Every home has different water conditions. Whether your property uses private well water or you want low-maintenance scale protection without salt, Zenith can test your water and recommend a system suited to your water chemistry, household demand and treatment goals.
Custom whole-home treatment for private wells helps address iron stains, sulfur or “rotten egg” odors, manganese, sediment, turbidity and other challenging water conditions. Each system is professionally sized following a detailed water analysis to deliver cleaner, clearer and better-tasting water throughout your home.
Key benefits:
Important: Every Zenith recommendation starts with a free in-home water test, a professional digital analysis that tests 7 contaminants in under 2 minutes and shows you exactly what’s in your water, not old-school test strips. For deeper concerns, paid certified lab testing is available covering 150+ contaminants.
Protect plumbing, fixtures, water heaters and appliances from hard-water scale without salt, chemicals, electricity, regeneration or wastewater. Filtersorb® media helps reduce scale formation while preserving naturally occurring calcium and magnesium.
Key benefits:
Important: A salt-free conditioner helps control scale but does not remove hardness minerals or produce truly softened water. Its suitability depends on your water chemistry and treatment goals.

No. A softener treats hardness minerals throughout the home. A reverse osmosis system provides advanced filtration for drinking and cooking water at the kitchen sink. Many Indianapolis homes benefit from having both.
Zenith considers your water hardness, household size, water use, plumbing, and available space. We confirm these details during your free in-home water test.
No. The Guardian RO800 uses a compact, tankless design that saves considerably more under-sink space than a traditional storage-tank system.
All reverse osmosis systems send some water to the drain during filtration. The Guardian RO800 uses an efficient approximately 2:1 purified-water-to-wastewater ratio.
Maintenance depends on water quality and use. The system tracks filter life, and Zenith can provide professional filter replacement and system servicing.
Yes. After testing your water and reviewing your needs, we provide a clear system recommendation and written quote.
Yes. Your initial in-home water test is free, with no obligation to purchase a system.
