Powerflush Ts & Cs

Power flushing terms and conditions

1. These terms & conditions are in addition to our standard terms & conditions and should be read in conjunction with our standard terms & conditions.


2. When requesting or confirming a booking to have a powerflush carried out, you are confirming that you have read understand and agree to be bound by these and our standard terms & conditions.


3. A Powerflush is a method of restoring heating performance to an old heating system, by connecting a high performance reservoir pump into the heating circuit and pumping a number of chemicals at high velocity around the system to break down any limescale & sludge deposits (Magnetite). Then pumping the deposits out of the system to a drain, until the system water runs relatively clear. Then a chemical inhibitor is added to the system to help prevent the build-up of sludge deposits in the future.


4. Although a “powerflush” is the best way to restore and cleanse a system we cannot guarantee to completely clear all deposits from all systems and on very rare occasions the improvement in a systems performance is limited. This can usually be rectified by a second flushing of the system which we can carry out at a discounted rate. On even more rare occasions, blockages can be so severe in certain sections of pipe work, that these sections of pipe work may need cutting out and replacing, if this is necessary an extra charge will be made to the customer.


5. All work carried out that incorporates a powerflush will be carried out in a professional manner following industry standard methods. Corrosion and Scale cause internal damage to the central heating system and boiler. Depending on how advanced this damage is, leaks may occur during or after the powerflush. The power flushing doesn’t cause the leaks but it can uncover leaks that have been sealed up by the sludge or lime scale inside the system which is removed during the power flushing process. Unfortunately there is no way of telling if leaks are going to occur. 


6. “Dunlop P H & G Ltd” cannot be held responsible for any leaks that occur or for any damage caused to decorations, furnishings (including carpets), fittings, existing pipe work, cylinders or tanks, caused while carrying out the powerflush. Therefore any leaks or damage caused by leaks, are not covered under our guarantee. (However this may be covered under your house insurance). Whilst the chance of a leak occurring during power flushing is rare, leaks generally occur while we are on site so we can deal with them straight away.


7. In the unlikely event that during the power flushing process any leaks should occur, repairs will be carried out at our standard labour rates.
