Heating System Clean
After an installation or modification of a central-heating system, the system and associated pipework should always be flushed through with water to get rid of any foreign objects and flux that can be left behind during the process. This debris if left in the system can cause corrosion or damage to the valves and more importantly the pump. Professional tradesmen like a Chingford Plumber will carry out this work as standard.As a protective measure and to also give the systems pump some protection whilst the cleaning routine is carried out, the best thing to do is to remove it. In place of the pump you can place a short piece of hose held with two jubilee clips. This completes the circuit again for cleaning. Of course at any time if you do not feel confident, call a professional plumbing company like Chingford Plumbers for a reliable service.Using a strong cleaner may show up minor leaks sealed by corrosion so a mild cleanser is the best option which should be fed into the system through the feed-and expansion tank or a radiator through its bleed valve. A good regime is to run the cleanser through the system for a week, with the boiler set to a fairly high temperature. When complete, turn off and drain the system. Refill and drain it several times, using a hose to run mains-pressure water through the system while draining it. Should the boiler be making loud banging noises, treat it and its immediate pipe work with quite a powerful descaler. Run this on the hot water program only. There are some agents that must be neutralized before you can add a corrosion inhibitor.Once complete, and the pump is replaced, you can turn the pump impeller using a screwdriver before the system is run. Do this to make sure it’s clear and free to rotate. If feel some resistance, isolate and remove the pump again, and clean and refit the impeller if required.
