The toilet cistern is known as the toilet tank, a vital component of the toilet system that holds water used for flushing. Though tucked away behind the toilet lid, this toilet part contains several essential parts that work together for a smooth and efficient flush every time. You need to understand these components to diagnose common issues and maintain their toilets better.
The Flush Valve and Flapper
Every toilet cistern contains a flush valve, which controls the release of water from the tank into the toilet bowl during flushing. Attached to it is the flapper, a flexible rubber or plastic seal that keeps water inside the tank until you press the flush handle.
When activated, the flapper lifts and allows water to rush into the bowl and initiate the flush. If the flapper is damaged or worn out, it can cause leaks or continuous running water in the tank.
The Fill Valve
The fill valve is sometimes called a ballcock, which controls the refilling of the cistern after every flush. Connected to the water supply line, this valve opens to let water back into the tank and closes when the water reaches a preset level. Modern fill valves have an adjustable float or sensor to manage water levels more precisely, prevent overflow, and save water.
The Float Ball or Float Cup
The float ball (or float cup in newer models) is a buoyant device connected to the fill valve. This cup rises with the water level and signals the fill valve when to shut off the incoming water. Proper adjustment of the float ensures the cistern fills to the maximum level and maintains efficient flushing power without wasting water.
The Overflow Tube
The overflow tube works like a safety feature to prevent water from spilling over the edge of the cistern. If the fill valve or float fails stopping water from flowing in, the excess water flows through this tube and directly into the toilet bowl, and avoids flooding outside the tank. This tube maintains the cistern's water level and protects the bathroom from water damage.
The Trip Lever and Chain
The trip lever is the handle mechanism located outside the cistern. When pressed or lifted, it pulls a chain linked to the flapper valve, causing the flapper to lift and the flush to start. Over time, the chain can be stretched or disconnected, causing flushing problems. So, it often needs checking during repairs.
Refill Tube
The refill tube directs a small stream of water into the toilet bowl after a flush and replenishes the water that was used to clear waste. This small but essential part ensures the bowl remains clean and prevents odours.
