PUMP CHAMBER INSTALLATION GUIDELINES
(United Kingdom Health & Safety at Work Act 1974)
DO NOT BEGIN INSTALLATION OF THIS CHAMBER UNTIL YOU HAVE READ AND
FULLY UNDERSTOOD THE REQUIREMENTS BELOW.
THE CONCRETE BACKFILL SHOULD BE DESIGNED TO PROTECT THE CHAMBER FROM ALL
EXTERNAL GROUND AND GROUND WATER PRESSURE. THEREFORE IT SHOULD BE
WATERTIGHT.
ANY GROUNDWATER ALLOWED TO LEAK BETWEEN THE CONCRETE BACKFILL AND THE
PUMP CHAMBER IS LIKELY TO CAUSE A BUILD UP OF PRESSURE WHICH WILL DAMAGE THE
CHAMBER.
WE CANNOT ACCEPT RESPONSIBILITY FOR DAMAGE OR DEFORMATION OF THE CHAMBER
OR PIPEWORK CAUSED BY EXTERNAL GROUND, GROUNDWATER PRESSURE OR GROUND
MOVEMENT DURING OR AFTER INSTALLATION.
DO NOT COMMENCE WITH INSTALLATION IF YOU CANNOT CONTROL ANY GROUNDWATER
PRESENT IN ORDER TO PROVIDE A DRY EXCAVATION.
IF NECESSARY LINE THE ENTIRE EXCAVATION WITH A CONTINUOUS LAYER OF PLASTIC
SHEETING PRIOR TO INSTALLATION.
As with all site work the dangers of working with water and electricity pose severe threats to health
if obvious and fundamental precautions are not taken. Therefore if you are in any doubt to any of the
following, please do not hesitate to contact us.
All site work should be undertaken by qualified personnel only.
Lifting & Storage
Tank delivery is direct to site, you will need to offload the tank. This should be carried out by either the
main contractor or by a specialist sub-contractor.
Great care should be taken when lifting and handling the chamber and suitable equipment should be
used at all times.
The nature of the design means the centre of gravity of the chamber is likely to be offset.
The chambers are best lifted by crane using webbing lifting straps. Any 'lifting eyes'
provided on the chamber are untested and should not be used as the sole lifting point for the chamber.
Any storage site should be free of any object which may cause damage to the chamber, and the
chamber should be secured to prevent any rolling.
WE CANNOT ACCEPT RESPONSIBILITY FOR ONSITE DAMAGE
