I have the above-mentioned boiler with three radiators connected. The boiler has recently started making a whistling noise every so often when it pumps hot water to the radiators. I can feel the right-hand pipe leading from the base of the boiler and it is this pipe making the noise.
Any idea how i can stop it?! It used to work perfectly! I did play around with the lockshield valve a few weeks ago, which may have coincided with when the noise started, but have since tried returning it to where it was before and the noise remains.
Thanks for any help.
