Zurn Wilkins 114-NR3XLDUC 1-1/4 in NR3XL Pressure Reducing Valve

In this review of the Zurn Wilkins 114-NR3XLDUC pressure reducing valve, the bottom line is simple: it is a compact, serviceable PRV built for residential and light commercial plumbing where space and maintainability matter. The valve's short lay length and cartridge-loaded design make installation and future servicing straightforward, while the integral stainless steel strainer protects downstream fixtures from sediment. If you need a durable PRV that saves time on repairs and helps conserve water, this model is a practical choice for contractors and property owners alike.

Key Features

• Compact design: The short lay length and compact construction allow installation in tight mechanical rooms and under slab or cabinet spaces where longer valves would not fit.
• Cartridge-loaded repair: The removable cartridge simplifies maintenance and repair, reducing downtime and labor compared with fully integral designs.
• Multiple tailpiece options: Threaded, PEX, copper sweat and CPVC tailpiece options speed installation on a variety of supply systems and reduce the need for adapters.
• Stainless steel strainer: The quality integral stainless steel strainer screen captures sediment and debris to protect downstream valves and fixtures without frequent clogging.
• Corrosion resistance: The threaded bell construction is designed to resist corrosion and provides quick access to the cartridge for cleaning or replacement.
• Code compliant: The unit meets common plumbing standards, making it suitable for residential, multifamily and landscaped site installations where listing is required.

Who It's For

The NR3XLDUC is aimed at plumbers, contractors and building owners who need a compact, serviceable pressure reducing valve for single-family homes, multifamily projects, landscaped water systems and public entrances. Its short lay length and range of tailpiece options make it a good fit where space is limited or when connecting to existing copper, PEX or threaded systems.

Those seeking a decorative fixture or an electronic pressure control should look elsewhere; this model is a mechanical PRV focused on durability and ease of maintenance rather than smart controls or ornamental finishes. Also, installers who require unions with pre-cut threads in both union ends should verify union configuration during purchase, as some customers have noted thread-related issues.
