At the \u003cstrong\u003eDIY Hardware Store\u003c\/strong\u003e, our rectangular syphon and ball valve range covers the cistern components used in standard UK domestic toilet maintenance and repair.\u003c\/p\u003e\n\n\u003cp\u003eA toilet that runs continuously, fails to flush powerfully, or takes an excessively long time to refill typically has a faulty syphon or fill valve (ball valve). The rectangular syphon creates the flush by lifting its internal flap valve, generating a siphonic action that empties the cistern rapidly into the pan. When the syphon diaphragm wears or tears, the flush becomes weak or fails entirely - a straightforward repair with the correct replacement syphon.\u003c\/p\u003e\n\n\u003cp\u003eThe fill valve (ball valve or float valve) controls cistern refilling after a flush.
