Viega ProPress 1-1/2" Zero Lead Check Valve - Double Press Connection - Smart Connect Technology

The Viega ProPress 1-1/2" Zero Lead Check Valve with Double Press Connection and Smart Connect Technology is a lead-free bronze check valve engineered for potable water systems. This inline valve prevents backflow through press-fit connections, meeting modern drinking water standards while delivering reliable flow control in residential and light commercial plumbing applications.

The 1-1/2" size accommodates moderate flow demands typical in multi-fixture residential lines or small commercial circuits. Bronze construction provides corrosion resistance in wet environments, while EPDM sealing elements ensure long-term integrity without degradation from potable water exposure. The double press connection design eliminates threading and soldering, reducing installation time and material costs compared to traditional methods. Smart Connect Technology integrates with Viega's proprietary press system to verify proper connection closure, preventing installation errors that compromise system performance.

This check valve is specified in new construction and renovation projects where lead-free compliance is mandatory and backflow prevention is required by code. Plumbers and mechanical contractors rely on Viega's press connection systems to accelerate rough-in schedules while maintaining ICC and NSF compliance. The inline configuration integrates seamlessly into existing supply line layouts without requiring additional fittings or elbows.

Viega ProPress check valves are recognized in the plumbing industry for consistent performance across thousands of installations. The press connection method has become standard in professional plumbing because it eliminates flux, solder joints, and fire hazards on active water systems, while reducing labor time on the jobsite.
