How can I tell if my backflow preventer is leaking from the weep hole?

You can tell it’s leaking if water drips or sprays from the weep/relief hole when no fixtures or irrigation zones are running. A steady discharge usually means the internal check or relief valve isn’t sealing and needs service. Short bursts after shutoff can be normal pressure relief. This is common on irrigation backflow assemblies in Austin and Bastrop.

Quick checks:

• Turn off downstream use; if it still leaks, call a plumber.
• Close the downstream shutoff; if leaking stops, debris may be in the check.
• If flow is heavy, shut water off.
