Ideal For: Flushing & descaling tankless water heaters. Isolating the unit for repairs without disrupting household water supply. Preventing pressure-related damage with the built-in relief valve. Installation Tips: Use Teflon tape or pipe sealant on threads for a leak-free fit. Ensure the pressure relief valve faces downward for proper drainage. Periodically test the relief valve to ensure it functions correctly.

  • Compatibility – Fits most 3/4" MNPT tankless water heaters (electric & gas).
  • Service Ball Valves – Allows isolating the heater for maintenance without shutting off the whole water supply. Color-coded handles (red = hot, blue = cold) for easy identification.
  • Pressure Relief Valve (150 PSI) – Prevents dangerous pressure buildup in the hot water line, enhancing safety.
  • Easy Installation – Threaded connections (no soldering needed) + openable brass cap for quick hose attachment during flushing.
  • Durable Brass Construction – Made from lead-free, CSA-certified brass for heat & corrosion resistance, ensuring long-term reliability.
