How to check if boiler is leaking?
If your boiler is leaking, you should check the pressure gauge to see if the pressure is too high. If this is the case, it’s likely that the pressure relief valve is trying to release some of the water in the system to bring the pressure back down to a comfortable level, which can lead to your boiler dripping water. The valve needle should be between 1 and 1.5 bar (usually shown on the gauge as a green zone). If the needle is higher than this, or in the red zone, you may need to bleed the radiators to release extra water.
