S sign is often a clear indication that your water heater needs to be repaired, rather than replaced. Here are some common signs that may indicate it's time for repairs:
- Leaks or cracks in the tank or sides
 - Corrosion on the tank or pipes
 - Thermostat not functioning correctly

Maintenance of your water heater can help prevent breakdowns and ensure it operates efficiently. Regular maintenance includes:
- Check the temperature and pressure relief valve to ensure they're functioning properly
 - Inspect the anode rods for corrosion
 - Check the electrical connections for any signs of damage or wear
 - Run a drain valve test to check for leaks
