How do RO flow restrictors work?
RO flow restrictors help maintain a reverse osmosis system by limiting the amount of wastewater the system produces. The flow restrictor is connected to the outlet tubing of the RO membrane, where it prevents pressure inside the membrane from dropping too low. Without a flow restrictor, the pressure in the RO membrane will drop too low, and the system will not function properly.
Additionally, the flow restrictor helps prevent the RO system from producing excess wastewater. If the water is allowed to flow through the system to the reject outlet unrestricted, this creates greater volumes of wastewater and drops the pressure applied to the membrane. Other factors, such as low incoming water pressure, can impact the operation of an RO system.
If this is the case for you, a reverse osmosis booster pump will solve your problem. In other cases, the flow restrictor may need to be replaced.
Where does an RO flow restrictor go?
Flow restrictors in an RO system insert into the connection between the RO membrane and the drain tubing, also known as the waste pipe. Most RO systems come with a flow restrictor because they are needed to operate smoothly. A flow restrictor should be replaced when you replace your RO membrane, about once every year. This prevents scale buildup from wreaking havoc on your restrictor and, consequently, your RO system.
