Need to break vacum in water softener drain line
have a 1/2" pex drain line running outside as I can't run it into my septic system anymore.......I installed a Watts N36 vacuum breaker at the highest point to allow all the water to drain and eliminate any freezing problems. During regeneration the valve disk flutters making a moaning/groaning sound. Any ideas? Drain is under house pressure when it runs....
Possible answer from another forum
A response to another similar question about drains freezing from water held by a vacuum lock stated that if the end of the drain line is open then the water should drain back to the highest point in the drain line which is in my floor joists.......so my vacuum breaker was actually a waste of money.............does this make sense??
