Before ordering, cross-reference this part number — 77707-0016 — directly against your heater's exploded parts diagram to confirm it matches your specific production run. While servicing the manifold, inspect the heat exchanger headers for scale buildup or corrosion, as both components are accessed during the same service procedure.\u003c\/p\u003e\u003c!-- wft:processed:manual:2026-03-30 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53912382046483,"sku":"77707-0016","price":568.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/PEN777070016_0.jpg?v=1772793735","url":"https:\/\/poolaroo.com\/products\/pentair_77707-0016","provider":"Poolaroo","version":"1.0","type":"link"}
