This wye-pattern assembly is supplied with union ball valve shutoffs and a bronze Y-type strainer to simplify isolation, maintenance, and debris protection.\u003c\/p\u003e\n\u003cp\u003eThis assembly is ideal for irrigation, landscape, and other non-potable water systems where code-compliant reduced pressure protection is required. The union ball valves and Y-strainer make routine testing and maintenance faster, and the bronze body helps ensure long-term reliability in outdoor and mechanical-room installations. For installation, follow local plumbing codes and the manufacturer's specification sheet for testing intervals, orientation, and service procedures.\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e 975XLU (Wilkins) — compact wye-pattern bronze body for
