What New York conditions mean for plumbing
Statewide, the freeze class is hard: Buffalo and Rochester winters bury frost deep, and burst prevention belongs on every fall checklist. Water tells a different story. New York City supply typically runs soft at about 32 mg/L, under 2 grains per gallon in the DEP's 2025 supply report, so scale is rarely the enemy there. Buffalo's Lake Erie supply averages about 95 mg/L of calcium hardness (5.5 gpg), moderately hard. Elsewhere, hardness depends on your local supplier.
| Utility area | Hardness | Class | Source |
|---|---|---|---|
| New York City | 32 mg/L (≈1.9 gpg) | soft | utility report, 2025 |
| Buffalo | 94.8 mg/L (≈5.5 gpg) | moderately hard | utility report, calcium hardness, 2025 |
