Low point valve question

[Deano112]

Hey Everyone,

This is our first camper with low point drains. Our dealer winterized our camper but I noticed the low point drains were still closed. Should these remain open over the winter. What are these drains actually for? Are these to be closed during the camping season?


Thanks

Did the dealer put antifreeze in your pipes? If so, the valves are closed to keep the antifreeze from running out.

The valves are there so you can drain the water out to winterize.

The valves are closed during normal use.

If your dealer winterized using RV antifreeze they remain closed. If only blown out with air, I would leave them open. They are to remain closed when using trailer, otherwise your water will drain out when using the onboard pump, and will flow water all the time when connected to city water. If you have a manual, I strongly suggest having a read on the water system.

Yes the put antifreeze in the system. I will make sure they’re closed.

If you blow with air leave the valve open. Valves can't freeze up in the open position. There is a school of thought that says a valve will not leak later on if left closed. The thinking is the valve sealing faces can not corrode when closed. I leave mine open until I de-winterize. I have had no Leaks.

I leave them all open, the only 'valve' closed is the toilet.

By leaving them open, won’t some of the antifreeze drain out. I don’t believe they blew the lines out.
