Reverse Osmosis
Do you have the best water possible?
If you’ve ever drank water straight from the tap in Indianapolis, then you already know the water could taste much fresher. Water in Indianapolis and the surrouding areas, whether it's from a municipal source or a well, is high in dissolved solids, affecting the smell and taste. If you want the freshest water possible, then consider a reverse osmosis system today! At All American Aqua, we're proud to offer a catalog of undersink RO systems made in America that provide fresh, delicious water.

What exactly is reverse osmosis?
Reverse osmosis is a mouthful to say, but it's pretty simple to understand once you understand the natural process of osmosis. In nature, when there are two solutions separated by a semi-permeable membrane, the more concentrated solution will migrate to the solution with less concentration. This process is very important in biology since it guides the way water moves about in living things; for instance, it's the reason why there are distinctions between "freshwater" and "saltwater" fish and also how plants maintain their turgor (rigidness).
Reverse osmosis is just the process of osmosis in reverse. However, a key difference is that osmosis is passive, that is, done without external energy. Think of it like a ball rolling down a hill due to gravity. Performing this process in reverse means that highly concentrated water can become pure water on the other side of the membrane, but it will require energy greater than osmotic pressure. In the case of an undersink RO system, this external energy comes from your home's water pressure.
