ED - Extra Duty Reverse Osmosis Unit

This Energy Recovery Reverse Osmosis System will add the pressure you will need for the new refrigerator, which require higher pressure. This permeate pump is also perfect for reducing your waste water.

*Upgrading to a Catalytic Carbon stage removes on average five times more Chloramines than any carbon block on the market (including the ones specifically designed to "bust" chloramines). The option above adds Catalytic Carbon cartridge in place of 5 micron carbon block.

Extra Duty RO Unit Features:

The Extra Duty Reverse Osmosis Unit comes complete with everything you need to install and use. Installation is easy; the plumbing connections are plug-and-play. No pipe dope, Teflon Tape, wrenches, or glue. These fittings just push in. The typical RO system stores water at around 30 psi the ED drives that pressure to 45 PSI.

More than enough water pressure. The ED Reverse Osmosis System does this while saving you up to 80% of the water wasted by normal tap water systems. Simple to install no bigger than an ordinary system, the Permeate Pump does make a clicking noise every few seconds, forcing the pure water into the storage tank. (If the noise is too loud for you can wrap a dish towel around the unit to make it a quieter pulsating sound.) You will love it!

This permeate pump will increase the quality and quantity of water and was designed specifically for those with cold, low-pressure, or poor water quality. The Permeate pump is the Auto Shut off Valve. The ERP 500 is a quiet Permeate Pump designed for household usage with RO drinking water systems. Our ED (Extra Duty) unit is a five stage, permeate pump enhanced, RO drinking water system.
