This article is in effect an addendum to the post Repairing A Toilet Silent Fill Valve which explains how to access and dismantle such a valve and inspect or change the diaphragm that sits in the valve.

The article endeavours to explain to the reader how the complete valve works so that they understand the order in which physical processes take place and why they follow on from each other as they do. The theory behind the workings of the valve are developed from the basic principles of forces and pressures acting on the individual parts but without the detail of too many mathematical formulae.

Traditional porcelain cisterns flushed with a handle have their lids held down by gravity.
Some Dual Flush toilet cisterns, like my Armitage Shanks1 Ascania have their lids held in place by the Geberit Flush Button Mechanism2. The Button Socket, mounted in the cistern lid, is held down by a plastic screw attached to an internal part within the cistern.
This article gives advice on this type of dual flush toilet cistern lid removal.
