A small connector pack for valve wiring

The Rain Bird WPCONN10 pack includes ten waterproof grease cap wire connectors for compatible irrigation wiring work. They belong with low-voltage sprinkler valve service, solenoid changes, and controller station checks.

The pack is small enough to keep in a valve-station pouch beside tags, a marker, spare solenoids, and a route notebook.

Protected splices need careful prep

Wire connectors work well when the wire ends are clean, matched to the connector, and placed where they can be checked later. Keep the valve box tidy before opening a splice area.

Use the connector with the irrigation wire size and controller setup called for by the system. When the work involves unclear wiring, a licensed irrigation or electrical professional can keep the repair safe and traceable.

Label the station while the box is open

A wire repair is a good time to write down the controller station, wire color, valve name, and nearby head zone. Put the note on a waterproof tag or in a garden record page before closing the lid.

That small record helps future checks stay calm because the wiring and watering route are linked in plain language.

Good match

Choose this ten-pack for compatible sprinkler valve wiring service where waterproof grease cap connectors belong in the repair kit.

What to know
