i) Place a Socket Union (3) over the plain end of the Tank Connector (do not use solvent glue at this
stage).
j) Measure and cut a length of horizontal Pipe required between the placed Socket Union (3) and Tee
Piece (8). Tee Piece to be positioned above secondary pump Male Threaded Adaptor, taking into your
measurement the length of pipe inserted into the fittings (do not use solvent glue at this stage).
k) Measure and cut a length of link pipe for the Tee Piece (8) and 1no. Elbow (2) connection to the Bilge
Pump, taking into your measurement the length of pipe inserted into the fittings (do not use solvent
glue at this stage).
l) Measure and cut a length of link pipe for the Elbow (2) and Socket Union (3) connection for the
Secondary Pump, noting that these fittings should be placed directly together (do not use solvent
glue at this stage).
m) Measure and cut a length of vertical pipe for the Socket Union (3) and Male Threaded Adaptor (1)
connection for the Secondary Pump, taking into your measurement the length of pipe inserted into
the fittings (do not use solvent glue at this stage).
n) Place a Socket Union (3) onto the exposed PL/TH Barrel Nipple (9) coming from the 1¼” Brass Non-
Valve (V) (do not use solvent glue at this stage).
o) Measure and cut a length of vertical pipe for the Elbow (2) and Socket Union (3) connection for the
Bilge Pump, taking into your measurement the length of pipe inserted into the fittings (do not use
solvent glue at this stage).
p) Chamfer, clean and dry the connection edges of the PVC lengths, using an appropriate PVC Solvent
Cleaning Fluid, making sure these areas on the pipe and within the fitting are free from any debris/
dirt.
q) Check all the pipework is in place correctly before applying plenty of PVC Solvent Cement on
required connections, wiping away any excess that may become visible with a clean cloth.
r) For connection of the external discharge pipework, you will be left with 2no. 1¼” PVC male thread
on the outside of the chamber. We recommend that you use 1¼” Class E PVC Pressure Pipe, but
should the installer wish to use 36mm OD Solvent Weld Waste Pipe (white), 2no. PVC 1¼” Coupling
Female TH/TH (6) and 2no. 32mm Male Iron (7) is supplied within the fittings kit.
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).
