Buying guide

Sizing irrigation control wire

Run one wire per zone valve plus one shared common, so a controller needs at least one more conductor than it has stations. Pull a couple of spares for future zones. All of these are direct-burial rated.

Cable Conductors Valves it runs Best for
18-221 valve (1 hot plus 1 common)A single remote valve or a pump-start relay
18-55Up to 4 valvesA small 3 to 4 zone system
18-77Up to 6 valvesA typical 6-station residential run
18-99Up to 8 valves7 to 8 zones, or 6 zones plus spares

18 AWG handles most residential runs; step up to 14 AWG on long pulls where voltage drop can keep a solenoid from opening. Wire back to the controller and land each leg on a zone valve, sealing every splice with a waterproof connector.

How to Choose Irrigation Wire & Connectors

Irrigation control wire carries the low-voltage signal from your controller to each zone valve. Use multi-strand UF (direct-burial) wire with one strand per valve plus a common, and add a spare strand or two so you can expand or swap a bad conductor later.

Make every underground splice with waterproof, gel-filled connectors rated for direct burial. Dry wire nuts corrode and fail. Size the wire gauge to the run length so full voltage reaches the solenoid.
