OPERATION
Plug in the Pump
AFTER the pump is completely installed, plug the switch into a GFCI protected, properly grounded outlet. Plug the pump
into the back of the switch's plug.
Adjusting the Flow
The drain pump can pump up to 21 gallons per minute (GPM). Normal sink drains allow only 5 to 6 GPM to flow. Adjust
the discharge ball valve (C) as follows so that the pump does not cycle on and off.
Run water into the sink. The pump will start when it detects water.
Check for leaks. If leaks are found, unplug the pump power cord and fix the leaks before proceeding.
Put a stopper in the drain and allow the sink to fill up a few inches.
With the ball valve in closed position, open the discharge ball valve (C), open the faucets, and remove the stopper
to drain the sink.
As the pump starts, adjust the ball valve slightly beneath the half-way position. Adjust the discharge ball valve (C)
until the pump runs continuously while the faucets are running and the sink is draining. If the water level rises with
the pump on, slightly open the discharge valve to balance the flow. If it drops, slightly close the discharge valve.
Washing Machine Use
Washing machines usually discharge more water than faucets do, and it is normal for the water level to rise in the sink
while the pump is discharging. Do not adjust the discharge valve to match the flow when the washing machine
discharges into it, unless the sink is ONLY used for washing machine discharge.

† For easier removal for servicing or cleaning,
install a 1-1/2" solvent union in the drop pipe.
Figure 3: Pump Removal
NOTE: Washing machine discharge water
contains fiber and lint. Unfiltered washing machine
discharge could plug the pump and require pump
disassembly for cleaning. To avoid this, install a
lint trap or bag type filter in the washing machine
discharge line and clean it out regularly.
