Lavatory Cisterns

Lavatory Cisterns

Lavatory cisterns are an essential component of a modern toilet system. They are designed to hold and release water to flush the waste from the toilet bowl. These cisterns come in various shapes, sizes, and materials, but they all work on the same principle. The cistern is usually placed above the toilet bowl and connected to it through a pipe. When the user presses the flush button, the cistern releases water into the bowl, which then flushes the waste away. The first lavatory cisterns were made of ceramic or metal and were manually operated. They required the user to pull a lever or chain to release the water. However, modern cisterns are mostly made of plastic and are connected to the toilet bowl through a flush valve. These valves are controlled by a button or lever, which triggers the release of water from the cistern. Lavatory cisterns are available in two main types: gravity-fed and pressure-assisted. Gravity-fed cisterns rely on the force of gravity to release water into the toilet bowl. They are the most common type of cistern and are relatively inexpensive. Pressure-assisted cisterns, on the other hand, use compressed air to force water into the bowl. They are more expensive but are more efficient and powerful than gravity-fed cisterns. In conclusion, lavatory cisterns are an essential part of modern toilet systems. They come in various shapes, sizes, and materials and are available in two main types: gravity-fed and pressure-assisted. These cisterns are designed to hold and release water to flush the waste from the toilet bowl, making them an essential component of any modern bathroom.
