Home Fixer Guide

This page covers metal-like tastes and odors in household water, commonly described as a copper or pennies-like smell. These changes can be localized to hot water, a particular faucet, a shower, or an outdoor spigot, and often begin after plumbing work, outages, winterization, or pressure events. Some issues are worse after water sits and improve after flushing.
