Wayne Sump Pump ESP15 Installation

Lift the main sump pump's float switch and drain the pump's basin, the container in which the main pump sits. By lifting the float switch, the floating bulb, which connects to the pump's housing, turns on the pump motor. Once the pump has cleared the water from the basin, lower the float switch. Pull the main sump pump's electrical plug from its wall receptacle to disconnect its power source.

Measure the distance from the top of the main sump pump's housing to the bottom of the basin with a tape measure. Add 1 inch to the measurement and transfer the total to the main sump pump's discharge pipe, measuring from the bottom of the basin up the discharge pipe. Place a pencil mark at the appropriate spot on the discharge pipe. Make a second pencil mark on the discharge pipe 2 inches up from the first pencil mark.

Slip a PVC cutter's blade over the discharge pipe and position the blade on the bottom pencil mark. Squeeze the PVC cutter's handles together until the blade cuts through the pipe. Repeat this process on the upper pencil mark. Discard the 2-inch-long discharge pipe cutout.

Clean a 1/2-inch-wide strip around the outside of both cut ends of the discharge pipe with PVC primer. The primer cleans the residue off the outside of the discharge pipe. Coat the cleaned ends of the discharge pipe with PVC glue.

Slip the glue-covered ends of the discharge pipe into the ESP15's Tee-fitting's vertical ports with the arrow on the Tee-fitting pointed up. The discharge pipe connected to the main sump pump slides into the Tee-fitting's bottom vertical port, and the other discharge pipe connects to the Tee-fitting's remaining vertical port, the port that the arrow points at. Twist the Tee-fitting until its horizontal port faces the main sump pump.

Push the ESP15's flapper valve into the Tee-fitting's horizontal port and keep the tab on the flapper valve face-up. The tab slides into the notch on the top of the Tee-fitting's horizontal port. Slip the ESP15's hose clamp over the flapper valve and rest the clamp against the Tee-fitting.

Force the ESP15's discharge port, the round port located at the bottom of the pump, into the exposed end of the flapper valve. Continue to work the pump toward the T-fitting until the pump housing touches the flapper valve.

Twist the ESP15 until its alignment mark, located on the pump housing near the discharge port, aligns with the flapper valve's tab. This should leave the ESP15 resting at a 30-degree angle to the main sump pump's discharge pipe. Then position the hose clamp over the flapper valve's tap. Tighten the hose clamp's screw with a slotted screwdriver turned clockwise.

Hold the ESP15's float switch against the discharge pipe's Tee-fitting with the float switch's wire face-up. Strap the float switch's wire to the discharge pipe with the ESP15's two wire ties. Position the lower wire tie about 2 inches above the float switch and the upper wire tie about 2 inches above the lower wire tie.

Align the holes on the back of the ESP15's control box with the four screws on the battery container. Hold the control box against the container and tighten the screws with a Phillips head screwdriver turned clockwise. Then set a 12-volt, deep-cycle battery into the ESP15's battery container.

Slip the control box's red battery connector onto the battery's positive terminal. Tighten down the terminal's thumbscrew. Place the control box's black battery connector over the battery's negative terminal and tighten down the terminal's thumbscrew.

Slip the ESP15's float switch wire connector onto the control box's wire terminal labeled "Float Switch," the terminal located on the left. Push the ESP15's pump wire connector onto the control box's wire terminal labeled "Pump," the terminal located in the middle. Then slide the ESP15's battery charger wire connector onto the control box's wire terminal labeled "Charger," the terminal located on the right.

Plug the ESP15's battery charger and the main sump pump's electrical plug into the wall receptacle.
