 Sprinkler leaking after turnoff
Author: plumbjay (CA)

After years of working fine, one sprinkler in a line started leaking after the anti siphon valve was shut off. I installed backflow preventers, but now the anti siphon valve leaks after turnoff. Is the ant siphon valve bad? Or should I allow the sprinkler to leak?

If an rpz was installed there should be no need for an additional back flow preventer

RPZ only protects the PUBLIC'S water.

A local anti-siphon protecting the USER'S water would be HIGHLY recommended (even if not code required) as the irrigation would be DOWNSTREAM of the RPZ.

If, however, a dual-check assbly was installed on the irrigation line the anti sipohon is no longer required.
