North Brothers Plumbing‘s reverse osmosis water treatment uses changes in pressure to filter out chemicals and contaminants from your water supply. Over the years, this method has become much more advanced than before, and modern treatment solutions deliver the highest quality water to your home or business for years with relatively little maintenance.

As pressure is applied to your water in the reverse osmosis water treatment system, it is pressed through a semi-permeable membrane that filters out hard water, bacteria, and anything that causes pH imbalance. As a result, you get:

Water that’s clear and looks amazing
Freshwater that tastes great
Water that’s free from any foul odor
Long-term sustainability for your pipes and fixtures

Water treatment technology has made treatment easier than ever, and North Brothers Plumbing has a large supply of different tank sizes and treatment system components to make your water treatment more efficient, all while maintaining the right water pressure.

Most importantly, you’ll have your local water professional helping you get the high-quality water your family deserves and the service to back it up for years to come.

You’ll Have Options:

We can typically connect to your fridge for delicious cold water and crystal clear ice cubes
Unique and elegant chrome or brushed nickel faucet styles.
Optional electronic faucet indicates when filters and membranes need to be replaced.
The system is expandable if additional filters need to be added.
Additional filter selections are available, including higher capacity sediment, or a Volatile Organic Compound (VOC) rated filter.
The membrane can be upgraded to a 75-gallon per day membrane.
Adaptor kits are available to easily add a permeate pump system, which provides improved flow rates at the faucet.
