Installation / Maintenance

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 when 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 clean-
ing. To avoid this, install a lint trap or bag type filter in the
washing machine discharge line and clean it out regularly.
MAINTENANCE
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 two unions, lower the pump to
the floor, and slide it out from under the sink (see
Figure 3).
5. Remove the four housing screws (see Figure 4).
6. Clean out the pump (see Figure 5). Make sure that the
pump discharge is clear.
7. Make sure that the O-Ring is properly seated and
reassemble the pump.

8. Raise the pump back into position and reconnect the
unions.
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.
