Submersible Pump Installation
Refer to “WSP Submersible Pump Installation Diagram” on page 11 for the following
instructions. Be certain the sump basin is clean and all power to the pump is shut off. If the
pump fails to operate properly after installation, refer to “Troubleshooting Checklist” on
page 14 or contact a Honda servicing dealer.
General Materials Needed
• One can of PVC cement (read the instructions carefully)
• One can of thread compound (read the instructions carefully)
• One male PVC adapter (1-1/4" for 1/3 HP, 1-1/2" for 1/2 and 3/4 horsepower models)
• Enough rigid PVC pipe and couplings to reach from the bottom of the sump basin to
the discharge (1-1/4" for 1/3 HP, 1-1/2" for 1/2 and 3/4 horsepower models)
• One Check Valve.
Tools Needed For All Pump Installations
Pipe wrench, Slot screwdriver, 24-tooth hacksaw, knife or round file.
Step 1. Apply thread sealant and thread a male PVC adaptor into the pump discharge
opening.
Step 2. Cement a 15" piece of PVC pipe to the adaptor. Use appropriate diameter piping.
Drill a 1/8" relief hole in the pipe 5" above the pump connection. This hole
prevents the pump from air-locking.
Step 3. Clamp the Check Valve to the top of the 15" PVC pipe with the water flow arrow
pointing away from pump.
Step 4. Lower the pump into the basin. Clamp needed PVC discharge pipe and fittings to
the open end of the Check Valve.
