Engineered for hot water storage tanks and water heaters, the Watts 3/4" Automatic Reseating Temperature and Pressure Relief Valve is built to safeguard closed water heating systems from excess pressure or temperature. This valve provides reliable overpressure discharge while automatically reseating once normal operating conditions are restored—eliminating the need for manual reset or replacement in most events.
Its construction from lead-free copper silicon alloy meets stringent potable water standards, and its precision thermostat ensures accurate operation when critical thresholds are exceeded. Designed for both residential and commercial systems, this T&P relief valve combines safety, code compliance, and long-term performance.
Install vertically on the tank’s top outlet or designated relief port with the discharge tube piped to an approved drain. Proper orientation and sizing of the drain line are critical to ensure full flow and avoid backpressure. Though the process is straightforward, professional installation is recommended to confirm code compliance and safety performance, especially in commercial or multi-unit settings.
Contractor Benefits: This valve is factory-calibrated for consistent operation and built to meet ASME and CSA requirements. Its reseating function reduces maintenance calls, while the durable alloy body stands up to harsh conditions in mechanical rooms and service areas.
Installer Tips: Ensure valve threads are clean and properly sealed during installation. Always test the valve function after system commissioning, and inspect annually as part of routine water heater maintenance.
Backed by decades of field performance, the Watts 3/4" Automatic Reseating Temperature and Pressure Relief Valve is a critical safety component for any hot water system. Whether you're specifying a new installation or replacing an older model, this valve delivers trusted protection with the added benefit of automatic reseating for reduced service disruption. Install with confidence—Watts sets the standard in system safety.
