⚠️ Indianapolis Water Hardness: 16–17 GPG

Citizens Energy Group serves approximately 875,000 people across the Indianapolis area drawing from the White River and Eagle Creek Reservoir. At 16–17 grains per gallon, Indianapolis water is classified as very hard. Most tankless water heater manufacturers recommend water below 11 GPG — Indianapolis water at 16+ GPG exceeds that threshold, accelerating scale buildup in heat exchangers and voiding some warranties without a softener in place.

🏠 Indianapolis Housing: Median Build Year 1977

Marion County's median home construction year is 1977 — meaning the typical Indianapolis home is nearly 50 years old. Homes from this era commonly used galvanized steel supply lines, cast iron drain stacks, and early copper piping. Galvanized steel corrodes from the inside out, reducing water pressure and eventually failing entirely. If your Indianapolis home was built before 1985 and has never been repiped, it's worth having a licensed plumber assess the system before a failure forces the issue.

My Indianapolis home was built in the 1960s or 70s — what plumbing problems should I watch for?

Homes from that era in Marion County typically have galvanized steel supply lines and cast iron drain stacks. Galvanized steel corrodes internally over 40–50 years, restricting water pressure before eventually failing. Cast iron drains crack and root-intrude with age. Signs to watch: rust-colored water, low pressure at multiple fixtures, slow drains throughout the house, or gurgling sounds. BNC offers whole-house assessments — call 317-352-0780 and we'll give you an honest picture of where things stand.

Does Indianapolis's hard water really damage tankless water heaters?

Yes — and faster than most homeowners expect. At 16–17 GPG, Indianapolis water exceeds the hardness threshold most tankless manufacturers specify in their warranty terms. Scale builds inside the heat exchanger, reduces efficiency, and can cause premature failure within 5–7 years on an unprotected unit designed to last 20+. BNC installs whole-house water softeners alongside tankless systems specifically to prevent this. If you already have a tankless unit, ask us about a descaling service and softener assessment.
