Due to a long life span of one to two decades, most individuals will never have to worry about replacing a dysfunctional water heater. Regardless, they should still be aware of possible problems that may arise, because an overlooked problem with your water heater can be cataclysmic. The following are water heater problems that could potentially arise:
A Lack of Hot Water
Have you ever been taking a nice hot shower, when all of a sudden the water turns icy? If so, it may be the result of a larger demand for hot water than your water heater is capable of supplying. Roughly 75% of the capacity of a water heater should be hot water. The amount of water, in gallons, that your household requires determines what the size of your water heater should be.
There is also the possibility of a faulty dip tube, which, if broken, can cause hot and cold water to merge in the tank. After inspection, if this does not seem to be the source of the problem, another possible cause is a cross connection. Because hot water heaters usually receive their water from the same supply as other household appliances, this possibility can be tested by turning off the water supply to your water heater. Then turn on the hot water tap of a faucet, and if water comes out, it could be a sign that cold and hot water are merging, resulting in a lack of hot water. If this is not the case, however, the likely cause is a faulty gas pilot or thermocouple. If so, they simply need to be replaced.
The most common of water heater problems is a decaying sacrificial anode rod. If you are experiencing rust colored water, the inside of your tank is corroding. On a positive note, due to the commonality of this problem, the sacrificial anode rods are relatively cheap to replace, running under $50 at hardware stores. In order to keep things working properly, you should monitor your sacrificial anode rod every 4-6 months.
If your hot water heater is giving off the smell of rotten eggs or sulfur, chances are your sacrificial anode rod is eroded. If it is severally corroded, bacteria form in the tank, which will cause the odor. To fix the problem, change out the sacrificial anode rod and flush the water heater with a hose from an outside water source. While this often gets rid of the problem, it can be a daunting and risky task. So if you are unsure, seek the help of a licensed professional.
A buildup of various matters in your tank could be the cause of the noise. But simply flushing out the system should clear up the problem.
Don’t automatically assume that the pool of water at the base of the water heater is a leak. In many cases, condensation is actually to blame. However, if after closer inspection you find that your water heater is in fact leaking, check the valve. If the valve is not the culprit, the tank may need to be replaced.
It is important to monitor your water heater regularly, because early detection of a problem is the best way to avoid further damage.
