Is the water really as good as bottled?
Yes – The system uses multiple processes including Reverse Osmosis to make great tasting, low sodium drinking water. Reverse Osmosis removes about 97% of the TDS (Total Dissolved Solids) including salt and sodium from the water. Read the labels on bottled water and you will discover Reverse Osmosis is the same process used by most bottlers. In effect, you really are getting "bottled water without the bottle".
What is Reverse Osmosis?
Reverse osmosis (RO), also known as "hyperfiltration", is the process which removes a majority of the dissolved impurities found in some tap water. Reverse osmosis systems provide filtered water everywhere, from homes and commercial applications like restaurants and hotels, to breweries and car washes, and even the space shuttle!
Can I hook the service up to my refrigerator ice maker?
Yes – in most case we can connect directly to your refrigerator. Connecting the system will extend the life of your ice maker and make great tasting ice. Turn your fridge into a Culligan water & ice machine.
Does the system require any maintenance or service?
Yes – we take care of all service and maintenance 24 hours a day, 7 days a week. Every 18 months, our certified technicians will come to your home for a TSR (Total System Replacement) absolutely FREE! It's like getting a brand new Home Drinking Water System every time! Call us or fill out the form on this page and let the Culligan Man do all the work for you.

Filtration Stages
STAGE 1:
Raw tap water initially flows through a 1.0 micron filter that is 4 times larger than conventional filters. This removes dirt, rust and other solid objects.
STAGE 2:
The water then flows into an industrial grade carbon filter that takes out 98% of the chlorine and most organic chemicals.
STAGE 3:
A composite reverse osmosis membrane next removes up to 99% of the dissolved contaminants from the water molecules, which are all rinsed down the drain.
STAGE 4:
The fresh, clean water is stored in a reservoir tank located under the kitchen sink, where it will be disbursed through a designer sink faucet and/or to the refrigerator for ice or water.
STAGE 5:
Finally, the water is filtered with a "polishing filter" before it reaches your glass. This insures that your fresh, clean Culligan water tastes good.
How does a Reverse Osmosis System know when to produce water?
A standard RO System has a hydraulic on/off pressure valve which is controlled by source water pressure to send pre-filtered water to the membrane to make water for storage.
When water pressure in the storage tank builds up to 90% of the incoming line pressure, the standard hydraulic on/off pressure valve shuts off the flow of water to the system, stopping treated water production. When you open the RO faucet, system pressure drops as treated water exits the tank. The standard hydraulic on/off pressure valve turns on when the tank pressure is less than the source water pressure and treated water is produced through the RO system. The cycle repeats itself.
