It threads into the wall return and directs the water coming back from the equipment pad.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the sizes do\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 1-1\/2 inch MPT is simply how the fitting mounts. The 3\/4 inch figure is the part that changes how the pool behaves: narrowing the outlet raises the speed of the water leaving it, so the stream carries further into the pool and does more to keep the surface turning over instead of stalling near the wall.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace one\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eEyeballs live in sun and sanitizer and eventually go brittle. A cracked flange or a ball that no longer holds its position lets the return wander, and the pool ends up with dead corners. Swapping the fitting is a hand job at the wall, no tools past a firm grip.\u003c\/p\u003e","brand":"Waterway","offers":[{"title":"Default Title","offer_id":48634173161684,"sku":"WWP-25-1712","price":6.6,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_a44a51f2-d2b9-4959-a268-b091895cb078.jpg?v=1788826263","url":"https:\/\/www.activepoolsupply.com\/products\/3-4-eyeball-fitting-gray","provider":"Active Pool Supply","version":"1.0","type":"link"}
