    Just had a new concealed toilet cistern installed. Is it necessary to put the lid on the cistern tank as my plumber has fitted the tank too high, so with the plastic lid on the cistern the lid on the cabinet lid doesn't fit without forcing. So he said the lid on the cistern isn't necessary?.

    The whole point of a concealed cistern is that conceals all the cistern and associated pipework.

    I would get the plumber back to rectify.

    The lid prevents evaporation causing damp in the void.

  4. hi john
    the lid should always be fitted, as per jimbo reply,
    it always good working practise to fit the lid so is setting out your work,
    so get your plumber back i would say it is sub standard,
    manufactures supply the lid for a good reason
    good luck

    If you are embarrassed to tell the plumber he is at fault, then ring the cistern manufacturer or supplier and get them to confirm the lid must be fitted. Then use their wording to your plumber.

    I have a concealed cistern with no lid. It has not been a problem in 10 years
