Installation
Mount the pump
NOTE: DO NOT use plumber's pipe threading compound ("pipe dope") on plastic pipe; it can damage the plastic, causing leaks and
piping failure and void the warranty.
1. Place the sink in its final location.
2. Remove any existing drain fittings back to the tail piece. Make sure the existing tail piece does not leak.
NOTE: If the sink-drain tail piece is not 1-1/2 in. NPT, you will have to adapt it (bushings, reducers, etc.). In this case, wrap all joints with
PTFE pipe thread sealant tape before making connections.
3. Glue the 1-1/2 in. PVC pipe into the female adapter (purchase separately).
WARNING: Fire and explosion hazard. Be sure to follow the cement manufacturer's instructions when using PVC cement. Do not use
near fire or open flame.
4. Wrap the threads of the tail piece with 1 to 1-1/2 turns of PTFE pipe thread sealant tape. Thread the 1-1/2 in. NPT female adapter onto
the sink-drain tail piece. Thread it hand tight plus 1/2 turn with a pipe wrench or slip joint pliers. DO NOT overtighten.
NOTE: The vertical height from the check valve to the pipe outlet should be at least 6.5ft to void check valve leakage.
5. Wrap the threads of the 1-1/2 in. male adapter with 1 to 1-1/2 turns of PTFE pipe thread sealant tape and install it in the pump inlet.
Tighten it hand tight plus 1/2 turn with a pipe wrench or slip joint pliers. DO NOT overtighten!
6. Measure the 1-1/2 in. PVC pipe against the drain and the pump and trim the pipe to fit.
* Required and included
