Problem blowing out sprinkler
Is there a way you can blow it out after the breaker? I also have a
vacuum breaker and I had a similiar problem. Sometimes if I lowered the
air output a little , the breaker would close, then I would gradually
increase the PSI output again.
What I eventually did is put a drain valve after the breaker, with a
seperate shut-off as to not backfeed into the breaker.
