Hi my boiler was fitted 2 years ago roughly and been working fine until 4 months ago it started making a high pitched noise over time it has got progressively worse to the point im worried it might blow up. The noise is like vibrations in the watee pipes if u touch the copper pipe below the boiler uou can feel the vibration but up stairs in the bathroom and bedroom it is much worse what could this be, the pressure is perfect. Please any help much appreciated. Lynn

Does this happen when you use any hot water outlet ? If so it's the inlet cartridge
Im going to record the noise in the morning as it's worse around 6 am hopefully someone might be able to shed some light onto what is going on. Thank you lynn
hello sorry for delay in getting back to you, it happens at all different times in the night in the day when no one is using the water or heating can be off it even happens if i turn the boiler off at the dial on the boiler. Any ideas please
