{"product_id":"hydro-skim-weir","title":"Pentair Weir Door for HydroSkim Skimmers","description":"\u003cp\u003ePentair 513352 is the weir door for HydroSkim skimmers. It is the genuine Pentair replacement for the hinged flap in the skimmer throat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the weir actually does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe weir is a small hinged door that floats against the water surface. By narrowing the skimmer opening, it makes water accelerate as it crosses the lip, and that faster sheet of water is what drags leaves and film off the surface instead of letting them drift past. When the pump shuts off, the weir falls closed and holds everything it collected inside the skimmer rather than releasing it back onto the pool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSigns it needs replacing\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLeaves that reappear on the surface after the pump stops, a flap that has cracked at the hinge, or a weir that no longer swings freely all point at this part. Before you order, confirm the water level sits around the middle of the skimmer mouth. A weir riding too high or too low cannot do its job no matter how good it is.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48635034599636,"sku":"PAC-251-3352","price":12.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_8b20098b-306b-4228-b5b6-bb0ffbdee5c0.png?v=1788839993","url":"https:\/\/www.activepoolsupply.com\/products\/hydro-skim-weir","provider":"Active Pool Supply","version":"1.0","type":"link"}
