Step 8 · Reconnect Electrical Wiring

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Open the cover of the pressure switch. Referencing the photos you took earlier, reconnect the electrical wires to the correct terminals. Typically, there are two terminals for the power from the breaker and two for the wires going to the pump. Ensure the copper wire is securely under the screw heads and tighten them firmly. A loose connection can overheat and fail. Replace the pressure switch cover.
