Watermaster 57114 Won't Shut Off: Stuck Valve Emergency Fix

Sprinklers Flooding Street? Shut Off Water at the Backflow Preventer

If your Watermaster 57114 timer runs continuously and only the house main stops it, you have a mechanically stuck valve—not a controller issue.

Immediate Steps

1. Locate the backflow preventer (usually near water meter or irrigation tie-in). 2. Turn both ball valve handles 90° to isolate irrigation system. 3. House water remains on.

Why This Happens

• Debris in valve preventing diaphragm seal.
• Solenoid plunger stuck open.
• Excessive pressure (>80 PSI) causing valve weeping.

Next Steps

With water off, manually cycle each valve (turn solenoid ½ turn CCW then back) to free stuck plungers. If flooding recurs, call an irrigation pro to disassemble, clean, or replace the faulty valve.

Controller Note

Replacing the Watermaster timer battery won't fix a stuck valve. The controller only sends 24 VAC signals—it cannot force a valve closed mechanically.
