Using air to blow out water lines for winterizing?
For the past three years I have used low pressure, about 20psi, to blow all the water out of the water lines in my 5th. wheel then pump pink RV antifreeze into the system (after bypassing the water heater).
I just purchased a new Sabre and the dealer rep., told me using air pressure was not recommended due to all the check valves in the system.
I can understand if high pressure, 60 or 70 psi, was used but not very low pressure as has been recommended by a lot of people.
Any comments on using air during winterizing?
