Cash Acme EB45 Double Union 3/4 in NPT Female
The Cash Acme EB45 Direct Pressure Regulating Valve is a compact inline regulator designed for residential and light commercial use. Its half-cartridge design provides straightforward access to the pressure adjusting screw, enabling precise set-point changes without disassembly. The inline 3/4 in. NPTF double union configuration adds versatility for easy installation and maintenance. A tamper-resistant feature helps lock in the desired system pressure, protecting plumbing fixtures and appliances from overpressure while conserving water. Constructed with brass, stainless steel, and durable polymer components, this valve is built to resist corrosion and meet NSF/ANSI 372 for safe potable water use.
Key considerations for this model include compatibility with 3/4″ piping, reliable downstream pressure control, and the ability to service or adjust without disturbing surrounding connections. It is well-suited for homes where a secure, long-lasting solution is required to maintain stable water pressure and protect plumbing fixtures from surges and spikes.
Cash Acme EB45 Sweat Double Union 3/4 in
This 3/4 in. sweat (solder) version of the EB45 PRV offers a reliable, durable pathway for you to regulate downstream pressure in residential and commercial settings. Its double union design simplifies future servicing and replacement without disturbing the entire supply line. The tamper-resistant feature locks the regulator at the desired setting, reducing the risk of accidental changes. Built from brass, stainless steel, and robust polymers, this regulator meets drinking-water standards (NSF/ANSI 372) for safe water use. The sweat connection makes it an excellent choice for retrofit installs on copper piping systems.
Pros include straightforward solder connections, strong materials, and consistent downstream pressure. Consider this option if your home’s plumbing uses copper piping and you want a tamper-resistant, easy-to-service regulator with long-term durability.
Green Living Upgraded 3/4″ FNPT Double Union
The Green Living pressure regulator is designed for compact spaces with a short pipe diameter and easy rotation of the valve body to align with pre-fixed pipes. It provides a wide 10–70 PSI adjustment range suitable for both hot and cold water systems in residential or commercial environments. A clear water flow direction arrow helps with correct installation, and the dual-active FNPT interface simplifies positioning without twisting connected pipes. The valve uses a brass body, durable polymers, an integrated stainless steel filter, and includes a visible pressure gauge for real-time monitoring, helping maintain safe, steady pressure for appliances and fixtures.
Ideal for tight installations or retrofit projects where space is limited and real-time pressure feedback is valuable to monitor ongoing performance and protect plumbing infrastructure.
Cash Acme EB45 Single Union 3/4 in NPT Female x NPT Female
The EB45 single-union model provides convenient access to system pressure with a compact inline design. This variant features NPT female connections on both ends, simplifying alignment and installation in existing lines.

The product is NSF/ANSI 372 compliant for safe use with potable water, making it a reliable choice for households seeking dependable pressure control without compromising water quality or safety.
Watts Backflow Preventer 3/4 In Water Pressure Reducing Valve
The Watts lead-free water pressure reducing valve is designed to reduce pressure near meters and distribute safe pressure to appliances and outlets. It features an NPT union inlet and NPT female outlet, a removable stainless-steel strainer, a thermoplastic seat, and a bronze-sealed spring cage for outdoor or pit installations. Its thermal expansion bypass helps manage pressure surges caused by temperature changes. This model is intended for straightforward inline installation and serviceability, with a broad operating range that suits varied residential and commercial configurations while maintaining code-compliant performance and safety.
Buying Guide: Key Considerations And Comparisons
- Pressure range and adjustability: Residential regulators typically range from about 10–70 PSI to 25–75 PSI. Choose a model that matches your home’s typical demand and any appliance requirements (e.g., irrigation systems, boilers, or multi-story fixtures).
- Connection type: Match to existing piping—NPT, sweat (solder), or FNPT connections. Unions (single or double) simplify service and future maintenance.
- Tamper resistance: If you want to prevent accidental adjustments, select tamper-resistant designs with locking features.
- Materials and certifications: Brass bodies with stainless steel components offer durability and corrosion resistance. NSF/ANSI 372 compliance ensures suitability for potable water.
- Built-in gauges and indicators: Valves with integrated gauges provide real-time feedback on system pressure, enabling proactive adjustments and protection of appliances.
- Size and footprint: For retrofit projects in tight spaces, consider compact inline models or those with adjustable mounting orientations.
- Maintenance and serviceability: Look for models with easy access to adjustment screws, serviceable cartridges, and compatible replacement parts.
- Lead-free design: For compliance and safety, select lead-free options to minimize health risks in drinking water systems.
- Warranty and support: Good warranty terms and accessible customer support can be valuable for troubleshooting and long-term reliability.
In summary, the right residential water pressure valve should align with your piping configuration, pressure needs, and maintenance preferences. Whether you prioritize ease of installation, tamper resistance, or real-time pressure monitoring, there are options that balance performance with longevity, helping to stabilize home water pressure and protect plumbing components.
