All you need to do is drain the the heater.

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..

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 .

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.
