Fitted at a high point in the system, it keeps working quietly in the background, releasing air as it accumulates and helping the whole system run more efficiently.\u003c\/p\u003e\n\n\u003cp\u003eInside, a \u003cstrong\u003efloat-operated valve mechanism\u003c\/strong\u003e does the work: as air collects inside the float chamber, the float drops and opens the valve, releasing the trapped air.
