24 AugDo You Need A RO Booster Pump?

The purpose of the reverse osmosis booster pump is to increase water pressure going into the RO unit.

 

Reverse osmosis is a pressure-driven process. Small residential RO units will theoretically operate on very low pressure–down to 35 psi, according to some membrane makers–but the reality is, you won’t get a lot of water and the product water quality will be compromised if the unit runs below 45 psi. Low inlet pressure makes the unit produce more reject water, produce less drinking water, fill the storage tank more slowly, and produce lower quality water.

 

RO units run well on typical city water pressure of 60 psi, but they run even better with a small pump to boost the pressure to 80 psi or higher.

 

Do You Need a Booster Pump?

 

Most city water reverse osmosis users have enough city water pressure to run their RO unit nicely and they do not need a booster pump. For example, if your city water pressure is 60 psi or more, there is little to be gained by adding a RO pump. If your pressure is 50 psi or less, however, a pressure boost pump will give your RO unit more zip. You’ll have more water, at a higher pressure, in the storage tank, and the tank will fill faster. The increased pressure will also improve the economy of the unit (it will run less reject water to drain) as well as the quality of the water. RO units thrive on pressure.
