What type of leak your water heater may be experiencing can predict serious trouble. If your water heater is leaking from a relief valve or a drain valve, then that’s typically an easy fix. However, if your tank is leaking then that’s a problem! Because the tank is lined with glass and if that glass cracks your tank will leak causing the steel to rust eventually causing the tank to rupture. Usually the telltale sign that you have a crack is that you will see rusty puddles on the floor around your water heater. If you don’t replace your water heater the tank will rupture and flood your home. Don’t risk flooding! Replace that water heater now!
