The Watts 3/4" T&P Relief Valve is engineered to safeguard storage water heaters and hot water supply tanks by automatically discharging when temperature or pressure exceeds safe system limits. With dual functionality and factory-set performance parameters, this valve delivers dependable protection against overpressure and overheating—critical factors in preserving system integrity and safety.
Designed with lead-free copper alloy for compliance in potable water systems, the valve includes a precision thermostat element and high-capacity discharge for reliable operation in demanding environments. This model meets all applicable ASME and CSA performance standards for T&P relief applications.
This valve must be installed directly into the designated relief port of a water heater or hot water tank. A discharge pipe must be attached and piped to a safe drain point per local plumbing code. While installation is generally straightforward, improper orientation or discharge line routing can impair functionality. For safety and compliance, installation should be completed by a licensed professional familiar with pressure relief system requirements.
This is a high-quality, code-compliant T&P valve trusted for new construction and replacement jobs alike. Its proven field performance and ease of installation make it a preferred choice for hot water system protection. Stock it for service calls and spec it with confidence on tank installs.
If performing routine equipment upgrades or preventative maintenance on-site, this relief valve is an ideal replacement component. Check valve age, signs of mineral buildup, and test the release lever annually to confirm proper function. Always verify compatibility with tank capacity and rating labels.
The Watts 3/4" Temperature and Pressure Relief Valve is a critical component for maintaining the safety of any pressurized hot water system. Built from quality materials and certified to industry standards, it offers peace of mind and long-term performance in both residential and commercial applications.
