Pressure is a key component when it comes to the reverse osmosis system. An RO system requires a higher incoming water pressure for water to pass through the layers of the tiny membrane. The membrane needs incoming water pressure of 50 psi in order for water to pass through. If you have a water pressure of less than 50 psi, you’ll need to look at reverse osmosis systems that include a booster pump or purchase a booster pump to increase water pressure.

Check your incoming water pressure using the water pressure gauge.
The importance of a booster pump for your reverse osmosis system
If your incoming water pressure is less than 50 psi, the system will produce low-quality water and reject more water into the drainage, leading to high water bills.
To reduce water wastage, you need to install a booster pump to increase pressure. Also, the increased pressure will help the system work efficiently, thus providing quality water and allowing the tank to fill faster.
The pump adds pressure needed to perform treatment functions and helps move treated water from the storage tank to the point of use, such as the faucet.
Different types of reverse osmosis system pumps
There are two types of pumps used in the reverse osmosis system.
- Booster pump-raise water pressure as it enters the RO unit
- Delivery or demand pump – move filtered water from the storage tank to the appliance such as faucet, refrigerator, and icemaker.
The booster pump is available in two types: an electric pump and a permeate pump.
Difference between the electric pump and a permeate pump
The electric pump requires electricity to operate while permeate pump uses water pressure to increase the pressure needed.
The permeate pump not only saves energy but also reduces the amount of water required to flush the membrane. For instance, instead of using four gallons to produce one gallon of water, the RO system using a permeate pump wastes one gallon to produce one gallon of filtered water. You need two gallons of contaminated water to produce one gallon of pure water.
How does the permeate pump work?
