There should be no problem with the Drain Master working in those temperatures as long as the liquid in the pipes is not frozen. I have this on my RV and have used the valves in below feezing temps with no issues. Remember to angle the valve up to allow any water that possibly seeps into the valve to drain. If your only able to have a slight angle this could possibly be an issue in freezing temps if that water were to freeze in there before it got out.
