Knowing what you need is half the challenge when it comes to toilet repairs. Explore the toilet flusher parts we supply and their role in cistern systems.

Responsible for bringing water into the bowl to wash away waste, toilet flush valves are an essential part of the cistern. Signs that a flush valve is failing include constantly running water or no response when the flush button or handle is pressed.

Check for damage to the flapper that seals the flush valve opening. If this looks to be in good shape, it's likely you need a new valve.

A dual-flush valve is a popular choice. This gives you the option to choose between a half or full flush, optimising your water use and saving money. 

Is your problem related to the water in your cistern? This could be due to a faulty fill valve. A fill valve in need of replacement may not allow the tank to fill to its required level, resulting in a weak flush. And when a toilet takes longer to refill after a flush, it’s a sign that the fill valve is not working correctly.

We stock various styles including ball valves, flats and flapper valves, in a range of lengths and sizes to suit all cistern shapes.

For problems that don't require a system overhaul, we sell toilet flush parts including syphons, flushpipes, levers and floats.
