If your Powermax heater is failing to fire, shutting down unexpectedly, or displaying a flow-related fault, this kit addresses the flow switch assembly responsible for verifying water movement before allowing ignition.\u003c\/p\u003e\n\n\u003cp style=\"background-color: #fff3cd; border: 2px solid #FFEAA7; padding: 15px; border-radius: 5px; margin: 15px 0; color: #856404;\"\u003e\n\u003cstrong\u003e⚠️ IMPORTANT: KIT LISTING\u003c\/strong\u003e\u003cbr\u003e\nThis listing is a kit — not a single component.

Do not attempt to service gas or high-voltage components without proper certification.\n\u003c\/p\u003e\n\n\u003cp\u003eThe flow switch is a safety-critical component in the Powermax heater's control circuit. It signals the control board that adequate water flow is present before the heater is permitted to ignite. A failed or stuck flow switch can cause nuisance shutdowns, prevent the heater from firing entirely, or — if stuck in the closed position — allow the heater to operate without confirmed flow, risking heat exchanger damage. Replacing the complete kit restores reliable flow detection and protects the heater from dry-fire conditions.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\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;\"\u003eRE0013000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eDescription\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eOutdoor Flow Switch Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eQuantity Included\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eKit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, locate the part number on your existing flow switch assembly or in the Powermax heater's parts diagram. Flow switch configurations can vary by heater model revision — confirming RE0013000 against your equipment's service manual or the number on the original component is the most reliable way to ensure correct fitment. Have a licensed technician inspect the flow switch wiring and plumbing connections during replacement, as adjacent components are often due for inspection at the same service interval.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-04 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53954271707411,"sku":"RE0013000","price":366.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-flow-switch-kit-powermax-pool-spa-heater-re0013000.webp?v=1781081231","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_re0013000","provider":"Poolaroo","version":"1.0","type":"link"}
