"Amazing Install and Service. Turn around time to get us on the schedule was quick and even came back out the next day for a minor leak that needed to be addressed. As a veteran I truly appreciate the service this Vet Owned business continues to give the community at a fair price. Installers were friendly and answered all questions we had and even did a basic training on our new water softener system before leaving. You need better water...look no further! (and ask about the veteran's discount 😉)"

"I had a tankless water heater installed but needed the gas line to be dug from the other side of the house for it to be connected. The job was complicated but Luke and his crew from Mr. Rooter did a great job! I would totally hire them again for any plumbing needs. "

"The Plumbing Authority got back to me right away once I connected with them on Angi. We agreed on a date and time for them to come to my house and they were there exactly when they said they would be. Mikhail was very polite and professional and didn't try and "upsell" me anything. He kept the area that he was working in clean and when he left you wouldn't have known he was ever there except for the leak problem had been fixed. He completed the work very timely. I like The Plumbing Authority very much and would highly recommend them. "

"I live in Tellico Village and we were having issues with slow flushing and bubbling sound in the drains. I called WhizPro to come out. Online and on the phone I was told it is a $99 service fee to come out. That quickly changed $420 because it is considered ?complex? after he noted water in the sewer clean out pipe. The plumber mentioned it could be a problem with my grinder pump. I told him that the POA maintains that, and I would need to call them if this is the issue. He unsealed the basin lid and noted it to be full, indicating a malfunction. I went inside to call the POA Water Works. Meanwhile, he opened the electrical box for the grinder, which he later told me he is not supposed to do. He ran a voltage test and told me my grinder was ?burned out?. I told him the POA water works is coming, and they will manage the job from this point. He declined to reduce the $420 fee to $99 despite only taking off two lids. Would not recommend. "

FAQs for water treatment & purification system repair or service projects in Knoxville, TN

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.
