Long shot but thought i will ask anyway. Any plumbers in the house? Got some weird knocking/banging noise (not sure how to describe it best) from heating pipes i think. It usually comes after boiler has stopped for about 10 minutes or so. I have bled all the radiators but noise is still there. Before i rip off the floorboard and hopefully will not have to rip off the tiles in bathroom (knowing my luck i will have to) does anyone have any idea what to look for? Word of warning i am useless when it comes to these things and i have done all that i feel comfortable to do(bleeding the radiators) I am ok to fix lose pipes if i discover any when i rip the floorboards up but that is where my capabilities end i am afraid. Anybody have an idea or should i just admit defeat any pay the man to sort it for me?
