4. Install a check valve in the vertical pipe (see
Figure 2) 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.

Risk of flooding. Can cause

If a flexible discharge hose is used, make
