Featuring a 1\/2 inch NPT inlet connection and a brass body construction, this valve provides the internal plumbing infrastructure required before finish trim components are installed. Licensed plumbers install rough-in valves during the rough plumbing phase, prior to wall finishing, to establish water supply control points for shower systems. The brass body offers durability and corrosion resistance suited to potable water service environments.\u003c\/p\u003e\u003cp\u003eThis rough-in valve is intended for residential shower and tub-shower applications where a concealed in-wall valve body is required. It is installed during the rough-in stage of new construction or remodel projects, housed behind the finished wall surface. The 1\/2 inch NPT inlet sizing is standard for residential water supply lines, making it compatible with typical residential plumbing configurations. Finish trim kits are purchased separately and installed over the valve body once wall finishing is complete.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass body construction for corrosion resistance in potable water applications\u003c\/li\u003e\n\u003cli\u003e1\/2 inch NPT inlet connection matches standard residential supply line sizing\u003c\/li\u003e\n\u003cli\u003eDesigned for concealed in-wall installation during rough plumbing phase\u003c\/li\u003e\n\u003cli\u003eAccepts separately sold finish trim components for design flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style rough-in valve for use with compatible DELTA FAUCET trim kits and shower system components requiring the R3500 valve platform.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the main water supply and depressurize the supply lines before beginning work. The valve must be secured and properly positioned within the wall cavity at the correct depth to allow for the finish trim plate to seat flush against the finished wall surface. Do not apply thread sealant or pipe tape to NPT connections until the valve orientation and depth are confirmed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 1\/2 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DELTA FAUCET\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R3500-WL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELTA FAUCET","offers":[{"title":"Default Title","offer_id":51524808540466,"sku":"DLR3500-WL","price":207.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2134cc9773740c0480b0a65359c0b6c.jpg?v=1785458168","url":"https:\/\/voomisupply.com\/products\/delta-faucet-r3500-wl-rough-in-valve-1-2-in-npt-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
