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.
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.
