Water heaters are a common appliance in most homes. Water heaters can last for years without problems in some instances, but that doesn't mean that they are indestructible. As your water heater gets more and more use it is important to check it often to make sure that it is safe to use and that it doesn't need repairs. Here are a couple signs that your water heater is failing.
1. Loud Noises
Water heaters will make a little bit of noise when they run. This is normal, but the noises should be more of a gentle hum rather than any loud noises, clanking or popping. If you notice any sounds coming from the heater, call for a repairman right away. By fixing the problem early you might be able to prevent total failing from the heater.
2. Rusted Water
When you run your water from a faucet does it have a rusted look or metallic taste? If so, this is a sign that you need to repair or replace your heater. With all the use that the water heater gets it is no surprise that over time there is a chance that it will rust over. If you get rust inside the machine it can erode the actual metal and compromise the quality and safety of your water.
3. Leaking Water From The Heater
Another sign that you need to replace or repair your heater is that there is moisture and water leaking from the unit. Even a small leak coming from the unit could cause major problems. It could cause more money in your utility bill as you waste water and have to heat more water than necessary, but it can also damage the unit and it's surroundings. If you see any water coming from the unit, or notice puddles on the ground around it, call immediately for repairs.
4. Lukewarm or Cold Water
One of the most obvious signs that your heater is failing is that the water is no longer warm. Before you jump to conclusions about the heater totally falling you should check to make sure that there is power to the unit. Sometimes the power will get disconnected, or if it runs on gas the pilot light could go out. However, if the water is slightly warm, like lukewarm that simply means that the heater is going out and needs to replaced.
By understanding what to look for in your water heater you can prevent major problems with your unit.
