What is a reverse osmosis system?
A reverse osmosis (RO) system is an under-sink filter that pushes water through a semi-permeable membrane and gives you a dedicated tap for purified drinking water. Done-Rite Plumbing & Rooter installs RO systems in Orange County homes.
Drinking water that tastes metallic, smells faintly of chlorine, or keeps you buying bottled water because you don't trust the faucet is a sign your home could use a real upgrade in water quality. Done-Rite Plumbing & Rooter is ready to install a reverse osmosis system for clean, great-tasting water and peace of mind.
How do I know if reverse osmosis could help my home?
The four main signs reverse osmosis could help are water that tastes or smells off, cloudy water or ice, countertop appliances clogged with scale, and simply wanting an extra layer of protection for drinking water.
Why does my tap water taste or smell off?
Off tastes and odors in tap water, such as chlorine, metallic, earthy or rotten-egg notes, usually come from dissolved solids, chlorine, chloramines, sulfur compounds or organic matter.
Beyond the unpleasant experience, those tastes and smells can point to substances that are often safe at low levels but still worth removing from the water you drink every day.
Why is my water or ice cloudy?
Cloudy or milky water, or ice cubes that come out opaque or with white flecks, often points to a higher level of total dissolved solids (TDS), which is exactly what a reverse osmosis system is designed to reduce.
Cloudiness is often just cosmetic, but a high mineral content can change the taste of drinks and food.
Why do my kettle and coffee maker keep scaling up?
The white, crusty buildup inside a kettle, coffee maker or humidifier is mineral scale left behind when water with a high mineral content is heated or evaporates.
Scale clogs small passages, insulates heating elements and shortens the life of countertop appliances. Feeding those appliances RO water removes most of the minerals before they can build up.
Is reverse osmosis worth it just for better drinking water?
Many households choose reverse osmosis as an extra layer of protection for the water they drink, whether for a newborn, a family member with a health condition, or general peace of mind.
Reverse osmosis is one of the most thorough point-of-use filtration methods available. The RO membrane blocks a wide range of dissolved contaminants, including many metals, salts and chemicals.
What does a reverse osmosis system remove?
A reverse osmosis system reduces total dissolved solids, removes chlorine and chloramines with its carbon pre-filters, and filters out a broad range of trace contaminants that other filters can miss.
What are total dissolved solids (TDS)?
Total dissolved solids (TDS) are the total amount of minerals, salts and metals dissolved in water. Water picks them up as it moves through soil and rock and travels through pipes.
A high TDS level gives water a flat, salty or mineral taste and leaves spots on glassware. A reverse osmosis system pushes water through a semi-permeable membrane that separates out most of those dissolved solids and flushes them away, leaving highly purified water behind.
Does reverse osmosis remove chlorine?
Yes. An RO system includes activated carbon pre-filters that are very effective at removing chlorine, chloramines and many organic chemicals, which improves both the taste and the quality of drinking water.
Water utilities add chlorine or chloramine to keep water safe from bacteria on its way to your home. Those chemicals are important for safety, but they leave a distinct taste and odor, and they can react with organic matter in the water to form disinfection byproducts.
Can reverse osmosis filter trace contaminants?
Yes. The multi-stage filtration of a reverse osmosis system, and especially its semi-permeable membrane, is very effective at removing a broad range of trace contaminants.
Modern testing keeps finding trace contaminants in water supplies that older filtration methods aren't always built to handle, including pharmaceuticals, pesticides, herbicides and certain industrial chemicals.
How does Done-Rite install a reverse osmosis system?
Done-Rite installs a reverse osmosis system in five steps: choose the location, assemble the unit, connect it to the cold water line, add a dedicated faucet and drain connection, then flush and test it.
- Plan the location: Our technician reviews your needs and discusses the best location for the RO system, usually under the kitchen sink. We check your existing plumbing to confirm compatibility and find the cleanest, least intrusive way to connect.
- Assemble the unit: The RO unit usually includes several pre-filters, the RO membrane, a post-filter for final polishing and a storage tank.
- Connect the supply: We tap into the cold water supply line and connect the system carefully so every connection is leak-free and water flows properly.
- Add the faucet and drain: We install a dedicated faucet for your purified water, which often means drilling a new hole in the sink or countertop. We do that with care and only with your OK. We then connect the system to the drain line so the rejected contaminants can flush away.
- Flush and test: We flush the system to clear any manufacturing residue and trapped air, check every connection for leaks, and perform a water quality test to confirm the RO unit is working properly.
Before we leave, the technician walks you through how the system works, explains the filter replacement schedule and answers your questions.
Which other water treatment services does Done-Rite offer?
Done-Rite also installs water softeners for hard water and whole-home filtration for water at every tap. Our comparison of softeners, filtration and reverse osmosis lays out the differences.
For problems tied mainly to hard water and the damage it does to plumbing and appliances, we handle Water Softener Installation. If you want protection beyond drinking water, Whole-Home Water Filtration systems address sediment, chlorine and other contaminants at every tap in the house.

Water Treatment questions
A softener handles hardness and scale for the whole house. Whole-home filtration handles sediment, chlorine and taste at the main. Reverse osmosis polishes drinking water at one tap. Many homes end up with a softener plus RO at the kitchen sink.
We offer water testing, and we'll recommend equipment based on the result. Sometimes the answer is that you don't need anything.
