"I was never so glad to answer the phone and talk to Mr. Jones about reverse osmosis drinking water. He gave me a true education! His son came to our home and installed a new system for us. There are many things that set this company high above the competition. First, their product is 'Made in America' and that pleased me a lot. The website, wow water, really explain how an R/O system works. The best part is the service this company provides after the installation. Austin arrived on time, was courteous, knew the product, and could answer every question I had. After the installation he cleaned up everything and showed us what to do with the new system. In addition, this company, Jones Air and Water, does more than install R/O systems. I highly recommend them and will be using them for other projects we'll be doing in the future."

"Called Sam on Friday for quote for water heater replacement. Said he could do Monday afternoon or Tuesday morning. Received call Monday morning to see if he could come on over to do replacement, what a pleasant surprise! Sam arrived shortly after with water heater we discussed & all supplies needed , no running around to pickup stuff. Job completed in timely manner. Old unit hauled off and job site all cleaned. That’s a big deal to me. Will not hesitate to recommend Liberty to friends & relatives ! Thanks Sam , Dave & Roxanne"

"We had Jones Air & Water come out to install filtration and replace a catalytic core system that we had installed to prevent descaling. In our situation, we had a high volume of Chlorine in the water that you could definitely smell and taste. The catalytic core system, didn't live up to the expectations and we still had to deal with a heavy scale build up noticeable on all of our faucets and with two Rinnai units for on demand hot water that raised concerns about what type of build up we were having on what we couldn't see. Everett came out and was very thorough in testing the water and then explaining a recommended solution. We finally decided on a dual media tank solution that Everett and JD installed that provides us with an efficient way to not only handle the Chlorine issue, but truly conditions the water and we're noticing all of the differences that Everett explained we should see. We are very satisfied with the whole process from the review of what our situation is, the recommended solution, the installation and the end result. We highly recommend using Everett for a water treatment solution."

"I called Burke Plumbing because my sump pump went out and flooded my basement. I was panicked. The person who answered the phone I think her name was Joanna calmed me down and said I would have Rob out in an hour. Rob arrived on time and replaced my sump pump. I don't know what I would have done without this company coming to my rescue. I will call them again if I have any other plumbing needs."

"John was extremely helpful in patiently exchanging many emails with me as I tried to determine whether I wanted to try a repair or a more expensive replacement of all the bath and shower hardware. He did not try to push me one way or another but rather simply conveyed what might work and the relative cost for Mayo to do the job. He was professional, knowledgeable, & promptly responded to questions. As it turned out I was able to replace a cartridge myself. However he will be my first call next time I need any pro for plumbing services."

FAQs for water treatment & purification system repair or service projects in Saint-Louis, MO

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.
