Some Water Heater Problems


If you are like most of us, you don’t think about your water heater until you take a cold shower. Here are a few problems that can occur with your water heater on top of a cold shower.

1. Probably the most common issue related to water heaters is you don’t have hot water. This could be because of a faulty gas pilot or faulty gas pilot control valve. You might have a faulty gas thermocouple. The thermocouple is basically the gas pilot’s co-pilot. It senses if the pilot flame is hot enough to ignite the natural gas or propane fuel to the burner. If the thermocouple thinks it’s safe, then it will keep open the main gas valve. If it thinks it’s not safe, then it will shut off the gas valve.

2. The next most common problem, after not having any hot water, is not having enough hot water. Inadequate hot water can be caused by a number of things. You could have a unit that is undersized for your hot water demands, a broken or damaged dip tube allowing hot and cold water to mix inside your tank, or faulty plumbing installation crossed the hot and cold-water connections. You could even have a gas supply or control problem.

3. Taking a shower with rust colored water is never fun. If this happens you could be looking at corrosion inside a glass lined tank or your sacrificial anode rod is failing. The anode rod is designed to dissolve slowly to prevent rusting inside your tank from occurring.

4. Smell is an important part of our everyday life. What you don’t want to smell is a rotten egg odor from your hot water heater. This happens when bacteria in the tank sediment feed from the hydrogen gas inside your tank. The hydrogen gas comes from the decay of the sacrificial anode. Once the bacteria starts feeding, you get the nasty rotten egg stench.

5. Hearing noises like a low rumbling or high pitched whining should signal to you that something is wrong with your water heater just like when your car makes noises. The noise could be from water boiling in your tank. Excessive buildup of sediment in the bottom of your tank is causing your tank bottom to overheat and boil water.

6. Water leaks are never fun to deal with. Water puddles around the base of your water heater could be caused by a faulty temperature and pressure (T&P) relief valve or a T&P valve leak due to excessive pressure, overheating, or it’s stuck. You could even have a leak from a nearby or overhead plumbing connection or the tank itself is leaking from corrosion.
