Frequently Asked Questions

How hard is Ann Arbor tap water?
Moderately hard — typically 8-12 grains per gallon (140-200 ppm). A 32,000-48,000 grain softener handles a typical 4-person home.
Should I test my Washtenaw County well?
Yes — at minimum annually for total coliform and nitrates, every 2-3 years for iron, manganese, and pH.
Is RO worth it?
For most users, yes — Ann Arbor TDS often runs 250-400 ppm. Under-sink RO at $400-$900 installed reduces TDS to 10-30 ppm.
