The mechanical seal is what makes that possible: a spring loaded face turning against a fixed ceramic seat, polished flat enough to hold water back while the shaft spins. It is a wear part by design.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow you know it has failed\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWater appears at the joint between the pump housing and the motor, usually as a drip that gets worse over a season. Once it starts, the water runs along the shaft toward the motor bearings, so this is not a leak to live with. Replace the seal as a matched pair, rotating face and seat together, and check the shaft and the seal plate for scoring while everything is apart.\u003c\/p\u003e","brand":"US Seal","offers":[{"title":"Default Title","offer_id":48634965590228,"sku":"USS-60-5018","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_ad2e3015-c728-47cb-bb14-017c2f90a7ab.jpg?v=1788839132","url":"https:\/\/www.activepoolsupply.com\/products\/ps100-seal-assembly","provider":"Active Pool Supply","version":"1.0","type":"link"}
