Meet the Echo Flow™

The Echo Flow® delivers powerful hydrogen-enriched water in a sleek, space-saving under-sink design. Producing up to 1.2 liters per minute, it supplies fresh hydrogen water on demand for the whole family.

Installed directly under your sink, the Echo Flow connects to your kitchen faucet, refrigerator line, or existing filtration system. Powered by the proprietary Echo Hydrogen Module™, it infuses clean water with up to 1.21 ppm of molecular hydrogen—without changing the water’s natural pH.

The result is clean, refreshing hydrogen-enriched water designed to support everyday hydration and wellness.

Echo Flow™ Installation Guide

Follow the steps below to properly connect your Echo H2® Server to your existing filtration or reverse osmosis system. .

A pre-filter must be installed before the Echo Flow, as it does not include built-in filtration.

Installation & Faucet Requirements

  • Secondary Faucet Required: The Echo RO/Server Faucet™ dispenses hydrogen water separately from your main faucet.

  • Countertop Hole: Requires a 15/16”–1” hole (often available from soap dispensers or accessories). Professional drilling is a low-cost option if needed.

  • Electrical Outlet: A dedicated outlet is required to ensure consistent power supply for the under-sink unit.

Before You Begin

  • Turn off the water supply to your filtration or RO system.

  • Confirm that all tubing used is 1/4 inch (0.635 cm) diameter.

Step 1: Connect the Incoming Water Line

Locate the tube that currently runs from your filter or RO system to your faucet.

  1. Disconnect this tube from the faucet.

  2. Insert this tube into the IN port on the Echo H2® Server.

This line now carries filtered water into the Server system.

Step 2: Connect the Outgoing Water Line

  1. Take the new 1/4" tube included with the Echo H2® Server.

  2. Insert one end into the OUT port on the Server.

  3. Connect the other end to the faucet connection.

This line carries hydrogen-enriched water from the Server to your faucet.

Step 3: Restore Water Supply

Turn the water supply valve back on to your filtration or RO system.

Step 4: Connect Power

  1. Insert the DC12V 8.3A power adapter into the power port on the Echo H2® Server.

  2. Plug the adapter into a surge protector.

  3. Confirm the green LED indicator on the power supply is illuminated.

Step 5: Test the System

Turn the faucet on and off several times to allow water to move through the system and ensure the Echo H2® Server is operating correctly.
