Non-Metallic Rigid Conduit, Fittings and Accessories
Installation
Lay conduit in the trench as straight as
possible. Avoid undulations up and down
and side to side.
Incorrect Method
Correct Method
Stretch duct in one direction
away from secured end
Spot backfill
Keep bends as gradual as possible
Secure end
Trenching
Trenching
Trench should be graded true and free from stones or soft spots.
Backfill should also be free of stones and be firmly tamped around
the sides of the conduit to develop maximum supporting strength.
Tamping on top of the conduit is not recommended.
Backfill
In rocky soil where it is impossible to have an even trench bottom,
a selected backfill should be put in before laying the conduit.
Selected backfill (not tamped) at least 6" over the top of the conduit
is recommended. After final backfill is placed, tamping may be used
to finish the grade.
Duct Placement
Duct may be unreeled directly into trench or along side trench
and subsequently placed in trench. After placing in trench, secure
one end and stretch it by hand to take up the slack. Spot backfill
to hold in position. Do not use mechanical stretching equipment.

Changes in Direction
Avoid unnecessary turns, dips or changes in direction. Keep
bends as gradual as possible to ensure ease of cable pull-in
after duct installation.
Pneumatic Rodding
All commonly used vacuum or pressure rodding equipment can be
used to rod P&C Flex
™
. The line carrier (mouse, puck, rocket) should
be soft, flexible material designed to fit snugly into duct without
interference.
Mechanical Rodding
All commonly used mechanical rodding equipment can be used
to rod P&C Flex
™
. The tip should have a ball-type arrangement
to keep rod from catching in the convolutions on the inside of duct.
