Water Treatment & Softeners in Dayton, OH

Dayton water-treatment contractors in this directory serve homes on Dayton municipal supply (treated, hard at 12-18 grains) and surrounding Montgomery County well-water properties. A whole-home twin-tank water softener runs $1,800-$3,400 installed. Well-water systems with iron filtration, softener, and RO at the kitchen typically land $4,500-$9,500.

Dayton's water hardness is among the higher municipal supplies in Ohio. Without a softener, water heaters scale within 2-3 years. Most installers run free in-home tests as part of the quote process.

Frequently Asked Questions

How hard is Dayton tap water?
Hard — typically 12-18 grains per gallon (200-300 ppm). A 48,000-64,000 grain softener handles a typical 4-person home.
Is RO worth it?
For most users, yes — Dayton TDS often runs 350-550 ppm. Under-sink RO at $400-$900 installed reduces TDS to 10-30 ppm.
Should I test my Montgomery County well?
Yes — at minimum annually for total coliform and nitrates.
