Reverse osmosis filtration systems work on the principle of forcing water through
a spiral-wound semi-permeable membrane. Reverse osmosis filtered water is often
called fresh squeezed because it is literally squeezed through the RO membrane.
Salts, like sodium, chloride, and potassium along with nitrate, sulfate, lead and
other contaminants cant pass through the membrane and get flushed or rejected
down the drain as waste water, while purified water is collected in the water
storage tank. Many water supplies suffer from low or inconsistent water pressure.
Well, pumps may not be able to maintain the proper water pressure for an RO
filtration system. Even some municipal water systems have unsuitable water
pressure. If you live in an apartment or high-rise building your water pressure can
fluctuate as water use increases throughout the facility. This may cause your
reverse osmosis filter system to stop working or work very poorly. If the water
pressure is below 45 PSI, the RO system will send more water to waste than is
necessary. The water purity of the filtered water can also decline because the
reverse osmosis membrane cannot function properly.

The APEX 150 Booster Pump can be used to correct a low-pressure condition
or replace a broken booster pump. The APEX 150 booster pump is a direct fit
replacement for APEX reverse osmosis filters. The APEX 150 Booster Pump
uses a safe 24-volt low-voltage transformer to provide electric power the pump.
The booster pump increases the incoming water pressure to the ideal 80 PSI.
This water pressure level maximizes the number of gallons produced per day
while minimizing the amount of wastewater sent to the drain. The APEX 150
Booster Pump is designed in the United States and manufactured with high-quality
components that will provide years of trouble-free service.

The booster pump installation can be performed as a DIY project. We advise
installation by a licensed plumber to ensure adherence to all local codes.
