2 years.
• It is good operating practice to replace old batteries with new ones at the start of the
irrigation season.
• In-line valve recommended operating water pressure range: 10-80 PSI.

prOBLEM:
In-line valve does not close despite solenoid activation
CAUSE: Outlet flow may be too low
SOLUtIOn: Increased flow rate by adding drip emitters or micro sprinklers
CAUSE: the solenoid orifice or adapter inlet if used is blocked
SOLUtIOn: Flush and clear port
prOBLEM:
In-line valve does not fully close
CAUSE: Debris stuck in diaphragm
SOLUtIOn: Remove bonnet and diaphragm and clean diaphragm
prOBLEM:
