INSTALLATION INSTRUCTIONS

flow. This check valve is mandatory when sharing a discharge line with

another pump (i.e. a back-up pump or a second primary pump).

(a)

When a check valve is used, a 1/8 in. air bleed hole must be drilled in

the PVC pipe above the pump. Drill the hole at a 45° angle toward

the bottom of the sump to avoid splashing water outside the sump

pit. Make sure the hole is above the water line and below the check

valve. If a hole is not drilled above the pump, an air lock may prevent

the pump from operating.

7. Install a gate valve or ball valve if required by any codes.

8. The horizontal discharge pipe must be positioned in a downward

slope so any remaining water will drain away. Failure to do this will prevent

water from exiting the pit and damage the pump if the line freezes.

9. If you are replacing an old sump pump:

(a) Unplug the pump from the outlet.

(b) Loosen the check valve or rubber union by unscrewing the bottom hose

clamp. (If the existing system is installed without a check valve or rubber

union, saw the pipe apart above the sump pit.)

(d) If the adapter fits into the new pump, screw the pipe into the pump. If

not, cut a piece of rigid PVC pipe and connect it to the new adapter by

cleaning and cementing the two pieces together. (Follow the instructions

on the PVC cleaner and cement.)

(e) Loosen the enclosed hose clamp by turning the screw counterclockwise

and slip it over the pipe on top of the pump.

(f) Hold the float switch against the discharge pipe so the cage is below the

bracket.

(g) Position the bottom of the float at the height you want the pump to

activate and turn the screw clockwise to tighten the hose clamp, but do

not tighten it completely at this time.

(h) Lower the pump into the sump by the handle.

(i) To avoid debris pouring into the float, it should be positioned on the side

of the discharge pipe opposite the drain tile. Note: It is desirable to

mount the float below the drain tile that empties into the pit. Mounting it

above the drain tile would allow water to fill the drain tile before the pump

is activated. (See diagram on page 4).

(j) Once the switch is in the desired position, tighten the hose clamp.

(k) Connect the pipe on the pump to the existing discharge pipe with a

rubber union or check valve and tighten the hose clamps securely.
