Components with Valve Extension Kit:
User Supplied Pipe
The components-only kits
require user-supplied Riser
and Handle extension pipes.
Pipes must be measured, cut,
assembled and installed by
the user. Square-cut ends
must be maintained .

Note 1: Riser and Handle Pipe are not the same length. Sch 40 and/or Sch 80 pipe as
well as ABS may be used. Special cement must be used to join PVC to ABS.
Note 2: When 6" SDR35 pipe is used, adapter fits pipe inside diameter.
Note 3: DO NOT use Sch 80 for 3" Riser pipe.

plug in place, carefully measure
from plug top to where the extended
access plug top will be located
(Length D). Note: This dimension
is the basis for determination of the
actual riser pipe length.
From Table 3, use
STEP 2
dimension "D" to calculate Riser
and Handle Pipe lengths.
Cut Riser and Handle pipes to caculated length. Square-

STEP 1
sure to prevent solvent cement contact with the
internal body or fl ap assembly, as this could
prevent proper operation and sealing. Repeat
connection on opposite end.

STEP 3
Handle Extension Pipe.
(Length D)
If Pre-Made Extension is taller than required, Riser Pipe &
Handle Extension Pipe may be trimmed as follows:
STEP 1
extension temporarily fi tted to pipes, fi nd & pencil mark new (lower)
access plug top height onto riser pipe
or coupling.
STEP 2
the reference point to the plug top.
This dimension equals the amount
of material (Z) that must be trimmed
from Riser Pipe and the Handle
Extension Pipe.
