attached to overflow warning pipe (supplied loose).

PIPEWORK 

 

Fig. 1.4 Typical Pipework arrangement 
 
1.3.4.1 

Ensure the isolation valve & strainer (supplied loose) is fitted to the mains water inlet. Particles/debris 
must not enter the mains water solenoid valve, otherwise it may stick open and cause 
leakage/flooding. 

1.3.4.2 

Mains water pressure should be 1Bar minimum, 3Bar maximum. If the pressure exceeds 3Bar then a 
pressure reducing valve (not supplied) must be fitted before the mains water inlet to the pumpset. 

1.3.4.3 

Ensure the quick release filter (supplied as loose item) is installed in the breaktank overflow warning 
pipe and connected to drain with an air‐break e.g. tundish in a conspicuous location. 

1.3.4.4 

Under no circumstances fit an extra non‐return valve

, to the discharge, as it may interfere with the 

correct operation of the non‐return valve already fitted as standard in the pumpset. 

1.3.4.5 

Connect site pipework to mains water inlet and discharge, ensuring adequate support is provided to 
avoid imposing pipe strain on pumpset. The connecting pipework should not be smaller than that of 
the pumpset i.e. 15mm mains water inlet, 22mm discharge 

1.3.4.6

 

Where Hydraulic Accumulator(s)/Expansion Vessel(s) are supplied as a loose item, they must be 
installed/connected correctly before operating the equipment, otherwise serious damage from over‐
pressure/pump overheating could occur. 

1.3.4.7

 

All hydraulic accumulators and expansion vessels fitted to the system must have isolating and drain off 
valves to enable them to be serviced and removable pipework to enable the diaphragm to be 
replaced.
