Why should I call a professional reverse osmosis installer?

Expert installation helps ensure the system is correctly sized, properly connected, and accurately configured for your home’s plumbing and water quality. It also helps maximize system performance and reliability.

How do I know when I need a reverse osmosis water filter replacement?

Common signs include slower water flow, less production, and changes in taste or odor. Another sign is that you have gone over the manufacturer’s recommended replacement schedule.

How often do RO filters need to be replaced?

Most pre-filters and carbon filters should be replaced every 6 to 12 months, depending on water quality and daily usage.

How often should I replace the reverse osmosis membrane in my whole-home filter?

Most RO membranes last about 2 to 5 years. The lifespan depends on system maintenance frequency, water quality, and daily water usage.

What do carbon filters in RO systems remove from household water?

Carbon filters help reduce chlorine, chloramine, unpleasant tastes and odors, and many organic compounds. They also help protect the RO membrane from damage.

Can an RO system be installed on well water?

Yes. Reverse osmosis systems work well for many private wells. In some cases, pre-treatment may be recommended to address iron, manganese, sediment, or bacteria before the water reaches the RO system.

What should I do if my reverse osmosis system stops producing water?

Make sure the water supply valve is open, then check for clogged filters, low water pressure, or a full storage tank. If the issue continues, contact Carroll Water to inspect the system.

Can RO water be connected to my refrigerator?

Yes. Many reverse osmosis systems can supply purified water to your refrigerator for cleaner ice and drinking water.

Does reverse osmosis remove PFAS?

Properly maintained reverse osmosis systems can reduce many PFAS compounds. They are one of the most effective residential treatment options for these contaminants.

During a boil notice, do I still need to boil water if I have RO?

Yes. During a boil water notice, follow your local water utility’s guidance. Reverse osmosis systems are not designed to replace boil water advisories unless specifically approved by local health authorities.

Will installing RO require drilling my countertop?

Usually not. If your sink already has an unused accessory hole, it can often be used for the RO faucet. If no opening is available, a small hole may need to be drilled in the countertop or sink.

What is the difference between a reverse osmosis (RO) system and a whole-house filtration system?

A whole-house water filtration system purifies all water flowing into your home. A reverse osmosis system typically provides highly purified drinking water at a specific faucet. Many homeowners install both systems or invest in a whole-home RO system.

What Is Reverse Osmosis (RO)?

Reverse osmosis (RO) is a water filtering process that removes almost all dissolved contaminants from your water. The system pushes water through a special membrane with tiny holes that lets water molecules pass through but blocks numerous contaminants, like metals, chemicals, and minerals. The result is exceptionally clean water that tastes great and is free from harmful substances.

How Does a Whole-House Reverse Osmosis System Work?

When you need whole-home water filtration, you can depend on our team. From advanced RO systems to water softeners and UV water treatment, we provide customers with a variety of advanced filtration options.

Reverse osmosis water filtration systems clean your water through several steps:

Pre-Filtration: Water first passes through pre-filters that remove large particles, like sediment. This protects the main membrane and helps the system work better.
Reverse Osmosis Membrane: The heart of your system is the RO membrane. Water is pushed under high pressure through this semi-permeable membrane. The membrane allows only water molecules to pass through, effectively removing dissolved salts, heavy metals, fluoride, nitrates, and more.
Post-Filtration (Polishing): After passing through the membrane, water goes through a final carbon filter that removes any remaining tastes or odors.
Storage Tank: Clean water is stored in a pressurized tank until you need it. This ensures you always have filtered water ready when you turn on the tap.

What Does Reverse Osmosis Remove From Water?

Reverse osmosis water filters typically remove 95–99% of most dissolved solids, including particles as small as 0.001 microns.

RO can help reduce and remove the following contaminants from water:

Lead and other heavy metals
Arsenic
Fluoride
Chlorine
Dissolved minerals that affect taste
PFAS
Nitrates
Tannins

Bad Taste and Odor

If your water tastes metallic, smells like chlorine, or has other unpleasant tastes or odors, an RO system can help address these problems.

Hard Water Issues

While primarily a purification system, reverse osmosis also removes the minerals that cause hard water. Therefore, RO helps reduce scale buildup, staining throughout your home, and improves the taste of your water.

Cloudy or Discolored Water

RO systems clear up cloudy, yellow, or brown water by removing particles and dissolved substances that cause discoloration.
