Always confirm your valve model before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eWhy do I need to replace my MPV unions?\u003c\/h3\u003e\n\u003cp\u003eUnion connections on multiport valves are a common source of leaks as O-rings age, crack, or deform. Replacing the full union set restores a watertight seal and prevents water loss around the valve ports.\u003c\/p\u003e\n\n\u003ch3\u003eDoes this pack include O-rings?\u003c\/h3\u003e\n\u003cp\u003eYes — the pack includes both threaded union O-rings and tail union O-rings for all three ports, so you have everything needed for a complete reseal.\u003c\/p\u003e\n\n\u003ch3\u003eIs this suitable for DE filters as well as sand filters?\u003c\/h3\u003e\n\u003cp\u003eYes, but for DE filters you must confirm the valve size is 20-SP0715XR50 before ordering. Compatible DE models include DE2420, DE3620, DE4820, DE6020, and DE7220.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need a plumber to replace Hayward MPV unions?\u003c\/h3\u003e\n\u003cp\u003eIn most cases this is a DIY-friendly job. Turn off the pump, depressurise the system, unscrew the old unions, and fit the new ones. If your plumbing is glued rather than threaded, you may need a licensed plumber to cut and re-join the pipe.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":50009104285971,"sku":"SP24X50AUUNPAK","price":89.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/0591\/1827\/files\/HaywardMPVUnionKit_50mm.webp?v=1729472920","url":"https:\/\/poolshop.com.au\/products\/hayward-mpv-union-50mm-set-of-3","provider":"Pool Shop Australia","version":"1.0","type":"link"}
