Temporary discoloration is common in Lower Manhattan due to sediment in older pipes being disturbed by construction, hydrant use, or water main maintenance. This is usually harmless and clears after running cold water for a few minutes. Persistent discoloration may indicate building-level plumbing issues.

Fixture-level: Only one faucet affected — check aerators or cartridges.

Building-level: Multiple apartments/floors affected — inspect risers, valves, or booster pumps.

City-level: Multiple neighboring buildings affected — likely related to mains, hydrant flushing, or infrastructure work.

Taste and odor can vary due to seasonal changes, hydrant flushing, or pressure shifts. Chlorine may be more noticeable in warmer months, and older pipes can temporarily alter flavor during flow changes. These variations are usually temporary and safe.

Run cold water from all taps for a few minutes to flush any sediment or discolored water. Check DEP advisories for updates. If discoloration persists, contact building maintenance to inspect internal risers or valves.
