Flow control & restrictors (2020)
What does a flow restrictor do?
A flow limiter, also known as a flow restrictor, is a device that restricts the flow of a fluid, which is often a gas or a liquid in nature. In order to manage both high and low flow rates, some designs use single stage or multi stage orifice plates. Flow restrictor does not reduce pressure.
How to tell if your flow restrictor is bad?
If there is either an excessive amount of water or an insufficient amount of water (or none) going down the drain. If the restrictor becomes clogged and no water drains out, the RO unit becomes constipated, and the water quality deteriorates to the point where it stops producing water entirely.
