Water Filtration and Water Treatment System Repair

It’s important to keep your family or business’s water safe and pure.

Whether you’ve had a water treatment and filtration system installed by Capital Well or have moved into a home with an existing system, we can service, maintain or update it to make sure you have no interruption in clean, pure water. It’s important to make your yearly service appointments to maintain peak performance, and in some cases, the warranty of your whole-house or point-of-use system. Have an emergency? We will quickly assess the situation and make the necessary updates or repairs.


Need supplies? At Capital Well locations we inventory water softeners, salt, polish cartridge filters, sediment filters and water quality consumables. With over 30 years experience, having your water filtration and treatment system serviced and maintained by our factory trained technicians at Capital Well Clean Water Center will bring you peace-of-mind when it comes to always having clean water for your home or business. Call us today to schedule a service appointment 1-800-924-1192.
