Hi
Grateful for any advice.
Had a new central heating system installed (valiant ecotec 630, indirect 'megaflo' (joule brand), wet under floor heating in the kitchen (about 30-35m2) and 11 radiators about a year ago. All installed and gas Safe certified a year ago
Had some issues with it for about 6 months. There has been a pressure loss of about 0.6bar over 2 weeks. This has varied in speed.
The ceiling under the megaflo (in the lort) had visibly dripped water twice. Once our builder (as it was during the build) went up there and tightened a pressure release valve. All was well until about 6 months ago where the same thing happened British gas reset the valve but said ok. Since then the system has lost 0.6bar every 2 weeks.
The ceiling under there remains damp looking and last week a very small area of paint peeled suggesting it's still leaking but I can't obviously see anything when going up there.
There is no obvious leak elsewhere. I have tightened all the rad valves (no air in the rads and crystal clear water). There was a drip on the manifold for the underfloor heating but we had this tightened up (slowed it but pressure loss the same).
Our builder (who I don't think we will be calling back) did lord knows what when we weren't around- he put our magna clean behind a cupboard wall and denied we ever had one so it's unaccessible so we will have to cut an access hole now. I'm not sure of there may be a source of leaks.
We managed to eventually get the installers details (one for the CH system and one for the tank) who didn't think the pressure loss could be from the ceiling (as said that was likely a surge in the mains water pressure). They said keep an eye on it and if continued may be an underfloor leak and to try leak sealer.
Not really sure who to call on this? Leak detection companies said the leak is too small to find and call plumber. Installer said the same, British gas didn't want to touch anything?
Any help greatly appreciated.
