Hello - hope you can help me. I have a Potterton Suprima 50 boiler that has recently developed a strange whistling noise.
The noise starts about 10 minutes after the boiler fires up and then continues for about 15 minutes when it goes quite. If the boiler is on for a while, it may happen again a couple of hours later.
My local plumber has been twice and basically given up so any advice would be appreciated.
Thanks in advance.
