| This allows for the hard flushing of a central heating system with minimal dismantling. Flushing the system loosens corrosion deposits and sludge which is then removed from the system leaving pipes and radiators clear and free for good circulation. |

| The following are some symptoms to watch out for which may indicate your central heating system may have a sludge problem: |
|
| Sludge is a residue resulting from the reaction between the water in your system and the steel in the radiators. It can build up over a period of time and cause circulation and flow problems. |
|

- Radiators need frequent bleeding
- Repeated pump failures/corrosion deposits in pump casing
- Strange and unpleasant noises from the boiler
