Once you've verified flow is correct and the switch still fails to close, this OEM replacement restores the original switching threshold. Always shut off power to the heater at the breaker before disconnecting or reconnecting any electrical components. Have a licensed pool technician perform the replacement if you are not certified to work on mains-voltage pool equipment.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-22 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54303485460755,"sku":"CZXPRS1105","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-pressure-switch-for-pool-and-spa-heaters-czxprs1105.webp?v=1785744844","url":"https:\/\/poolaroo.com\/products\/hayward_czxprs1105","provider":"Poolaroo","version":"1.0","type":"link"}
