D4 Services 
Completely unblock your heating system. The Power Flush service removes black sludge and gas trapped in radiators, clears blocked valves and pipes and frees up blocked pumps, allowing
your system to work more efficiently and effectively.
Why do we need Power Flushing? Debris and silt can build up over time causing your heating system to work inefficiently, and in some cases, can cause the boiler to break down, meaning an expensive repair or replacement bill.
Prevent this from happening and ensure that your heating system is noise free, and efficiently heating your house or workplace.
How does it work? The purpose built Power Flushing pump is connected to the heating system and forces water through the system at a very
high speed, but at low pressure so that no appliances are damaged in the process.
Once the system is cleared, it is filled with clean cold water, and normal running operation returns in just a few minutes
D4 recommend Power Flushing before installing a new boiler for a clean running and efficient heating system.
