Treatment of Water Circulating Systems
•All recirculatory water systems will be subject to corrosion unless an appropriate water treatment is applied. This means that the efficiency of the system will deteriorate as corrosion sludge accumulates within the system, risking damage to pump and valves, boiler noise and circulation problems.
•When fitting new systems flux will be evident within the system, which can lead to damage of system components.
•All systems must be thoroughly drained and flushed out. Using for example
•System additives - corrosion inhibitors and flushing agents/descalers should be suitable for aluminium and comply to BS7593 requirements, e.g.
Failure to flush and add inhibitor to the system will invalidate the appliance warranty.
•It is important to check the inhibitor concentration after installation, system modification and at every service in accordance with the manufacturer’s instructions. (Test kits are available from inhibitor stockists.)
