Frequently Asked Questions

How do I know if I need a water treatment system?+
The best way is a free water test. Common signs include white buildup on faucets, dry skin/hair after showering, spots on dishes, and water that tastes or smells off. We test for 12+ contaminants to give you a clear picture.
How long does installation take?+
Most whole house systems are installed in under 3 hours. Reverse osmosis systems take about 30 minutes. We handle everything from plumbing to testing, and clean up after ourselves.
What does the 12-year warranty cover?+
Our warranty covers all equipment components including tanks, valves, membranes, and media. If anything fails due to manufacturing defects or normal wear, we replace it at no cost.
Do you offer financing?+
Yes. We partner with financing providers to offer affordable monthly payment plans that make water treatment accessible for every budget.
How often does the system need maintenance?+
We recommend annual maintenance to ensure optimal performance. This includes checking and replacing filters, testing water quality, and inspecting all system components. Contact us for maintenance plan options.
What makes Water2O different from other water companies?+
Three things: we test before we recommend (never guess), we custom-engineer every system for your specific water chemistry, and we provide 24/7 direct support from the same experts who designed your system.
