Powerflush Terms & Conditions


All Powerflushing work carried out will be subject to our standard terms & conditions.


These terms & conditions are in addition to our standard terms & conditions and should be read in conjunction with our standard terms & conditions which are available on request.


A chemical 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.


Although a Powerflush is the best way to restore and clean a system we cannot guarantee to completely clear all deposits from all systems and on certain 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.


The payment is to be settled in full as per our standard terms in any given circumstances. The customer can not hold the payment if the results from powerflushing is not good.


Corrosion and Scale cause internal damage to the central heating system and depending on how advanced this is, leaks may occur during or after the Powerflushing procedure. The powerflushing 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 although it is only likely on very old systems.


“Gas safe service ltd” cannot be held responsible for any damage to decorations or furnishings including carpets, or leaks from fittings, existing pipework, 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 Powerflushing is rare leaks generally occur while we are on site so we can deal with them straight away.


The customer is responsible for any leak or damage occur due to use of products/services  which becomes faulty,any presence of fault or a  product which is not to current standard products. The customer is responsible for any damage occured while working on dead fittings.


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