Javi, where we live sounds similar to your area; the temps only go below freezing a handful of times during the winter, and we use our trailer year round, so I almost never fully winterize, but I'm thinking to be on the safe side for those handful of extra cold nights, I'd like to do something similar to your routine. I bought a fitting for blowing out the lines; what air pressure is high enough to be effective, but still safe for the plumbing?

30-35 psi is plenty

Be sure to run the water pump dry before blowing out the lines. And flush the toilet, & outdoor faucets as well as the bath, & sink faucets with the air pressure on. Also blow out the black tank flush line..

Thanks. You are absolutely correct. Just one check valve, at the top. Can't wait for spring to get to work on it.
Thanks for all the feed back.

good tips, thanks! I would have totally forgotten about the blank tank flush!
