You should flush your water heater at least once a year, but ideally twice a year. If you have hard water, you should flush it every six months. Flushing your water heater removes sediment that can build up over time and cause problems: Reduced efficiency: Scaling near the heating element or heat pump can make it harder for your water heater to heat water, which can increase energy costs. Corrosion: Minerals in water can corrode pipes and plumbing systems. Safety issues: Scaling can block the pressure-relief valve, which prevents pressure from building up in the tank.
