So having all this free time in the days of social isolation, last Friday I drained all the rv antifreeze out of my lines and flushed them good and got the camper ready for the summer...if we get a camping season. Put water in the fresh tank and ran it into the lines and we even had a meal in the camper last weekend. Anyway, now I see a few days coming up with overnight temps in the 20's and daytime temps in the 30's. Thinking of just draining all the lines and blowing them out with air and emptying the fresh water tank. Or, would just leaving the lines pressurized with the pump on be safe? Suggestions?

It would help to know what temperature the RV is designed for. If all the water parts are enclosed you could probably just turn the heat on inside and keep everything from freezing. Otherwise draining and blowing everything out would be safer. Craig

I’m for the safe way. Blow them out.

Are the water lines all inside the camper and accessible by cabinet doors, etc.? That is the design of my HR. On cold nights I turn up the furnace, leave the lower cabinet doors open and run a little electric heater into the water pump/water tank compartment. We have camped comfortably and used the water system in temps well below 20 deg.

It's no different than camping late in the fall. I'd drain the fresh water tank, or turn tank heaters on if you have them. Then turn the furnace on about 50 for the overnight.

Did you sanitize the lines after draining the pink stuff?

I'm facing the same temps so I drained the tank and hot water heater and just blew out the lines. Easy to do and takes 5 mins.

Cheapest is just to re-winterize with a couple gallons of antifreeze. On ours, we can do it in about 15 minutes.

Since that appears to be your normal process, just follow the normal process. Yeah, in theory, you could open the drains, blow it out or keep the heat on...but probably better to stick to the process you know works.

Looking at your rig in your signature I would imagine it has decent cold camping capabilities and would just drain all tanks including WH, set furnace to keep interior temps comfortable. Our rig has a fully exposed underbelly and would still just drain all fluids from rig under scenario you stated. That is us, of course do what you deem necessary to have peace of mind.

That is the design of my HR.This is the same on my Forester,fresh water tank and ALL water lines (except low point drains) are above the floor, as someone else said, set the furnace, or electric heater to 50 and forget it.
