Can you use any faucet for reverse osmosis?

If you have enough clearance from the RO faucet, you can use it for the water flow.

The soap dispenser or spray hose can also be used for the RO faucet.

The RO faucet requires a hole size on the sink (or countertop) that is at least 7/16”

Can I use my own faucet with a reverse osmosis system?

To create enough pressure for the shower head, it’s physically connected to the kitchen faucet. But, when the water in the storage tank is low, and the tank is empty, you’ll have only the RO system’s production rate – which is a trickle (2-4 gallons per hour).

Does reverse osmosis require a special faucet?

Many plumbing codes require the use of air gap faucets with reverse osmosis (RO) units.

We offer standard model faucets. We also supply air gap models if requested, but do not guarantee them.

Are reverse osmosis faucets universal?

Universal fit of non-airgap reverse osmosis filter faucets with 1/4″ feed line.

This product is for all water lines that have a diameter of at least 2/16″.

Provides a 3/8” quick-connect for easy, fast, leak-proof installation.

Why does reverse osmosis faucet leak?

Most often a water leak is caused by: A plug or restriction on the drain side of the faucet air gap (3/8″ tubing). Incorrect connection to the drain.

Is an air gap faucet necessary?

Most plumbing codes require an air gap on the RO drain line to avoid possible contamination.

The RoR system has to dispense water through its own faucet so it can be a fully-integrated system with a built-in air gap.

Is Brass compatible with RO water?

Copper can easily leach into your RO water, diminishing its purity.

Brass is not as easily corroded as copper by RO water, but it still should be avoided for this application.

Can you Remineralize reverse osmosis water?

You can quickly remineralize any quantity of water just by adding a few mineral drops anytime.

Mineral water bottles should treat up to 200 gallons of water and cost less than $20 to buy.

Remineralizing reverse osmosis water can be done at source if you add in an extra filter to your system.
