When it comes to plumbing, Mr. Rooter is the one to call. Our trained and knowledgeable staff makes your satisfaction our main priority.

"The $7,000 project ended up costing us $123,000 because they dry-cut through the slab in our family room releasing asbestos dust throughout the entire house causing us to have to live in a Hampton Inn for 43 days. They cut the slab without supporting it and it collapsed enough to cause our brick fireplace face to have several cracks in it. With all the repairs we had to have done, the asbestos abatement project and replacing all our clothing, betting and some furniture, and with the amount our insurance company shorted us, we lost $43,000 of our retirement savings. Avoid this contractor like the plague!"

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.
