Power Flushing Your System: A Step By Step Guide

Sometimes flushing out a central heating system is unavoidable, even though the procedure will be done by a skilled professional, it can be helpful to know how it is done.

 

Diagnosis

 

Unless there are clear signs that your central heating system is in need of a power flush, testing the system first is good practice. Along with general operation checks and questions, water samples should be taken, visually inspected and then tested with apparatus to diagnose the systems condition. Not all systems can be power flushed due to their design, some can be flushed but the effectiveness of the process may be limited, in such instances other recommendations may be made. If you choose a reputable service like Power Flush Cheltenham, there will be no need to worry about hidden fees and unnecessary examinations. FORTHRIGHT will only recommend a power flush if it is needed.

 

The Procedure;

 

Power flushing utilizes a machine that uses low pressure, high volume water in combination with chemicals to break down and mobilise sediment. Usually warm water is used during process as this will often speed up chemical reactions and make the process quicker. The machine should be connected in a manor that allows for maximum flow around the system and that will allow it to be effective on the complete system, usually this involves attaching the machine where the pump is situated.

 

During the process the engineer will adjust the flow of water to varying parts of the system so sediment can be mobilized and extracted effectively.  Engineers will flush a whole system several times, even changing the direction of the water through the circuit to maximize the effect. This process is repeated until  sediment has either been fully dissolved or mobilised in the water, any contaminated water is then purged until it resembles drinking water.

 

Once completed, the engineer should check the system water with test equipment to ensure that the dissolved solids in the system water closely resemble that of drinking water, the system water PH is acceptable, no visual signs of particulates are present and there is flow to all parts of the system. Once all checks are satisfactory the system will then be treated with inhibitors to slow corrosion, scale formation and other such things as microbial growth.

 

Finally the system should be balanced and it's operation fully tested. Often significant improvements in performance  are noticed immediately. For more information visit our website:- https://www.forthrightservices.co.uk/
