Have you started noticing any discoloration in your home’s water? Is your water heater leaking? Reddish-colored water and leaks are common signs your water heating system is starting to rust.
The typical water heater is lined with glass-lined steel. As such, if water finds an imperfection in the glass, it’s only a matter of time for the steel tank to begin rusting from the inside out — unless you stay on top of maintenance.
