    Hi All,

    My toilet is leaking when its flushed - there are drips at this point here.


    I thought it must be related to where the flush valve meets the cistern / basin. However the flush valve can be removed from the cistern so I removed it and turned the water back on so it was constantly flowing from the cistern down to the toilet and it didn't leak?. I put the flush valve back, let it fill up and flushed and it started leaking again! Any ideas?

    I was going to take the cistern off but the nuts are jammed tight so hoping WD40 will do its magic.

    Thanks

    Do nut washer needs replacing between cistern outlet and pan inlet.

    A full tank flush creates more pressure so causes leak. When you take the cistern off you will find the the large round doughnut shaped washer that seals between the two.
