Hi,
I have heard knocking from the front of the house pipes/radiators? for about a year now. I can hear it when sat in the living room and also the bedroom above it. All night, every two minutes a knock knock knock - three times always on the dot. Especially when its cold or the radiators have been on and cooling. I understand the metal contracts but this sound different to that tapping.
I have bled them for the first time in years but nothing came out but lots of water straight away. Is there anything else I can do or what is causing this as it wakes me up numerous times every night. Thanks.
