Our exclusive line of reverse osmosis water purifier systems are specifically designed to provide clean, clear, better-tasting drinking water by removing more than 95% of dissolved solids including many harmful contaminants. Now you can have bottle-quality water at your tap.

With an WaterCare Reverse Osmosis System You Get:

  • Semi-permeable membranes to reject solids
  • Three or four-stage water filtration
  • Specially formulated pre-and post-filters to reduce contaminants, eliminate odors, and improve taste.
  • Automatic shut-off to conserve water
  • Optional electronic monitor to alert you when filters need changing
  • Space-saving designs

Here’s How Reverse Osmosis Works:

  1. Household water is directed through a pre-filter for filtration to remove sediment, chlorine taste and odor, and particulate matter.
  2. The water is then forced, by pressure, through a semi-permeable membrane where a high percentage of the dissolved solids and other contaminants are rejected and flushed to the drain.
  3. Final polishing of the water is accomplished by an activated carbon absorption block filter removing tastes and odors. The water passes through this final filtering process immediately before going to the faucet whether it comes directly from the unit or from the storage tank.
  4. The automatic shut-off control shuts down the system when the storage tank is filled and water is not being drawn. This “demand production” feature conserves water by eliminating the constant running to the drain found in some units. The control also depressurizes the membrane when not in service extending the membrane life and reducing the need for maintenance of your reverse osmosis water purifier.

Certain Services, Inc. offers a broad range of reverse osmosis purification systems. These products reduce substances such as chlorine taste, sediment, nitrates, lead, cysts, and detergents.

I cannot say enough about the entire team from Certain Services. Moving into a new home only to find out you have salt water coming from your pipes can be an extremely frustrating realization. But everyone at certain services, from the always friendly receptionists, to the knowledgeable techs who are ready to teach you about every option, made the process much less painful. We shopped around for our whole home reverse osmosis system, but the service and care taken by the entire team is second to none. If you have any water troubles I couldn’t recommend them more. We finally have the freshest water coming into our home, and we cannot thank everyone at Certain Services enough for helping us along the way.

This is our go-to water treatment company. Most recently, we had the dreaded sulfur smell in our water and I found that our sulfur block was leaking. Two technicians were able to come that same afternoon, and they had us back on track quickly by replacing a piece that had gotten clogged and sanitizing the whole system. The water is back to smelling like nothing ever happened, and the bill was fair for a couple hours of work. We will be using them again if and when we need service on our equipment.

I have used Certain Services twice and l am totally pleased. Nick came this time to help since my water system wouldn't backflush. Nick came and said l needed a new system card. He installed the card and everything worked perfect. He explained the problem and what he did to correct it. I am very happy with Certain Services and will call them again when I have water problems. Thank you .

The technician was efficient and thorough. He was polite. I was very impressed at how quickly he completed the job. He also cleaned up after himself. Left the area better than he found it.

I was extremely pleased with the Certain Services technician and his approach and knowledge. He took the time to explain to me how the water treatment system operated and what needed to be done as regular maintenance. It is never a good experience to learn you are in need of a major component replacement, but the technician fully explained our options and the impact of our non-functioning water softener.We will be making a decision very soon on replacing the water softener and based upon our initial exposure, it will Certain Services who does the work.

Class act company! So glad that we took the time to investigate a few companies and RO Systems. That being said Certain is definitely the #1 choice. From the 1st day when calling the office (Kellie) answered the phone set an appointment and kept the appointment showed up on time!Bill (Owner) came out tested our water and sat down and explained the findings and what was the only choice obviously with such high TDS also broke everything down so WE could understand exactly what we were getting. (Other companies just throw prices at you) He showed us the products and what it would look like outside also. (NO PRESSURE) You have a choice to maintain the system on your own or sign up for the monthly warranty & service program. Which for us was a no brainer to have them do it & very reasonable monthly price. (For what we are saving to eliminate bottle water alone covers the cost)After deciding YES we are going with this system, it was a little after 5pm (Kellie) answered again put us on the schedule right away told us guys will be here at 8:30am and that they were! Ready to work! Had the entire system up and making water by 5:30pm DONE! Gave me instructions on flushing the inside the next day and said 3 days you will have perfect water. Well yes we have perfect water AT EVERY FAUCET!!!I was outside saw a small leak coming from a pipe called office AGAIN (Kellie) answered my call said no problem ! Today showed up to fix it!!So if you are looking for PERFECT WATER definitely give CERTAIN SERVICES A CALL you will not be disappointed!

We have used Certain Services since moving to North Port 5 1/2 years ago. The company is very reliable and technician are courteous and knowledgeable. We recently found ourselves without water due to pressure valve. They were very prompt responding and had us up and running. I would highly recommend Certain Services for all of your water and pluming needs.

I have had several companies come out to service my well over the years and every one has recommended expensive repairs/upgrades that were unnecessary. The technician from Certain services was willing to spend time to educate me on how to maintain the equipment I have. Some of it is very old but he did not try to push expensive replacement, he was very honest and did an amazing job! I will be using and recommending Certain for all my well and plumbing needs!

Joe was the hero of the day for me. He was pleasant, professional, helpful, friendly, and he got everything done very quickly. I asked him for his card in case I have an issue somewhere down the road. I would recommend your service and say a 5 star rating.

Very professional company and their people are amazing. I would recommend them to anyone who needs service for their water system. In this extreme heat Cody the tech did not try to take shortcuts, he stood out there completing everything that needed to be done. Kelly who answered the phone explained in detail what was needed to be done and answered all my questions extremely professionally. Great Company.

Certain did a good, and fast job installing our new water softener. Hopefully it will continue working for years to come. I would give it 5 stars, but I’ve only had it a few days. So far so good.

Can not say enough about the tremendous service we received. What started as a estimate on our system turned out to be a save as pipes in the aerator had broke and our time with having water at all was near the end. Mark immediately put a plan into action and our system is in and working great. In comparing with other systems we received a tremendous value at a reasonable price. I can certainly see why they have such high reviews.Thank you Mark and crew!

Called that morning after my usual (3+ years!) company did not return my phone calls after more than 24 hours since I noticed the issue. Was told someone could come out Friday morning, at the latest, unless a tech became available before then. I was unsure what to do, so I agreed. To my surprise, I got a call at 3pm that a tech was available. I was relieved that, at last, someone was on their way to help! Cody arrived and went right to work. He was professional, knowledgeable and respectful of the property and most importantly, fixed my well leak. It started raining (of course), and he kept plugging along, making progress. He kept me in the know with what he was doing. After an hour, the parts were replaced, and an invoice was produced which was more than fair. I am overjoyed that I found a company (and a tech) that surprised me in a good way. I will be calling Certain Services if I need help again. I much appreciated their responsiveness. Thank you!
