SCHEDULE YOUR FREE WATER ASSESSMENT NOW
Regular water quality testing is important whether you use a public or private water supply. However, if you have a private well, the responsibility of ensuring your water meets drinking water standards falls on you, not the town.
We strongly suggest that you test your water regularly, at least once a year per the EPA’s recommendations. At H2O Care, our water specialists can help in determining the most sensible approach. We also provide many well water treatment options to keep your water clean!
Why Choose H2O: A Water Treatment Company Providing Superior Installation
At H2O Care, we apply advanced water filtration and water softener technology. Our licensed Master and Journeyman plumbers ensure quality workmanship and expert service.
We DO NOT contract out our plumbing work. This ensures a safe, controlled, professional installation to improve your overall water quality. We are not a franchise and can choose the best available equipment and technology to address your specific water quality issues. Our full-service staff will optimize your water filtration and treatment systems to ensure proper, long-term functioning.
We use cutting-edge technology, but only after rigorous testing of any new technologies. We are often contacted about trying new technologies, which we test internally and in the field to determine the actual potential value for our customers. If equipment passes our rigorous testing, it becomes available for future water quality improvement installations where appropriate.
