To apply these connections, apply PTFE tank to the male threads of the Tank Connector and Male
Iron. Screw the 1¼” Coupling Female TH/TH (6) onto the Tank Connector, following the same process
for the Male Iron into the Coupling.
Connection to be made with 36mm OD Solvent Weld Waste Pipe into the Male Iron would be as per
point g) and h) as above.
2. Select a suitable location for the pumping station. It is extremely important to site the system with permanent
access in mind for routine maintenance of the system.
3. Prepare the chamber for all connection, incoming pipe/s (inlet/s and cable duct). To do this you must select the
location and drill the appropriate sized inlet/s and cable duct for the connections (see Section 7 Accessories’
for inlet and cable duct rubber seals).
4. A reinforced waterproof concrete sump must be formed for the chamber to be installed within. This will
ensure that any pressure present is not transferred onto the chamber itself. Furthermore, when constructing
the reinforced waterproof concrete sump it is important that adequate space is made for connections to the
chamber e.g. inlet/s, cable ducts and discharge. Consideration must also be made regarding the depth and
orientation of all connections to ensure that they line up with the chamber.
It is imperative that you consult with a structural and waterproofing engineer when designing the reinforced
waterproof concrete sump ensuring that it allows for the anticipated pressures and that they are not transferred
onto the chamber.
5. In all instances, the chamber MUST be positioned on a flat, level, concrete base of dimensions sufficient to
fully support the base of the chamber. Once the reinforced waterproof concrete sump has been formed, lay
a 100mm mass concrete within your reinforced waterproof concrete sump, carefully position the chamber
onto the WET concrete base ensuring that no loose debris is inadvertently knocked onto the base, under the
chamber during this procedure. Push the chamber into the wet concrete ensuring that the concrete is fully
imbedded into the bottom of the chamber. Position it such that the inlet/s, cable duct and discharge pipe work
are correctly aligned.
6. Once the chamber is positioned, connect all pipes (inlet/s, cable duct and discharge) to the chamber.
7. Whilst the concrete base is still WET backfill the chamber with a mass concrete. The concrete must be evenly
poured around the chamber ensuring that no voids are left within the concrete. Care must be taken to ensure
that any pipes (or other connections) made, are not damaged. During the concrete pour, ensure that the
chamber is vertical (by use of a spirit level across the chamber’s opening). The chamber MUST be ballasted
with water at the same rate as backfilling such that the level difference between the water and the backfill does
not exceed 150mm at any time.
Please ensure that when pouring the concrete backfill, suitable steps are taken to prevent the concrete entering
the chamber and any connected pipework.
8. The system is supplied with an access cover, this is loose and should sit directly above the top of the chamber
access shaft. Please note that the chamber is only suitable for installation to a maximum of 300mm deeper than
supplied from finished floor level.
