Flush valves and syphons for toilet cistern repairs

Find flush valves and syphons for toilet cistern repairs and replacements, including dual flush valves, toilet syphons, cistern flush mechanisms and replacement flush valve parts.

Flush valves and syphons control the flush from the cistern into the toilet pan. If the toilet will not flush correctly, keeps running, or has a worn flush mechanism, replacing the correct part may solve the issue.

Before ordering, check the cistern height, outlet size, button or handle type, and whether your toilet uses a flush valve or traditional syphon.
