Water Treatment
Code of practice for treatment of water in domestic hot
water and central heating systems
BS 7593: 1992
Poor system design leading to ingress of air
Flush system in accordance with BS 7593: 1992
Add an inhibitor such as Sentinal X100 to the System
Make sure Softened water is not used in heating system
