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

The Viega ProPress 1" Zero Lead Check Valve with Double Press Connection and Smart Connect Technology is engineered for potable water distribution systems where backflow prevention and system integrity are critical. Designed for contractors, plumbers, and facility managers, this inline check valve eliminates the need for traditional soldering or threading, reducing installation time and labor costs while maintaining superior reliability in residential and commercial water supply applications.

Constructed from bronze with EPDM sealing materials, the check valve uses Viega's proprietary ProPress double press connection technology for fast, secure joints that require no flux, solder, or specialized training. The Smart Connect Technology integrated into this model ensures proper connection confirmation and eliminates installation guesswork, while the zero-lead brass construction complies with potable water regulations and NSF standards. The compact inline design allows straightforward integration into existing piping runs without excessive elbows or fittings.

This 1" check valve is ideal for new construction and retrofit applications where speed and code compliance matter equally. Plumbers specify it for horizontal and vertical installations, pump discharge lines, and pressure-side applications where backflow prevention is mandatory. The press connection system works seamlessly with standard 1" ProPress fittings and adapters, making it compatible with both copper and carbon steel systems. For municipalities, contractors, and DIY installers seeking reliable, lead-free backflow protection for sale or service upgrades, this Viega valve delivers proven performance backed by industry-leading warranty terms.
