Cash Acme 1/2 in. Bronze Temperature and Pressure Relief Valve

The Cash Acme 1/2 in. Bronze Temperature and Pressure Relief Valve is a critical safety component designed to protect hot water systems from overheating and overpressure. With a durable bronze body and a fixed 210°F temperature relief setting, this valve delivers reliable protection without the need for field adjustments.

Key features that stand out

• Bronze body for long-lasting durability and corrosion resistance in hot water environments.
• Inlet size 1/2 in. compatible with standard residential connections for easy integration.
• Fixed relief at 210°F and non-adjustable operation to provide predictable safety performance.
• Temperature and pressure relief—it automatically vents when either the temperature or pressure exceeds safe levels, helping prevent tank damage and scalding incidents.
• Leaded construction and material composition suitable for legacy systems; check local codes for potable water suitability and compliance.

What problems it solves

When a hot water system experiences a surge in temperature or pressure, the Cash Acme T&P Valve opens to release water, reducing risk of tank rupture, boiler damage, or scald hazards. Its non-adjustable 210°F setting provides a clear, factory-calibrated protection point, so you don’t have to worry about miscalibrating the relief threshold.

Ideal applications

• Residential domestic hot water heaters and storage tanks
• Boilers and hydronic heating systems that require reliable temperature and pressure protection
• Older plumbing setups that benefit from a robust bronze relief valve with proven performance

Why this valve stands out

Compared to generic plastic or lower-grade components, the bronze body of the Cash Acme valve delivers superior durability in hot-water environments and helps resist corrosion over time. Its 1/2 in. inlet sizing aligns with common plumbing configurations, ensuring compatibility with a wide range of installations. The combination of temperature and pressure relief in a single, non-adjustable unit provides straightforward safety, minimizing maintenance hassles while maintaining strong protection for your water heating system.

Tips for installation and care

Place the valve on the highest point of the heater or system with a downwardly directed discharge line to a safe location. Regularly test the valve according to local codes to confirm proper operation, and never cap or obstruct the discharge outlet. If your system is part of a potable water supply, verify that the leaded construction complies with local plumbing codes and replacement intervals.
