I have a dual flush cistern operated by a lever at the side. It is supposed to give a short flush, (half the cistern) if the level is depressed and let go. For a full flush (whole cistern) you press and hold the lever. I know the toilet was installed in the early 1980's.
I had a plumber come and look at it and he said it was working OK. He tested it by flushing a single piece of toilet paper. He also suggested that the force of the flush would be reduced by a build up of deposits under the rim over the years.
Does the plumber know what he is talking about or is it just an old cistern he doesn't understand or know how to repair.
Is it possible for it to repaired and return to a full flush which is needed sometimes.
I do know the difference between a half and full flush but the plumber left me feeling as it I didn't know what I was talking about but I can remember the cistern emptying on a full flush and now it only ever half empties even when the lever is pushed and held.
