FAQs
How do reverse osmosis systems work?
RO systems use a semipermeable membrane to filter water. Under pressure, water passes through the membrane, which allows only water molecules through while blocking contaminants like minerals, bacteria, and chemicals, producing purified water.
How often should you drain an RO system tank?
For RO systems that have storage tanks, we recommend draining them about every two weeks to ensure that the membrane can adequately supply you with clean water.
