Reverse osmosis, or RO, is a way to filter drinking water at one tap, usually under the kitchen sink. Water is pushed through a very fine membrane, and most dissolved material stays behind and goes down the drain. What reaches your glass tastes cleaner to many people.

Why Cape Coral homeowners ask for RO

Southwest Florida water tastes different from what many people are used to. Some dislike the taste of treated water. Others live on wells. People want clean water for drinking, coffee, ice and cooking, without filtering every tap in the house. That is what an under sink RO system is for.

What a typical system includes

Pre filters that protect the membrane from sediment and chlorine
The RO membrane itself
A small storage tank, so water is ready when you open the tap
A post filter for final taste
A separate faucet on the sink, and a drain connection

What to look for

Look for NSF/ANSI certification on the system. The standards that apply to RO and drinking water treatment are independent, and the product listing shows which claims were tested. Do not accept vague promises. Ask to see the certification for the exact model being installed. We do not make health claims, and neither should an installer.

Things to know before you buy

RO systems send some water to the drain as they work. Ask how much. The filters and membrane need replacing on a schedule, so ask for the yearly cost. The system needs space under the sink and sometimes a hole for the faucet in the countertop, which is worth knowing before the install day.

Hard water and RO

Hard water can shorten the life of an RO membrane. If your water is very hard, a softener upstream often helps protect it. On a well, treat iron and sulfur first. See well water treatment.

Plumbing and permits

An under sink unit connects to the cold supply and the drain. Many are simple, but work that taps the main line, or a whole house RO, usually involves a licensed plumber and may need a permit.

To compare what is in your supply, use your utility's annual water quality report, or a lab test for a well. Ask for a written flat quote. See also water testing.
