HYDRO MASTER Tankless Water Heater Service Valve Kit – 3/4 IPS, Lead-Free Brass, 150 PSI PRV

Overview

Upgrade or refresh your tankless water heating setup with the HYDRO MASTER Tankless Water Heater Service Valve Kit. Built for reliability, this all-in-one solution combines heavy-duty brass components with precise valve control to support smooth hot water delivery in real homes.

Durable brass construction

Crafted from thick, forged lead-free brass, the kit is designed to resist wear and potential leaks in busy kitchens and baths. Each valve set undergoes factory testing to help ensure long service life and consistent performance in demanding environments.

• Thick, forged lead-free brass for strength and leak resistance
• Factory-tested components for reliability before installation

All-in-One kit for better flow and safety

The package includes hot and cold isolation valves (500WOG), a pressure relief valve rated at 150 PSI / 200,000 BTU, and full-port ball valves that maximize water flow. Together, these parts support smoother operation and potentially improved system efficiency in daily use.

• Hot and cold isolation valves (500WOG) for simple service access
• Pressure relief valve rated 150 PSI / 200,000 BTU for pressure protection
• Full-port ball valves to minimize flow restriction

Wide compatibility and easy installation

Designed to fit standard 3/4 inch IPS connections and compatible with leading tankless brands such as Rheem, Rinnai, EcoSmart, Navien, and more. Color-coded handles help distinguish hot and cold lines for fast, error-free use during installation and maintenance.

• Fits standard 3/4 IPS connections across major brands
• Color-coded handles aid quick, error-free setup

Safety, standards, and reliability

The kit complies with federal and state standards for lead content in drinking water system components and carries CSA certification. This focus on material safety and quality control helps support confident installation in homes.

While this kit is designed to support easier service and better flow, results can vary based on your specific system, existing fittings, and installation conditions. Consider it a robust frame for reliable operation rather than a guaranteed performance claim.

Real-world scenarios and maintenance tips

Ideal for replacing aging isolators, upgrading to full-port valves, or standardizing components across multiple zones in a home. For best results, periodically inspect connections for leaks and keep fittings clean to maintain ease of use and longevity.
