2A. Install the discharge plumbing and check
valve, using pipe thread sealant tape - NOT
pipe joint compound.
2B. Tighten the pipe into the pump (hand tight+
1-1 /2 turns).
2C. Install a check valve in the vertical pipe to
prevent flow backwards through the pump
when it shuts off. To prevent airlocking the
pump, drill a 1/8" (3.2 mm) hole in the
discharge pipe just above where it screws into
the pump discharge. Install the check valve
above this hole, but keep it as close to the
pump as possible. Be sure the hole is below the
waterline and below the check valve.

3. Place the pump in the sump; make sure that
nothing interferes with switch operation. For
tethered switch models, the tether length
should be 3-1/2" (See Figure 3).

CAUTION
I
Risk of flooding.
Can cause
personal injury and/or property damage. Make
sure the pump cannot move in the sump. If the pump
moves when it runs, the piping or sump wall may
interfere with the switch and prevent the pump from
starting or stopping.
