WECO Economy RO/DI Pressure Booster Pump Kit

Well water supplies often suffer from low or inconsistent water pressure. Well pumps may not be able to maintain the proper water pressure (60+ PSI) required 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 30 PSI, the RO system will divert more water to drain than is necessary. The water purity of the filtered water can also decline because the reverse osmosis membrane cannot function properly.

The WECO Booster Pump kit can be used to correct a low-pressure condition or replace a broken booster pump. The booster pump retrofit kit is a direct fit replacement for all undersink reverse osmosis filter systems. The WECO Booster Pump uses a safe low-voltage transformer to provide electric power to the pump. The booster pump increases the incoming water pressure to the ideal 60 PSI. This water pressure level maximizes the number of gallons produced per day while minimizing the amount of wastewater sent to the drain.
