Our flow restrictor is made of food grade material, which allows users to connect and disconnect quickly without the need of any other tools.
It is used to give you the most RO water for the least amount of waste water production.
It's purpose is to create back pressure on the drain line to help push water through the membrane but flow fast enough to keep it clean.
