Safety Valve for Water Heater TDM_BRASS 119 (model 119034) with Nose — Pressure Relief Valve

The Safety Valve for Water Heater TDM_BRASS 119 with Nose is a pressure relief valve designed to protect storage and tank-type water heaters from excessive pressure. The valve opens at a set pressure to discharge excess water or steam through a controlled nose outlet, preventing damage to the heater, piping and connections. It is supplied as a compact mechanical safety device intended for installation or replacement on residential and light commercial boilers and storage heaters.

Advantages

This pressure relief valve provides reliable overpressure protection through a mechanical spring-loaded mechanism that operates without electrical power. The nose outlet design ensures a directed and controlled discharge path, reducing the risk of water spray or accidental contact. Constructed from corrosion-resistant materials suitable for contact with domestic hot water, the valve is compact and compatible with common heater mounting arrangements, simplifying replacement and installation.

Suitable for

• Domestic storage water heaters and tank boilers
• Replacement of existing safety/pressure relief valves on residential units
• Light commercial hot water systems with compatible connection and set pressure
• Applications requiring a directed discharge outlet for safe drain routing

Key specifications

• Function: spring-loaded pressure relief / safety valve
• Discharge outlet: nose (directed outlet for controlled discharge)
• Application: storage and tank-type water heaters and boilers
• Material characteristics: corrosion-resistant metal suitable for potable hot water contact
• Operation: mechanical, no external power required

How to use

Install the valve in the designated safety discharge port on the water heater following the heater manufacturer’s instructions and local plumbing regulations. Ensure the valve orientation allows free discharge through the nose outlet to a safe drain or designated discharge pipe. Check sealing surfaces and use appropriate thread sealant or gasket if required; tighten to recommended torque to avoid leaks or distortion. After installation, pressurize the system and inspect for leaks. Verify the valve operates by observing discharge when system pressure exceeds the valve’s set point or by performing a manual lift test if permitted by local codes.

Usage recommendations

Periodically inspect the valve and discharge path for corrosion, blockages or leaks. Replace the valve if signs of impaired operation appear or at intervals recommended by the heater manufacturer. Do not block the discharge outlet; route the discharge to a safe location and ensure downstream piping meets applicable codes.
