PIPING
1. Cut and dry-fit the pipe and fittings as required
for 1-in (DN25) diameter discharge pipe (may
be reduced to 3/4-in [DN20] diameter if local
code allows it).
2. While dry-fitting the discharge pipe, position
and mark the location of the pump unit
discharge fitting.
3. Cut and dry-fit 1-1/2-in (DN40) vent pipe as
required to ensure that the vent pipe does not
interfere with other components. Make the
connection to the pump unit with the provided
street elbow. A 2-in x 1-in 90º discharge fitting
has been provided.
4. Temporarily set the toilet in place to check that
there is no piping interference. Remove the
toilet and set it aside.
5. Clean, prime and solvent weld the discharge
piping and pump unit discharge fitting.

Proper venting is required
When applying solvent weld
two side inlets. These inlets can be attached
using the 2-in MPT (outside diameter) or the
1-1/2-in (DN40) slip (inside diameter). These
inlets must have the inner portion drilled out using
a 1-3/4-in (44mm) hole saw. This is to ensure
there is no leakage problems from inlets not in
use. When utilizing side inlets, install a check
valve on the incoming line.
