To improve your home’s water quality, install a whole-house water filtration system to remove contaminants like chlorine, lead, and bacteria, and consider a water softener to reduce hard minerals that can cause buildup in pipes and appliances. Regularly flush your water heater to eliminate sediment, which affects water taste and appliance efficiency. Lastly, ensure routine maintenance of filters and consider upgrading any corroded or outdated pipes to modern, safe materials to prevent impurities.
