Boiler Losing Pressure

Boiler losing pressure is quite a common boiler problem and indicates various issues that may be happening to your boiler. Most boilers have a pressure gauge built into it that makes it easy to tell if it’s losing pressure.

Constant and continuous water pressure is essential to make sure your boiler is working efficiently. There could be several possible causes to a boiler losing pressure. A leak somewhere in your boiler system may be dripping the cold water out causing low pressure. Also, if you recently did the bleeding of your radiators, its possible that pressure was lost then.

However, you wouldn’t know that your boiler is losing pressure until you check the pressure gauge. For example, a water leak may be small and unnoticeable. The pressure gauge is usually located in front of the boiler. It is usually set around the 1 bar, and the position it was set during installation is usually indicated by a red needle.

If your boiler dropped pressure several times, regularly check the gauge. Repeated lost pressure is an indication that your boiler is experiencing problems.

You can try to trace what’s causing your boiler losing pressure. Check all visible joints, including the water radiator valves and connections, for water leaks or water stains. If you don’t see any leaks, check under floor pipework as well. Next, check the water pressure relief valve for any overflow or water discharge.

Most modern combi boilers maintain pressure through the flow of cold water from the mains supply using a mechanism known as the ‘filling loop’. Some boiler models may allow you to manually regulate this water flow/ This means you can also re- pressurise your boiler. Your boiler manual will have instructions on how you can do this yourself. Be careful if you decide to re- pressurise the boiler by yourself.

There may also be instructions on the rear of the control panel. If your boiler panel needs tools to remove it, don’t touch it. Hire a qualified engineer to do the job.
