I have ALWAYS used air. Just make sure to set your air compressor to no more than 50 psi. If you hook up air at 120 psi you'll break something.

Now in the pee traps, for sure use some RV antifreeze. I'll keep a little in the toilet bowls to keep the rubber seals from drying out.

I use RV antifreeze and I throw 3 of my cholesterol pills in with the antifreeze to keep the water lines open.

Wouldn’t an injectable like ProLiant be easier?
