It joins pipe to a threaded equipment port in a way that can be taken apart again.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a union buys you\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA glued coupling is permanent. A union is not: the collar backs off and the joint separates, so a pump, filter or heater can be pulled off the pad for service without a saw and a rebuild of the plumbing. Fitting unions at the equipment is what turns a half day repair into a short one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCPVC and where it belongs\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCPVC handles higher water temperature than standard PVC, which is why it gets specified on hot side plumbing and around spa equipment. It installs the same way, but it needs solvent cement made for CPVC, not ordinary PVC cement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting notes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSolvent weld the socket end to clean, deburred 1-1\/2 inch pipe. On the threaded end, seal the thread and tighten by hand plus a small turn. Plastic threads strip and crack when they are wrenched down hard, and a union that is snug does not need to be tight.\u003c\/p\u003e","brand":"CMP","offers":[{"title":"Default Title","offer_id":48634262913236,"sku":"CTM-56-2000","price":15.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/21063-150-000_3.jpg?v=1788827865","url":"https:\/\/www.activepoolsupply.com\/products\/1-1-2-union-sktxmip-cpvc","provider":"Active Pool Supply","version":"1.0","type":"link"}
