilet valve is usually the low point in the system . After blowing out the lines what ever is left settles back to that low spot and running a water pump dry never gets it completely dry . Now keep in mind this is all temperature dependent . I see sustained sub-freezing temps , other locals won't likely have a problem .

Kenny, do you have a part number for the compressor to city water hose? I checked Home Depot's website and cannot find that. Thanks.

I'm sorry but I don't.
I bought it 10 years ago to winterize a small motel with only about 10 rooms.

Here's several different ones from Amazon.

Thanks. I should have looked on Amazon, but wasn't sure what to call them. I have the small plastic adapter, but have been concerned that the air hose pulling downward might break the fitting on the camper. This seems like a better arrangement.

There a lot of different brands including Camco that connect directly to an air compressor for 5-8 dollars.

I’m getting one of those!
I’ve been using a little blower attachment with a bunch of hockey tape wrapped around it...

I bet, given the low PSI, you could buy a barbed hose repair piece and a small section of air hose and some hose clamps or crimp rings and make your own.

All you need to do is drain the the heater.

For years all I did was drain the water system and then blow out the lines with a compressor . Then we had a particularly cold winter and the toilet valve froze and the water pump . Now I blow out all I can and the add some pink stuff to the intake of the water pump untill it reaches the toilet . Then unscrew the spray heads for toilet and sink , and put some in all the traps . Nothing in water heater or water tank . No problems since .
