Installation Guidance

This valve is intended for installation in systems that require a pressure relief mechanism due to closed-system thermal expansion. It can be installed vertically or horizontally, as long as the discharge is piped to a safe drainage location. Proper installation ensures safety compliance and long-term valve performance.

Due to the critical nature of relief valve performance, it’s recommended that a licensed plumbing contractor handle installation. Improper application or misalignment could result in operational issues or system failure.

Contractor Notes

• Ensure valve orientation matches system requirements and local codes.
• Use approved discharge piping sized appropriately for pressure relief flow.
• Verify relief setting is compatible with system design pressure.

Final Word

For contractors seeking a reliable, field-tested solution to thermal expansion protection, the Cash Acme 3/4" Bronze Pressure Relief Valve is a trusted component. Its rugged build and precision-tested performance make it ideal for safeguarding hot water systems across residential and light commercial settings.
