Whether you need to replace your water heater depends entirely on where the leak originates. If the leak stems from internal tank corrosion, rusted bottom walls, or split structural seams, the tank cannot be repaired and must be replaced entirely. However, if the leak is caused by a loose external plumbing fitting, a faulty temperature and pressure (T&P) relief valve, or a replaceable gasket, you can simply repair or replace that specific component without buying a new unit. Verification: Inspect the tank closely to determine if the leak is internal or external.
