Addressing those conditions during the same service visit avoids repeat teardown. Always have a licensed pool professional or HVAC technician perform this repair — heater manifold work involves both water pressure and gas or high-voltage electrical systems.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-05-01 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":52770060468499,"sku":"77707-0207","price":117.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-manifold-internals-200000-btu-heater-parts-77707-0207.webp?v=1767397803","url":"https:\/\/poolaroo.com\/products\/pentair-manifold-internals-200-000-btu-heaters-77707-0207","provider":"Poolaroo","version":"1.0","type":"link"}
