blowout fails
I have a 6 zone residential system that cycles though nicely when water is present. When I turn off the water and connect the compressor for blowout it allows the air to flood all the zones at once making it impossible to blow out system. I have sucessfully blown out this system for several years.????
Thanks for any guidance
