EXTENDABLE BACKWATER VALVE
MAINTENANCE GUIDE
Pre-Installation
• Slide Upper Collar through
Outer Riser Pipe. If collar does
not slide freely through pipe,
check to see if pipe is
"out-of-round". If so, replace
Outer Riser Pipe.
• Backwater valves require
adequate drop between the
flood rim of the lowest fixture
and burial depth of the valve in
order to function properly.
We recommend a minimum
slope of 1/4" per foot or as
recommended by the UPC
and IPC codes.
• Additional PVC bushings are
enclosed for use if needed.
Discard if not used.

Outer Riser Installation
1 At proper depth, install the Clean Check Valve Body
between the building and the sewer lateral, with the "FLOW"
arrow of the Valve Body pointing downstream away
from the building.
2
Rotate the Valve Body until the opening is facing directly
upward. A level may be used across the top of the Valve Body
to verify horizontal positioning.
3
Cut the Outer Riser Pipe to the required length. Cement
and insert while keeping the inside of the body clean of debris.
CAUTION:
Be certain that excess solvent cement has not
impeded proper seating of the Flapper Assembly or the proper
seating of the flapper sealing surface of the Valve Body.
Inner Riser Installation
4
Cut the Inner Riser Pipe to a length (3-1/2") shorter than
the Outer Riser Pipe.
5
Cement the Flapper Assembly to one end of the Inner
Riser Pipe.
6
Cement the Upper Collar to the other end of the Inner Riser
Pipe, while aligning the center of the Finger Hole with the center
of the Flapper on the opposite end.
7
When cement is dry, loosen the thumb screw in the Upper Collar
and slide the Inner Riser Assembly – Flapper Assembly first –
into the Outer Riser Assembly with the flat sealing side of the
Flapper facing the inlet side of the Valve Body. Lower the Inner
Riser Assembly into the seating area of the Valve Body, making
certain that the Thumb Screw is inside the inside wall of
the Outer Riser Pipe and NOT on
the resting on the top edge. Seat
the Flapper Assembly by rotating
as necessary until it locks in place.
Visually inspect that the Flapper
Assembly is installed correctly.
8
IMPORTANT:
Prior to installation
of the Threaded Adaptor & Plug
(with the Inner Riser Assembly
properly installed) cut a reference
notch into the Outer Riser Pipe.
This saw cut notch should be
aligned with the molded Notch in
the Upper Collar. For future removal,
alignment of the notches will
quickly indicate that the flapper is
seated correctly.
9
IMPORTANT:
Tighten the ¼" Stainless Steel Thumb Screw
until it seats snugly against the Inner Riser Pipe, fixing the Inner
Riser Assembly in place.
10
Cement the Threaded Adapter to the Outer Riser Pipe
riser and screw the Threaded Plug into the
Threaded Adapter to complete installation.
