    Hi, I have a vented central heating system with large water tank & smaller F&E tank in the attic.

    The water level in the F&E tank rises until it dribbles out of the overflow pipe into the garden.

    I have read the FAQ section & am working through the list.

    I have changed the ballcock & replaced it with a fluidmaster one yesterday, but today, the water level has risen again overnight. The vent pipe does not seem to be dripping. I left a jug under it and not much water collected.

    I turned off the stopcock to both the F&E tank/water tank & ran a bath & the level in the F&E tank actually rose slightly above the overflow pipe!

    Does this indicate a cylinder coil leaking? Hot water cylinder was replaced about 5 years ago.

    Or blocked pipework? a check with a magnet is mentioned. WHat is this?

    ANy help gratefully received.

    Dave

    You normally find the higher tank will fill with water

    And the lower one will leak water out the over flow. If the coil has a hole in it.
