This sanitary fitting merges the flow geometry of a tee and a wye into a single body, producing a smoother directional transition than a standard tee. The hub-by-hub-by-hub connection configuration accepts solvent-welded socket joints on all three ports. Licensed plumbers install this type of fitting in residential and light commercial drain and vent assemblies where a 4-inch main line requires a branch takeoff.\u003c\/p\u003e\u003cp\u003eThe combination tee-wye is a common choice in DWV rough-in work where long-radius flow paths are required to meet drain slope and velocity requirements. It is used in horizontal-to-horizontal and horizontal-to-vertical branch configurations in gravity-drain piping. The 4-inch size is standard for main building drains, closet flanges, and large fixture branches in residential construction and commercial retrofit plumbing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLong-radius sweep geometry reduces flow restriction and supports self-scouring drain velocity\u003c\/li\u003e\n\u003cli\u003eCombination tee-wye body handles both tee and wye branch configurations in a single fitting\u003c\/li\u003e\n\u003cli\u003eHub x Hub x Hub (H x H x H) ends accept standard solvent-cement socket connections\u003c\/li\u003e\n\u003cli\u003e4-inch diameter suits main building drains, toilet branches, and large fixture lines\u003c\/li\u003e\n\u003cli\u003eDWV-rated construction appropriate for gravity-drain and vent piping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style DWV fitting compatible with standard 4-inch hub-end pipe and fittings used in residential and commercial drain, waste, and vent systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. All flow lines should be shut off and the system depressurized before cutting into an existing drain stack. Clean and dry all hub surfaces thoroughly before applying solvent cement, and observe manufacturer cure times before restoring flow. Verify branch slope and fitting orientation comply with local DWV slope requirements before securing the fitting in place.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Hub x Hub x Hub (socket)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Pattern\u003c\/strong\u003e: Long Radius Combination Tee-Wye\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Drain, Waste, and Vent (DWV)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MUELLER STREAMLINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PDWVCOMBY4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51524581753138,"sku":"PDWVCOMBY4","price":50.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56d75d117407addbd68230dd281e2e97_6f9d7833-4807-4bea-b56a-47611950a617.jpg?v=1785452345","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-pdwvcomby4-combo-tee-wye-4-in-hub","provider":"Voomi Supply","version":"1.0","type":"link"}
