Converting Sprinkler Zone to Drip Irrigation and Adding a New Drip Zone

Converting Existing Spray Zone to Drip

At the existing valve, install a pressure regulator (typically 20–30 PSI) and a filter (150+ mesh) to prevent clogging and blow-offs. Use adapters to connect 1/4" distribution tubing to the former sprinkler risers. Cap unused outlets.

Adding a New Drip Zone

1. Locate existing valve manifold.
2. Cut a tee into the mainline (pressure supply line).
3. Install a new automatic valve on the tee.
4. Run new wire from this valve to the controller (if automatic system).
5. Program the new zone on the controller.

Key Considerations

• Drip runs longer but uses less water — adjust schedule accordingly.
• Pressure regulation is critical; high pressure blows off drip emitters.
• Filter prevents sediment from clogging tiny drip passages.
