Water Quality Guidelines

To ensure optimal performance and extend the lifespan of your Echo RO™ system, it is important to monitor your incoming water quality.

Water Hardness

For best results, maintain water hardness levels below:

• 7 grains per gallon (GPG), or
• 120 parts per million (ppm)

Excessive hardness can reduce the efficiency of the RO membrane over time.

💡Tip: Using a water softener before your RO system can significantly extend the life of the RO membrane and improve overall performance.

Total Dissolved Solids (TDS)

Total Dissolved Solids (TDS) is a key indicator of your system’s performance. TDS measures the concentration of dissolved substances in your water, including minerals, salts, and metals.

• A properly functioning RO system will significantly reduce TDS levels.
• Even if your incoming water is hard, the system is working correctly as long as the filtered water TDS remains within an acceptable range.
  ✅ Note: Regularly testing your water’s TDS levels can help you determine when maintenance or filter replacement is needed.

Echo RO Questions & Solutions

Can I connect my RO to the fridge (refrigerator line)?

Yes, you can connect your Reverse Osmosis (RO) system to your refrigerator water line.

The RO line can either:

• Run directly to the refrigerator, or
• Be split using a “T” fitting so it supplies both the refrigerator and the kitchen sink faucet.

If you are installing an H2 Flow system, it can be added to the line going to the sink faucet. The refrigerator line can remain connected directly to the RO system, with the fridge essentially acting as its own dispensing faucet.

Most refrigerator water lines use 1/4" tubing, which is compatible with the RO system connections. In many cases, you can connect directly to the RO system without additional modifications.

If your refrigerator currently uses a copper water line, you may need a simple adapter fitting, which can typically be found at local hardware stores such as The Home Depot, Lowe's, or Ace Hardware.
