{"product_id":"adjustable-water-pressure-switch","title":"Jandy Adjustable Water Pressure Switch","description":"\u003cp\u003eThe Jandy R3001000 is the adjustable water pressure switch used on Jandy heat pumps. It is the genuine Jandy part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA heat pump must never fire without water moving through it. The pressure switch is the device that proves that flow: it senses water pressure in the unit and closes a circuit that tells the control it is safe to start. Everything downstream of that, from the compressor to the heat exchanger, depends on the switch being honest.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAdjustable trip point\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis version is adjustable, so the pressure at which it makes and breaks can be set rather than left at a factory fixed value. That is useful where pipe runs, pump sizing or elevation give a pressure at the unit that a fixed switch reads badly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt is listed as a replacement part for the Jandy EE-Ti heat pumps, and Jandy parts listings also carry it against the AE-Ti series. Check the model number on your unit against both before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDiagnosing it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA heat pump that reports no flow while the pump is clearly running points at either a genuine flow restriction or a failed switch. Check the filter, the valves and the strainer basket first, because a switch doing its job correctly looks identical to a broken one until you rule out the real causes.\u003c\/p\u003e","brand":"Waterpik Technologies","offers":[{"title":"Default Title","offer_id":48634022199508,"sku":"AEH-151-1008","price":103.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_1d64064f-8798-4a86-9787-e738d7e8e56a.jpg?v=1788824863","url":"https:\/\/www.activepoolsupply.com\/products\/adjustable-water-pressure-switch","provider":"Active Pool Supply","version":"1.0","type":"link"}
