Product Details

Rinnai Water Heater Valve Kit For Tankless Water Heater Manifolding REU-PVA-4

The Rinnai REU-PVA-4 is a genuine OEM pressure-activated valve designed for manifolding multiple Rinnai tankless water heaters together in a single system. Installed between paired units, this mechanical valve uses water pressure to automatically activate additional heaters as demand increases. This allows systems with two to five units to maintain consistent water temperature while improving efficiency and load distribution. Built to Rinnai’s quality standards, the valve helps ensure reliable operation and smooth sequencing of tankless water heaters in multi-unit installations.

Key Features

  • Pressure Activated Valve – Automatically activates additional water heaters in a manifolded system as water demand increases
  • OEM Rinnai Component – Genuine manufacturer part designed for compatibility with Rinnai tankless systems
  • Multi-Unit Manifolding – Designed for systems connecting 2 to 5 tankless water heaters
  • Stable Water Temperature – Helps maintain consistent hot water output by balancing system demand
  • Adjustable Activation – Includes an adjustment rod and stopper for fine-tuning activation pressure between units
  • Durable Construction – Manufactured using lead-free brass or copper with stainless steel and plastic components

Compatible Units

  • Rinnai Value Series External Tankless Water Heaters (e.g., V53e)
  • Rinnai multi-unit manifold systems using 2 to 5 heaters
