Each one gives a threaded, sealed joint that comes apart by hand, so the pump can be removed for service or replacement without cutting into rigid pipe and rebuilding the plumbing afterward.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe usual failure\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eUnions leak in two ways. The o-ring hardens with age and heat until it no longer seals, or the nut has been cranked down with a wrench and cracked. Both are common, and both end with a replacement union. When you fit this one, thread the nut down by hand only; the joint is designed to seal on the o-ring, not on torque.\u003c\/p\u003e","brand":"Waterway","offers":[{"title":"Default Title","offer_id":48634021216468,"sku":"WWP-56-5990","price":14.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_81ac4b4a-839f-40b5-a13d-350e7d0eb0ad.jpg?v=1788824848","url":"https:\/\/www.activepoolsupply.com\/products\/2-5x2-pump-union-assembly","provider":"Active Pool Supply","version":"1.0","type":"link"}
