Viega ProPress 3/4" Zero Lead Check Valve - Double Press Connection - Smart Connect Technology

The Viega ProPress 3/4" Zero Lead Check Valve with Double Press Connection and Smart Connect Technology is a lead-free bronze check valve engineered for potable water systems in residential and commercial applications. This press-connection check valve delivers reliable backflow prevention while maintaining drinking water safety standards, making it an essential component in modern plumbing installations where potable water protection is critical.

The 3/4" valve features Viega's Smart Connect Technology, which simplifies installation by eliminating guesswork during press operations. Bronze construction provides corrosion resistance and longevity in typical water service environments. The double press connection design ensures secure, repeatable joints without solder, flux, or additional fittings—reducing labor time and potential leak points. EPDM sealing elements maintain water-tight performance across standard plumbing temperature and pressure ranges. The inline orientation allows straightforward integration into horizontal or vertical pipe runs, and the check valve's low-cracking pressure design minimizes water hammer while allowing normal flow rates.

This check valve is specified by plumbers and installers in new construction and retrofit applications where code-compliant backflow prevention is required. Municipalities increasingly mandate lead-free components in potable water lines, making zero-lead valves the standard choice. The ProPress system's press connection method has become the preferred alternative to soldering in professional plumbing, offering faster installation, reduced fire risk, and consistent joint quality. The Smart Connect feedback feature helps installers verify proper pressure application without additional gauges.

Viega's ProPress technology is recognized across the plumbing industry for reliability and ease of use. The 3/4" size covers a common residential and light commercial demand, fitting standard water service piping. Whether upgrading aging plumbing to lead-free standards or installing new systems, this check valve combines code compliance, durability, and installation efficiency.
