"Good customer service!!!! I called them Christmas eve because our water softener gave up. Chris answered right away and walk me through so we can have our water back. Really appreciate the quick response and the work they’ve done. Very thorough and detailed explaining the issues we had and gave us tips on how to care for the new system they installed. Worked with us also paying for the whole system."

"I just won a beautiful water heater from Legendary Service, and they were amazing. The installation was quick, easy, and clean. The owners came down personally to make sure everything went smoothly. Very nice people and I would definitely go to them for all my plumbing and heating needs!"

"Mark and his team have been a pleasure to work with over the years. Chicago Water Pros has performed exceptional service on my current and previous homes. Mark is always responsive, knowledgeable and professional. They came in and installed a water softener system for my whole home and a water filtration system for the kitchen sink. Chicago Water Pros crew is very courteous and clean, they ask permission, explain the process and even wear little foot protectors when entering my home. They had the items installed in 1 day, the results were instantious, the tap water became enjoyable not just drinkable. And the water is much softer making the showers more pleasurable and easier to keep clean. We have marble in our master and the water in our area has many minerals that will stain the stone if not treated. I highly recommend CWP Mark and his team for all water filtration needs."

"I have an RO under the sink water purification system which I have had for over 15 years. The man who installed the system and serviced me all these years retired. Out of necessity I had to find another company. The system Is unique and I was Concerned if I could find another company who would have the equipment and knowhow To change the filters. Angel had what I needed. In addition the angel serviceman showed me that the manifold needed replacing. I scheduled this. I am concerned about the quality of the drinking water in our house and I am glad I can count on Angel to meet this need."

"Installing the water system is a little expensive. The new water does taste great. However, after installing the system, they did not test the water, they just assumed everything was fine. After about 6 months, I noticed I had new calcification. I was at Costco and brought this up to the representative who said he was sending a message and I would hear from them. A week went by and nothing. I then had to call and set up an appointment. It took 2 visits for them to figure out the issue and a third to repair it. Even after fixing the issue, no one tested the water to prove to me that the issue was fixed. So now I am just supposed to wait for the year review of the water system to find out if it is working. For the thousands of dollars I paid, I feel I deserve visual confirmation that the system is actually working.

"Robert was fantastic and went above and beyond for us and our son with eczema.  Robert tested and explained just what was truly in our water which I never knew for 35 years.  We've only had it installed for a week but I can already see a difference in the water quality 1,000% and especially while giving the kids a bath.  I would recommend Titan Waters to anyone that does not have pure water in their house.

"Went very well. TDH services my two furnaces and one humidifier every autumn to assure trouble-tree operations. Their technicians have always been thorough, knowledgeable, efficient, friendly and professional; an this year's visit, by technician Gelacio, was no exception. Together with TDH's fair price, this keeps me a satisfied customer."

FAQs for water treatment & purification system repair or service projects in Lake Villa, IL

If your water softener is over 10 years old or if repair costs approach the price of a new unit, it might be time to replace it. Most water softeners last between 10 and 15 years. Replacing an aging unit can improve your water quality and help you avoid frequent repair costs. For a newer system with minor issues, repairing may be the best option. Consider the age and condition of your system to decide what's most cost-effective.

Water treatment systems remain dependable for 10 to 20 years with proper maintenance and care. A well-maintained system secures full performance by following a scheduled upkeep plan and professional inspections. Consistent maintenance guarantees continuous water purification, ensuring that the system operates at its peak efficiency and delivers high‑quality water throughout its lifespan.

Faulty water softeners exhibit clear symptoms that signal the need for immediate attention. Noticeable mineral build-up around faucets, discolored water, dry or itchy skin following a shower, and altered laundry texture indicate that the system is underperforming. Recognizing these issues early and addressing them promptly prevents further damage and maintains optimal water quality. Early intervention ensures that your water system continues to operate reliably and efficiently.
