{"product_id":"air-relief-assembly","title":"Hayward Air Relief and Gauge Adapter Assembly","description":"\u003cp\u003eThe Hayward DEX2400S is the air relief and gauge adapter assembly that sits on top of the filter. It does two jobs: it vents air trapped in the tank, and it provides the port the pressure gauge threads into.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy the bleed matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAir works its way into the tank whenever the system is opened, and it collects at the top where it cushions the water. That air throws off the pressure reading you use to decide when to clean, and it puts an unnecessary load on the lid and clamp. Opening the relief while the pump starts pushes it out, and once water appears the valve is closed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eHayward lists this assembly for the Micro-Clear DE filters and the Super Star-Clear cartridge filters, and also catalogs it with Pro Series side mount sand filter parts for the S-311SX, S-311SXV and S-360SX.
