All of the attributes of UltraStream water can be controlled by flow rate. The faster the water flows through, the less pH and hydrogen potent it is. We recommend a flow rate around 1.0 L/min for the best performance. If you want a lower pH, simply increase the flow rate.


The UltraStream has a unique ‘twist n flow’ control to regulate flow rate, meaning you have no need to adjust the faucet’s flow rate. Just turn on the tap to full and the UltraStream regulates the flow. Be careful to not completely shut-off UltraStream by twisting the base to “off.”
