The Clean Check
®
Extendable Backwater
Valve is designed for easy re-installation.
To properly re-seat the valve, slowly lower
the inner assembly back into the outer
riser pipe and rotate it until you feel the
unit drop into place. The notch in the
upper collar should now be lined up with
the notch in the outer riser pipe.
Important:
Correct alignment of the
notch in the upper collar and the notch
in the outer riser pipe is necessary for
correct repositioning of the inner assembly.
After seating the inner riser assembly
properly, hand tighten the thumbscrew
until it re-seats against the inside wall of
the outer riser pipe. Be certain the thumb-
screw is NOT resting on the top of the
larger outer riser pipe. The flat side of
the flapper should be resting, in the
closed position, on the building side
of the valve body.
Replace the threaded cover plug.
Using the finger hole provided above
the thumbscrew of the upper collar,
extract the inner riser assembly.
Clean any debris
from the flapper, inner
riser assembly, and the
in ground valve body.
Inspect the flapper
for any deterioration
or damage caused by
the harsh environment
in which it operates. If
deterioration is present,
replace the flapper
(they are available from
your local plumbing
contractor or wholesale
supply house.)

The following steps will guide your plumber
through a proper inspection of your Clean

Extendable Backwater Valve.
Locate the Clean Check

cover. It has been
placed outside your building, between the
sewer lateral cleanout and the building.
Remove the threaded cover plug by
unscrewing it to expose the upper collar of
the inner riser assembly.
Loosen, but do not remove, the stainless steel
thumbscrew located inside the upper collar.
Note the locations of the thumbscrew and
opposing notch. There are two notches:
one in the outer riser pipe
and one in the upper collar.
This will be necessary for
correct repositioning
of the inner riser
pipe during
re-installation.
