Corrosion in the water heater: Are the black specks only

appearing when you turn on a hot water tap? This could mean corrosion in the hot water lines. But the more likely cause is a rusting hot water tank. This often occurs in older tank water heaters (more than 15 years old) or ones that haven't been maintained.
