How toilet cisterns (tanks) work
Cisterns are either lever or push button operated. Cisterns operated by a push button are available in single (6L) or dual flush (3L/6L) depending on the range. The majority of cisterns are now internal overflow; this means in the event of a failure, the water will be contained within the unit. A flushing trough is an apparatus which serves several WC pans from one long cistern body. It is designed in this way to allow more frequent flushing. These can be found in schools, colleges, and public toilets, although they are becoming less common.
• How they are made
Pottery is made by a blend of clays, fillers, and fluxes being fused together during the firing process. A white or coloured glaze is applied and is fused chemically and physically to the clay body during the same firing process. The finished product (vitreous china) has a very hard surface and is resistant to fading, staining, burning, scratching, and acid attack. Due to the firing process and natural clays used, it is normal for the product to vary in size and shape, and +/- 5 mm is normal.
