This diaphragm forms a flexible, pressure-responsive seal inside the valve, allowing it to correctly divert hot water to the DHW circuit when there is demand at a tap or shower. Over time, diaphragms can harden, stretch, or deteriorate, which can lead to erratic hot water flow or valve sticking; replacing it with this genuine kit helps restore smooth and reliable operation.\u003c\/p\u003e\n\u003cp data-end=\"860\" data-start=\"583\"\u003eThis diaphragm replacement kit is compatible with \u003cstrong data-end=\"661\" data-start=\"633\"\u003eBaxi combi boiler models\u003c\/strong\u003e that require the 5111137 specification for their DHW control valve.
