An Advanced Water Solutions Reverse Osmosis System provides you with high-quality water for worry-free drinking and cooking. These state-of-art filters will improve the quality of water from wells or municipal water supplies. WITH THE EQUIVALENT OVER 10 CASES OF BOTTLED WATER AT YOUR FINGER TIPS EVERY DAY, YOU’LL USE YOUR HEALTHY DRINKING WATER FOR JUST ABOUT EVERYTHING…

  • Your drinking water will taste as good as the best bottled water on the market right out of your tap.
  • Your ice cubes will be crystal clear. (The cloudiness in ice cubes is caused by the solids in your water)
  • Coffees, teas, and mixed drinks will taste better.
  • You can use great water for rinsing fruits and vegetables.
  • Your pets will even get so used to the water they may refuse to drink tap water again. It happens!


  1. Sediment prefilter to remove dirt, sand, and silt.
  2. Carbon Block filter to remove chlorine taste and odor.
  3. High-volume, semi-permeable membrane that rejects up to 98% of most dissolved solids in your water.
  4. Automatic shut-off control to balance production of filtered water with your needs.
  5. We offer affordable purchase and rent-to-own options that fit your budget!

How do I turn off the RO system if it is leaking?

  • There are two shut off valves. One is near the cold water line going up to your hot and cold kitchen faucet. It is on the line feeding the RO system. The second one is located on top of the metal tank. Turn both handles ¼ turn to shut off the water. You can only turn the handle one way. The handle will be perpendicular to the body of the valve when it is shut off. When the handle is parallel to the tubing, it’s open.

Why is there a dark tint to my water?

  • The first time you use your new reverse osmosis system or after the filters have been changed, the water may have a dark tint to it.  Do not worry this is normal.  The carbon filter is brand new and just needs to be flushed a little more. Open the reverse osmosis faucet and allow all the water to run out.  This will empty the tank and flush out the carbon filter.

My water is white or cloudy. How can I clear it up?

  • There are several reasons this may have occurred. Fill a glass of water and allow it to sit for a few minutes. Does the color disappear? If yes, then it is air bubbles in the line of the new system. Don’t worry; this will stop once all of the air is out of the lines.  Open your new reverse osmosis faucet and allow all the water to run out. This will empty the tank and should remove all the excess air from the system. If no, it is most likely caused by a coral calcium mineralizer.  Open your new reverse osmosis faucet and allow all the water to run out.  You may have to do this more than once to flush the excess from the mineralizer.

Why do I hear a clicking or hissing noise coming from my system? 

  • This noise is normal and is caused by the little black pump on the system. This pump makes your RO system more efficient by minimizing the amount of water going to the drain. The noise will stop once the tank is full of drinking water. It could take several hours.

Why is there no water coming from the RO faucet?

This can happen for many reasons.

  • The storage tank may be empty and simply needs time to refill.
  • After several hours the storage tank is not full, the system probably needs servicing.
  • The pre-filter may be clogged and needs replacing.
  • Leak detector may have been tripped and the water coming into the
  • RO has been turned off. Remove the sponge and put the lever down.
  • Check for leaks in two (2) hours and call us if the RO is leaking.

How often do I need to replace the filters in my system?

This depends on the feed water quality. The chart below is the average schedule.

Description Interval
5 Micron Sediment Pre-Filter 6-12 months
Carbon Block Pre-Filter 6-12 months
TFC Membrane 24-48 months or when expended
Inline Post-Carbon Filter 6-12 months
Ultra Violet Light 12 months
Coral Calcium Mineralizer Filter 6-12 months

To insure you are getting the same water quality as when your system was new, it requires periodic maintenance. The most important of which is the timely filter changes. Failure to change filters may reduce membrane life and water quality dramatically.

  • Did you know? Advanced Water Solutions, Inc. recommends changing your reverse osmosis filters every 12 months. Even if the system is not used on a regular basis.
  • Reason: It is not just the usage level that causes the need to be changed, but time the filters spend in the system. Leaving the filters in place can increase the possibility of bacteria growth on the filters.

I have used Advanced Water Solutions and their Reverse Osmosis equipment in my home for over two decades. The owner, Jay, has always been great to work with, and his staff are skilled, professional, and easy to talk with. Tim recently performed the annual service on my equipment, and like Alanzo, he knows what he is doing and is happy to explain it all to me. One of the great things about their equipment is that it is a huge water saver because it uses a lot less to make the RO water than other equipment available. I have referred Advanced to family and friends all over the Santa Barbara and Ventura areas and like me, they stay with Jay and Advanced for years.

I must say, I am very happy with my new water system. Advanced Water Solutions has been a wonderful experience. From the sales, by Paul and the installation by Timothy. Both of them were extremely nice and personable. Also, there is Paulette in the office that was very helpful to any question(s) I have had and feel comfortable calling with any in the future. So keep up the great job! I will recommend this company to friends and family.

When I read our municipal water company’s disclosure about the chemicals added to ensure our city water is safe, I was concerned about the monochloramine (which is a combination of chlorine and ammonia). My husband was on board with filtering our water and trusted Advanced Water Solutions because he knew some their satisfied customers. We chose an AWS125 water softener with a whole-house carbon filter. Alonso did our installation and he was terrific. His work was impeccable and he clearly explained what he was doing and how the system worked. After the installation, Alonso tested the water, which we watched, explained the results and patiently answering our questions. We are thoroughly satisfied with the complete filtration system.

Tim came out to fix our water softener within hours of me calling and fixed the problem, quickly and efficiently! We ended up upgrading to a new water osmosis/carbon filter! Tim is so knowledgeable, kind, easy to talk to and I truly felt he cares in making sure we have clean water to drink! I am so glad we switched to Advanced Water Solutions for our drinking water and look forward to having cleaner, better tasting water... on top of the water softener that Tim rushed out to make sure was working properly. I feel confident in this company and I hope Tim's boss realizes they have a Gem of an employee, that represents you guys SO well!

Advanced Water Solutions has helped us with two commercial installations. Jay and his team are always professional and always get me the best prices. The system is fantastic as is the service! The few times I have had issues, a techninian was on site immediately. If you are looking for a company that does what they say they will do - then Advanced Water Solutions is for you.

My long serving and rare Braswell Water Softener failed over the weekend. All the available water was salty with a capital T. Called this am first thing. They sent Danny out this afternoon. He was here 10 minutes checked a couple of possible causes. Very professional and knowledgeable. Had it nailed in short order. He explained thoroughly, had the necessary parts in the truck and was outta' here in 30 minutes. Very reasonable charges and I'm back in business. The way things are supposed to work but rarely does. Thank you Danny you're an ace! Thank you AWS. Well done all!
