Is water treatment required when plastic pipework is being used?
A. Water treatment is required for plastic pipework although the actual processes may be different if there is no mild steel present in the circuit. Newly installed plastic systems contain particulate matter, which needs to be removed before bringing the system on line. There is a potential for microbiological problems if adequate water treatment is not undertaken. It is very rare to find an entirely plastic system and the selected water treatment for the system needs to be suitable for all the plant, pipework and fittings present.
