Winterizing My FW

[Batsman53]

It is necessary to completely winterizing your unit if you maintain a little heat inside the using portable heaters? Our unit is park in our backyard and connected to 30AMP service off my shed. I thought about just draining it and using air pressure to blowing the lines. So my question is would it be necessary to add RV anti-freeze too?

I blow out all the lines with air as well. Works great, the only thing you need the anti-freeze for are p-traps in all the sinks.

Edit - just reread your post and saw that you're gonna blow out the lines. In that case, like already posted, the traps should suffice. Just a reminder, don't forget to blow out the black tank flush and empty any outside spigot lines (I only mention it 'cause I nearly forgot them last year).

Don't forget to add antifreeze to the toilet bowl
