Installation 3
1A.Minimum sump size: 10" (254mm) diameter by
10" (254mm) depth for vertical switch models;
14" (356mm) diameter by 18" (457mm) depth for
tethered switch models.
1B.Construct the sump pit of tile, concrete, steel, or
plastic; it must meet code requirements.
1C.No clay, earth, sand, or gravel in the sump (they
will clog the pump). Keep the pump inlet screen
clear.
2A.Install the discharge plumbing and check valve,
using teflon 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.
2D.To reduce noise and vibration, cut the discharge
pipe near the pump and fasten a short length of
rubber hose (1-7/8" (48 mm) I.D., e.g. radiator
hose) into it with hose clamps.
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).
4. Finish installing the necessary plumbing. Follow
the glue manufacturer’s instructions for safety
precautions and curing time.
Risk of flooding. Make sure the pump can-
not 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.
