All homeowners and even those renting should be aware of the signs of deteriorating pipes, bursting or splitting pipes in your pipework which may lead to, at the very least a nuisance, and in more extreme cases a household disaster incurring massive cost in damages to your building or possessions.

A central heating leak could also lead to long term damage to your heating system as it’s rust inhibitor will be diluted each time you are required to top up the pressure. Rust particles in the system can damage the boiler and rusted radiators and pipes will eventually need replacing.

Is your central heating boiler losing pressure?

A central heating system should maintain pressure, however, pressure within the central heating system will increase and decrease as the central heating system heats up and cools down again. If the boiler pressure drops regularly and needs to be topped up with new water, this is a tale tale sign of a problem within the central heating system.
