At Quality Water, Inc., we are your premier choice for water treatment systems. We have provided high quality work and friendly customer service for years. Call today for your free water analysis! I ONLY install equipment that I sell, so I can stand behind it.

"Randy and Zach are super professional. They promptly provided the water softener/RO with all the specifications and went into great detail to explain the system and its usage. I highly recommend these people. You cannot get this deal anywhere else."

"I had a very disappointing experience with Beacon Home Services. This company charges extremely high prices for even the most basic repairs. I needed a simple leak fixed in my gas water heater?a job that took no more than 10?15 minutes?and the cost was outrageously high. Their customer service was equally frustrating. They were rude, unhelpful, and promised to call me back but never did. The lack of professionalism was obvious at every step. I strongly recommend staying away from this company. Save your money and look for a reputable service provider that values honesty, fair pricing, and respectful communication."

FAQs for water treatment & purification system repair or service projects in Fairfax, VA

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.
