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.

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!

Certain Services installed our water system seven years ago. During those seven years we have had no major problems. We have had a few minor, normal wear and tear, issues that, with a phone call were dealt with at a very reasonable cost, usually the same day or the next. The technicians are great and are more than willing to answer any questions that you might have in language that you will understand no matter your skill level. I would advise anyone with a plumbing or water problem to call this company.

Joe came out to repair my well Saturday afternoon! If he hadn’t I would have had to move my horses to another location for access to water! Certain Services is the best monthly maintenance servicer I have found in Charlotte County, and the fact that they are available on weekends for emergencies seals the deal for me. I give them the highest ratings across the board.

A follow up to my previous review...Absolutely wonderful!I have lived in this house for almost 13 years. This was my first experience with a well water system. Up until recently I've never had any problems, but I've always had that fear. The first problem we had was a few months ago and I didn't know who to call. Luckily, I called Certain Services. It was almost 5pm on a Friday, but you sent someone out within an hour and we were back up and running within an hour after that. What a relief. This time, I knew who to call, but didn't know if I could count on having as good an experience the second time around. I did! It was around 7:30AM when I discovered we had no water. Your answering service picked up my call. A few minutes after that a technician called me back. He assured me someone would be out to my house that day, but since he was going into a meeting, he asked me to call the office at 8:00 when it opened. I did that, and again was assured someone would be at my house that day. By early afternoon the problem was solved very quickly. The technician, Nick, knew the exact cause of our problem and fixed it right away.I can't tell you how stressful it is to not have water, but I also have peace of mind now knowing who to call when a problem arises. I can't thank you all at Certain Services enough.******I can't thank you enough for the quick and expert service we received from your staff on Friday.My husband called me at work around 4:30pm on Friday and told me we had no water from any of our faucets. We had been having water pressure issues and our dishwasher wasn't working, but I was shocked to hear him say "NO water". And it was close to 5pm on a Friday. I was in a panic. We have a "home warranty", so I called them first, but, I was told that wells weren't covered. I did a quick Facebook and internet search for recommended well contractors, but nothing looked right to me until I saw your website. It seemed to cover everything and didn't require me to make a diagnosis before calling.It was 4:45pm when I called and I was hoping you were still open. Amy was an angel on the phone and I soon stopped panicking. I packed up at work and headed for home. I was so surprised to see your truck already parked in front of my house when I got home! An hour later and a few good tips from Cody and our water was restored. We didn't have to cancel our weekend plans or board our dog and check into a hotel. And I didn't feel "ripped off". I felt taken care of and valued.Thank you and thank you to your staff for being so professional and caring.

I was having trouble with my well system, the pump motor cycled several times after the water was turned on in the house. I called Certain plumbing as I have used them before but didn't expect a repairman until next week, not only did they send a repairman out right away but they sent the boss. Needless to say he knew what he was doing and repaired the system and did a few extra things to. The bill was very reasonable too.

We awoke one morning to no water. I called Certain Service. They responded quickly. They had a tech in the area. After completing that job,Nick responded to our call. He immediately identified the problem and made the repair. He then checked all the equipment and found our softener was not working. Another quick fix. He answered my questions and was very explanatory on what he was doing. I will “Certainly” use this company without hesitation. We awakened to water this morning! Thanks Nick and Certain Service.

We had just bought our home and the second week our well pump failed. We were also interested in treating the water. We called Certain Services and they came out the next day. Jeremy came out amd was very informative and helpful. Being new to Florida we had no idea how bad the water can be. After a thorough water test we discovered that our well high has a very high salt content (which explained the white build up on the faucets). Jeremy gave us our options for fixing the water and we decided to go with a whole house R.O. system. 2 days later, Joe, Nick, and Cody arrived to install the system. All three guys were great! Very friendly, knowledgeable, clean and efficient! We LOVE our water! wonderful experience from start to finish!

Needed a new water system to replace the old one. Didn't know exactly what I needed and so many I got a quote from said I needed a whole house RO system around $7500-10,000.Called Certain. Salesman came out, took water sample and analyzed it and I got a system that has no aerator tank to get moldy. Mys system is the newest technology installed by friendly, knowledgeable tech. My system went offline and I didn't know it until they called and sent a tech out the next day to get it back online...no charge.Quality equipment and quality company!They have earned my trust and business!

Our water suddenly went out late in the evening. We left a message with the phone service and Cody called us back within minutes. After having my husband try a few things, he came out quickly. Cody changed out the faulty switch and we had our water back in no time! He was professional, courteous, and prompt. The after hours call fee was the most reasonable fee I have encountered in years. You can bet we put their number in our phones as we won't even consider anyone else should the need arise for more service.

The employees at Certain Water Services always come right out when we have a problem and fix it as quickly as possible. A couple of times they were able to just walk us through what to do over the phone, saving us the cost of a visit. They recently installed a new water softener for us and they came on time, got it installed correctly, and took away our old equipment. This is the company we use for all of our water needs.

We are extremely happy with the service provided by Nick to get our system back up and running. He was knowledgeable, thorough, and explained what different parts of the system were and how they ran. This was especially useful as we do not have much experience with using a well as our primary water supply. He fixed the problem we had in a timely and cost-effective way, and was very professional and helpful. We will definitely be utilizing Certain Services for our future water needs!
