DIY steps
- Shut off the main water supply to the sprinkler system and drain the water from the valve by opening the drain valve or removing the drain cap. Wear protective gloves and safety glasses to prevent injury from sharp edges or flying debris.
- Dig around the sprinkler valve to access the solenoid and valve body. Use a shovel to carefully remove dirt and debris, taking care not to damage the valve or surrounding pipes.
- Disconnect the wires from the solenoid and remove any retaining clips or nuts holding the solenoid in place. Use an adjustable wrench to loosen any corroded or stuck parts.
- Remove the old solenoid and valve diaphragm, taking care not to damage the valve body or surrounding pipes. Inspect the valve body for mineral buildup or corrosion and clean as needed.
- Install only the solenoid and diaphragm specified for the valve model, ensuring proper alignment and securement. Reconnect wires with listed waterproof direct-burial connectors inside the valve box, then replace retaining clips or nuts.
- Turn on the main water supply and check the valve for leaks or proper function. Run a test cycle to ensure the sprinkler system is working correctly.
- Backfill the excavated area and compact the soil to prevent settling or erosion.
