two tanks in loft small one and larger one, the leaking one is the smaller, so far plumber has replaced 2 ball valve and 2 speed couplings and new ball valve and float in header tank, also drained the heating circuit, added sludge remover flushed and tested and supplied new 15-50 pump, tested and inhibitor added. total bill so far is over £500. we know he has done work on both tanks but drip is still apparent and no improvement. the ball cock in small tank seems low in tank and not on top of water. he does not know how to stop the ballcock from sinking and is now suggesting a new boiler. i am a pensioner can anyone out there help me.
thank you for your time.
