Fire and explosion hazard. PVC glue is
highly flammable. Do not use near fire or flame, and
follow glue manufacturer's instructions carefully.

nipples.
11. Glue both nipples into the 90° elbow.
12. Attach the check valve (Exploded View, Key No. 1) to
the close nipple that does not have the union

13. Assemble the union. Make sure that the elbow/check
valve alignment with existing plumbing is correct.
14. Install a 2" or 3" vent pipe (check your local plumbing
code) in the 3" NPT threaded vent port on the pump
chamber. You can use a 3" threaded pipe or glue the
vent pipe to a male adapter (3" vent pipe) or 2" slip x
3" NPT reducer bushing (2" vent pipe), and then
thread the assembly into the vent port on the pump
chamber.
15. Connect the discharge pipe and vent pipe into the
atmosphere (or through the existing house vent pipe) ac-
cording to national and local plumbing codes. An auto-
matic or mechanical vent device will not work with this
system. The toilet will not flush unless properly vented.
