Sorry....but this is yet another question about loss of pressure in system.
I had my central heating boiler replaced in May with a worcester bosch boiler and currently having to top up the pressure twice per day.
I top up to 2 bar and within about 8 hours it is back to 0.
This drop from 2bat to 0 equates to approx 2.5 litres, so if I am topping up twice a day, thats 5 litres of water going somewhere.
The installer (Chris) has been back 3 or 4 times and cannot find anything leaking above ground. This is a bungalow so have checked loft, all rad valves and been down on our hands and knees over all carpets to try to find a damp patch. Also, no sign of any damp on walls.
The rooms all have carpet or laminate floor on top of a concrete floor. The pipework is in the concrete floor itself, and not in a channel infilled with a sandy cement.
We have tried Fenox leak sealer, but that has been in for over a week and has made no noticeable difference.
I have ready hundreds of posts regarding loss of pressure and most of them end up with the leak being found pretty easily.
The old heating system was not pressurised, so this could have been leaking for a long time as the header tank would have refilled it without us knowing.
So, the reason for this post is..........has anybody got any ideas of what else we can try?
Can we hire a device to detect this size of leak without lifting carpets and digging up floors?
any suggestions would be gratefully received.
Thanks, ian
