Installation / Maintenance

adjusting the Flow

The drain pump can pump up to 27 gallons per minute (GPM). Normal
sink drains allow only 5 to 6 GPM to flow. Adjust the discharge shut-off/
flow balancing valve as follows so that the pump does not cycle on and
off when the faucets are on full.
1. Run water into the sink. The pump will start when it detects water.
2. Check for leaks. If leaks are found, unplug the pump power cord
and fix the leaks before proceeding.
3. Put a stopper in the drain and allow the sink to fill up a few inches.
4. Open the discharge shut-off valve, open the faucets, and remove
the stopper to drain the sink.
5. The pump will start. Adjust the discharge shut-off/flow balancing
valve 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 the 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
w hen the washing machine discharges into it, unless the sink is ONLY
used for washing machine discharge.
nOtICE:
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.

This pump requires very little maintenance and should provide a long
service life. Problems are rare; when the pump flow drops off, the most
likely cause is something solid going down the drain and jamming the
impeller.
To clear a jammed impeller:
1. Unplug the Pump.
2. Close the discharge shutoff valve.
3. Bail out the sink as much as possible.
4. Disconnect the union, unscrew the pump from the sink tail piece,
lower the pump to the floor, and slide it out from under the sink (see
Figure 3).
5. Remove the six housing screws (see Figure 4).
6. Clean out the pump. Make sure that the pump discharge is clear. If
necessary, replace the impeller.
7. Install the new gasket (included with impeller). Reassemble the
pump.
8. Raise the pump back into position, thread it back onto the sink tail
piece, and reconnect the union.
9. Plug in the pump. Run water in the sink until the pump has run
at least one complete cycle to make sure the pump is operating
correctly and there are no leaks.
