LOL, like it :lol:
No water meter. I am wondering if the network of pipes are picking up background noise and the two radiators in question just happen to be in the right place in the system to 'vent' the noise. Like putting a sea shell to your ear.
Hi, sounds like a distant hissing and the odd 'plop'.
I have a hot water cylinder in the airing cupboard. I can't hear the water pump running and am wondering why I can hear water moving. Thought I may have a leak but nothing is apparent.
Hi, if I put my ear to two of my upstairs radiators (bath room and spare room), when the heating is off, I can hear what sounds like running/moving water. I can't find a leak though. Any one have any ideas as to what might be ging on? Thanks.
