Hi all,
Apologies for the lack of knowledge here, but I will try and progress with what the internet has taught me so far.
We bought our first house exactly a year ago, and all has been fine with the boiler and hot water system though the initial survey advised that the boiler was 20 years old and in need of replacing in the next couple of years. We have a gravity fed system.
Over the last couple of weeks (as the cold weather has started to come in to the UK), we have started getting sporadic loud vibrating noises after showers (we have a power shower which itself is very loud).
As it's a semi-detached and the vibrating news reverberate throughout the whole house (and we assume next door), this is something I've tried to investigate each time, but the noise can stop after 5-10 minutes.
I have managed to find that next to our large cold water tank in the loft, there is a smaller tank which I believe is a feed and expansion tank. Within it there is a cistern with a float valve, and although the tank has plenty of water in it, if I open the float valve manually, the vibration and sound quickly stops. There doesn't appear to be an issue with the float valve - it works fine, but there is always a lot of water in it which keeps the valve closed.
I believe the supply pipe that feeds the float valve is mains water (but that is only from what I've read online - it's hard to follow the pipes), so I'm not sure where that vibration is coming from apart from pressure within the pipes. I guess the other option is that it's pressure from the boiler and that is something I'll check when I get home.
Has any body experienced this or similar before, or have any advice?
Thanks in advance,
Matt
