Now we know the relative levels of the tanks I know that the cylinder coil is not leaking!
The second bit is only whats expected as you cold comes direct from the mains.
We still dont really know about the ball valve level.
Can you view the big tank when no water has been used for say 30 minutes and see the level of water in it compared with the overflow pipe level? It should be about 50 mm below!
