"Chad was great! We had a faucet leak that went from a slow drip to a big drip overnight? I called C & W first thing on Wed am and was put on the waiting list for Wed. Jennifer called at 3:30 to say Chad was enroute. He arrived 15 mins later. After looking over the issue, Chad gave us the quote and changed out a cartridge on the hot water side. It had been replaced 6 months ago by another plumber (not sure if it was a bad cartridge or other issue). He was finished in 20 minutes and no issues so far?. We will definitely use C&W again and will ask for Chad. Very courteous and fill confident about this repair."

"After trying different things and many nights of research, I decided to purchase a water filter system for my family, pretty much for these 2 reasons: getting rid of eczema I have been dealing with since I moved to North Texas and improve the taste of the water we drink every day! and after already a month with the system I couldn't be happier! Eczema is gone and my family is drinking way more water than before, and I always struggled to achieve that goal. Another thing is that the customer service was on point since the very first call to inquiry about the system and service, Ralph and Jake are great, they took great care of us and answered all of our questions! I did a lot of research before making my decision and I couldn't be happier that I went with them, clean installation, great professional service!"

"The installation itself went well, and the additional items promised were received. We negotiated for more items since we didn't need an additional RO filter. NOW here is the BUT. We do have satisfactory whole house basic filtration, BUT it adjusts the pH the wrong way for us. Sales person tested water but I don't think she was used to seeing high pH like we have out here. We really needed a different solution to take care of that, but that wasn't suggested. So our water is even softer now. This keeps us from being satisfied with what is a good product otherwise. Last periodic servicing January 2017, satisfactorily performed."

FAQs for water treatment & purification system repair or service projects in Dallas, TX

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.
