Hot water is a necessity for every home. Showering, washing laundry, and cleaning require it and a heater provides it. Like many other appliances, sometimes these heaters have problems. Many people just switch out the whole unit with a new one, but repairing the one you have can be easier on your budget. There are signs that indicate you should replace hot water heater parts.
Not enough hot water is one issue. A complete absence of it is rather obvious, especially if you expected a relaxing shower only to freeze. When you start out with hot but it runs out before it should, the heating element could be the cause. This part is what heats the cold water in the tank, and a bad one can be quickly fixed.
Rust colored water is a sign of a problem inside the tank. Generally, this is not an area that can be fixed. You will need a whole new unit. Before you run out and buy a new one, you should first check that your utility company has not run a maintenance flush, which can cause rust from the lines to get deposited into your supply.
Leaking is a common occurrence. There could be two things to blame. Either there is an accumulation of sediments or there is too much pressure. Sediment build ups are normal and can be avoided by draining the tank periodically. The pressure can be reduced by adding a regulator.
Lower than usual temperature indicates a faulty thermostat. To check, look at the current setting and test at the faucet with a thermometer. If the two do not match, turn up the thermostat and retest. If they still do not match, get a new one.
Sometimes you may notice a putrid stench. Instead of getting rid of your heater, there are two ways to get rid of the smell. The liquid from your faucets and in your tank smells so badly because of bacterial growth in the water. In homes without children, adjusting the thermostat above one hundred thirty degrees to stop the growth. You can also try adding peroxide to the tank water if you are not able to raise the water temperature. The peroxide will accomplish the same goal.
It is often simpler to replace hot water heater parts instead of the whole thing. When one part is to blame, it makes sense to use the rest of the unit. When you exchange something, always inspect the remaining sections for damage.
