Hi all,
Hope you can help.
We've just had the mains feed up the drive replaced, and a water meter fitted. Usage seemed rather high to us.
So, we turned off the cold water feed to the tank in the loft and the meter stopped moving - we assumed it was leaky ballcock on that basis (it was dribbling). Happy about that, straightforward fix...
However, we just had a few days away and turned the water off entirely.
On switching it back on, it was quite clear that the tank was only half full (or so).
So we're assuming therefore that there's a leak elsewhere.
But...
Tank overflow is not dripping and tank itself is not leaking.
Only one cold tap (in the bathroom) is fed from the tank - and is off. Showers, toilets and cold taps elsewhere are mains fed (and aren't leaking anyway).
Central heating feed and expansion tank - nothing seems to be going on there.
That kind of says to me that there's a leak on the hot water system somewhere?
There's no wetness under the immersion or the boiler (or on the walls+ceilings).
Are we missing something? Is there anything else that could be causing the cold water tank to be continually filling (albeit at a dribble?) Is there anything else to try?
Hope you can advise. Not looking forward to the prospect of pulling up floors... Anyone any experience of a problem like this? How was it resolved?
Thanks in advance.
Cheers, all.
