MEASUREMAN Tankless Water Heater Service Valve Kit — 3/4 IPS Forged Brass Isolators with 150 PSI Pressure Relief, Lead-Free

Meet the MEASUREMAN Tankless Water Heater Service Valve Kit, a durable, lead-free brass solution designed to simplify maintenance, installation, and safe operation across most 3/4-inch tankless systems. Built for everyday use in homes and small commercial spaces, this kit combines rugged construction with thoughtful details that help you manage water flow and service access with confidence.

Crafted from certified lead-free brass, the kit resists corrosion and maintains lasting performance in fluctuating water conditions. The full-port ball valves reduce resistance for steady, efficient flow, while color-coded red and blue handles offer quick hot and cold identification during busy maintenance windows. A CSA-certified 150 PSI pressure relief valve adds a layer of safety by guarding against overpressure scenarios, helping you stay compliant with regulations and avoid unnecessary disruption to the system.

What you get

• 3/4" IPS forged brass isolator valves with full-port design for efficient flow
• CSA-certified 150 PSI pressure relief valve for overpressure protection
• Lead-free brass construction that meets federal and state potable water standards
• Color-coded red (hot) and blue (cold) handles for quick identification
• Integrated drain valve with brass cap for quick flushing
• Threaded connections for solder-free installation and easy maintenance

Why this matters in practice

• Real-world maintenance becomes faster: isolate a line, drain a loop, and service without shutting down the entire system.
• Durable brass and corrosion resistance offer confidence in harsh water conditions and frequent use.
• The color-coded handles reduce the chance of cross-connection errors during aging or repairs.

Real-world scenarios and applications

In seasonal maintenance, you can isolate the heater loop to perform a cleaning flush during periods of low demand. In tight mechanical spaces, the compact valve arrangement fits neatly without sacrificing performance. The 150 PSI relief valve serves as a safeguard during startup surges, while the integrated drain valve enables rapid testing and drainage without a full system shutdown.

Installation and care tips

Because the kit uses threaded connections, you can perform a solder-free upgrade with standard wrenches. Use appropriate sealing practices and follow local codes. Regular flushing through the drain valve helps minimize mineral buildup and supports long-term reliability. Inspect joints periodically for leaks and replace worn washers as needed.

Material, build quality, and long-term value

The combination of lead-free brass construction and CSA certification underscores a focus on durability and regulatory compliance. The full-port design minimizes flow resistance, supporting steady performance under varying demand. Color-coded handles enhance usability in busy maintenance scenarios, offering a practical benefit for technicians and homeowners alike.
