winterizing question Low point drains open or closed

Blow the lines out, leave the low points open.

Probably no bugs if you winterize when temps are low.

But for myself not going to use RV till spring when bugs might be out and about. Or what about someone that has to store their RV for longer length of time. Personally after asking question...I thought that mold near any openings would play a roll more so than bugs. But every place is different. With me mice getting inside my RV biggest worry. Dang they can fit into the smallest places and make a mess.

I close mine.

I just totally drain then use pink anti freeze pumped through anywhere water would go.Then I drain the pink and leave drains open,It greatly reduces taste in spring which for me is always 8 months from winterizing time.Boo Hoo.

Leave drains open. The first year I winterized (blew out the lines) on my trailer and then closed the valves I had two cracked valves the following spring.

Op here...Correct, no anti-freeze in lines, just little down each drain. So no water to freeze in lines. Was really thinking about bugs or anything that might harm system

Thanks

What if you taped a Baggie around the line end? Would catch any drops of water well away from the drain - but would keep out wasps/mud daubers, etc that are looking for a place to live out the winter?

That's a winner, I'm on it.

After you drain you should use compressed air to clear low spots in pipes. Make sure the water heater is empty. remove plug on Atwood or anode on Suburban tanks.
Close you low point drains, Put plug/anode back in water heater.
Pour antifreeze into toilet, sink and shower drains.
