
The Chezy PP Inspection Chamber is light weight and more
economical than the traditional brick chamber, their
functional performance is excellent.

Load factors on chambers vary according to type of soil,
compaction during installation and groundwater. An
important function of the chamber is to resist these
factors and to maintain the hole in the ground.

(PP Inspection
Locate position of chamber, dig hole to a depth of 300mm (1 foot) below
the main sewer pipe connection. Backfill and level the bottom of the hole
by tamping (compacting) the earth to 50mm below the socket of the
outgoing pipe. For ground with High Water Table, anchor base of chamber
to a concrete slab of width 600mm X 600mm and thickness of 100mm.
Connect the base of the inspection chamber to the pipe leading to the
main sewer line, if there is no existing pipe, connection can be done in
the future. Rotate body to the best suitable position and push it into
base. Use liquid level gauge to ensure the inspection chamber is level.
Locate the position of where all the pipes going to the Inspection Chamber will
enter the ground level. Dig trenches sufficiently wide and depth of the trench
should be sufficient to allow the pipes to pass below the ground beam. Rotate the
Body of the Chamber such that the maximum numbers of sockets are able to be
fixed to the incoming trenches. Trenches that are not in line with the sockets of
the Inspection Chamber can be joined to the Chamber by the use of 45° bends.
Push the incoming pipes to the socket of the chamber and WORK
BACKWARDS FROM THE CHAMBER TO THE POINT OF ENTRY OF THE
PIPES OUT OF THE GROUND. Use 45° bends or Chezy Flexible bend where
required. Clean inside of chamber and make sure it is clear of all foreign
objects and debris. Cover the chamber with Chezy's temporary cover
Place earth/concrete on the temporary cover holding an indicator pipe on
top. Backfill the trenches and hole where the chamber is located tamping
every 100mm of backfill being filled. Tamp to 100mm above the pipes and
backfill to ground level where only the indicator pipes are visible to be
able to locate the chamber in the future.
At the end of the project, locate the indicator and excavate the soil until the chamber is
reached. Remove the temporary cover and replace riser/riser with socket to the
required height. Put the collar and cover of the chamber and adjust to the required
level. Once again use liquid level gauge to make sure chamber is level. Backfill the hole,
tamping until 50mm below the collar. Concrete surround the collar to a minimum depth
and width of 50mm. Secure the cover with screws on collar to prevent removal. The job
is completed.
STEP 1
Unscrew the stainless steel screw (4 nos) on
the cover
STEP 2
Remove the cover of inspection chamber.
STEP 3
Observe for any debris/foreign objects that
might cause blockage.
STEP 4
Flexible
Rod
Using a standard normal flexible rodding rod,
insert the head of the rod into any pipe outlet
that is suspected to cause blockages.
STEP 5
Service the pipe using the rod until it clear
from any hindrance/blockages.
STEP 6
Using a small scoop or the rodding rod itself to
remove the foreign object out from the
inspection chamber.
STEP 7
Replace the cover and tighten the stainless
steel screw tightly.
