How Can I Tell If My Water Heater Needs to Be Repaired or Replaced?
Here’s how Mike Diamond will probably recommend fixing most common water heater problems and why:

My water heater doesn’t produce enough hot water
Possible causes:
- The thermostat isn’t set properly
- The tank isn’t big enough
- The tank is leaking
- The dip tube is broken
- The heating element is malfunctioning
Possible fixes:
- Reset and adjust the thermostat to the correct temperature (usually 120 degrees)
- Replace the tank with a bigger tank
- Patch the tank leak
- Repair or replace the dip tube
- Repair or replace the heating element
Verdict: An expert can probably repair the problem, but may suggest upgrading to a larger water tank.

Water takes too long to heat up
Possible causes:
- The heating element is malfunctioning
- Sediment or rust are preventing the element from heating the water properly
Possible fixes:
- Replacing the heating element
- Draining and flushing the tank to remove sediment
- Replacing the tank
Verdict: Replacing the heating element is a simple job. If too much sediment builds up, however, then experts will have to replace your tank.

My hot water is rust-colored or smelly
Possible causes:
- There is a high concentration of sulfates in your tank, probably from sediment buildup
- The anode rod is rusted or corroded
Possible fixes:
- Draining and flushing the tank
- Replacing the anode rod
Verdict: Replacing the anode rod is a simple repair job. If sediment buildup is too significant, however, then experts will have to replace it.

Valve or tank is leaking
Possible causes:
- If the tank itself is leaking, then it is corroded from the inside
- If a valve is leaking, then the temperature-relief or pressure relief valve may be damaged
Possible fixes:
- If the tank is leaking, the only fix is replacing it
- If valves are leaking, they may be able to be replaced without replacing the whole tank
Verdict: Determine where the leak is coming from. If the tank itself is leaking, call experts to help you replace it right away.
