❓ Frequently Asked Question

Q: Can I install the Echo H2 Machine on the counter but connect it to the waterline under my sink instead of the faucet?

A: Yes, you can! However, if you purchased the above-counter installation setup, you’ll need to purchase an additional fitting to connect directly to the waterline:

• You will need an angle stop T-valve with the following specifications:
  3/8" x 3/8" x 1/4"

⚠ Note: This T-valve is not included in the above-counter setup and must be purchased separately. Echo Water only provides it with the under-counter setup.

🔩Under-Counter Installation

1. Required Equipment

   • 🔗Echo H2 Faucet (vented faucet with three water lines: red, blue, white).
     ⚠ Important: Aftermarket faucets will not pressurize correctly and cause your machine to break, voiding your warranty.

2. Turn Off Water Supply: Shut off the source water before installation.

3. Connect the 1/4" Hose

   • Loosen the nut on the water source valve.

   • Connect the hose to the “T” adapter (Figure 2).

   • Push and fasten the hose into the water inlet at the bottom of the machine (Figure 3).

4. Open Water Supply and Adjust Pressure
   Open the valve and adjust water pressure as needed (Figure 4).

5. Check for Leaks
   Inspect connections immediately and check periodically (at least once a month) under the sink for leaks.

* Check for leaks on the connections part after installation is completed. Periodically check under the sink for leaks about once every month.
