What is the minimum flow rate for checking the RO faucet, as per the standards?

The minimum flow rate for checking the reverse osmosis (RO) faucet is set at 0.5 gallons per minute (GPM). This standard is established to ensure that the RO system is operating efficiently and effectively, as a flow rate that is too low may indicate issues such as membrane fouling or other operational problems.

A flow rate of 0.5 GPM is generally considered sufficient for assessing the performance of the filtration system while also providing an adequate supply of filtered water for typical household use. This rate balances efficiency and practicality, ensuring that the user does not experience delays or insufficient water supply while utilizing the RO system. Monitoring this flow rate is crucial in maintaining the performance and longevity of the RO system, as deviations may suggest a need for maintenance or adjustments.
