When adequate flow is detected, the switch signals the control board to allow chlorine generation to proceed; when flow is insufficient, it interrupts the chlorination cycle to protect the cell. A failed or fouled flow switch is a common cause of \"no flow\" fault codes on IntelliChlor systems even when the pump is running. This assembly includes four watertight splice connectors for a weatherproof field connection.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e520736\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, confirm 520736 matches the part number printed on your existing flow switch or listed in your IntelliChlor installation manual. When replacing the flow switch, inspect the splice connections at the same time — the four included watertight connectors are intended for a clean, corrosion-resistant reinstall and should be used rather than reusing aged field wiring connections.\u003c\/p\u003e\n\u003c!-- DRAFT STATUS --\u003e\u003c!-- wft:processed:manual:2026-03-30 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53912382308627,"sku":"520736","price":244.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/PEN520736_0.jpg?v=1772793749","url":"https:\/\/poolaroo.com\/products\/pentair_520736","provider":"Poolaroo","version":"1.0","type":"link"}
