- Old decrepit failing underground solenoid wiring replace with new sheathed quality multi-core wire with node boxes fitted and operation well for 4 months. The LEDs in the control nodes make system diagnostics much easier. | - Old decrepit failing underground solenoid wiring replace with new sheathed quality multi-core wire with node boxes fitted and operation well for 4 months.
