4 Signs You May Need a New Water Heater

Like most major appliances in your home, water heaters break down after a period of time. Ideally, it would be best to replace your water heater before it completely stops working or starts causing water damage to your home from large leaks. However, most people have no idea that their water heater is about to fail and unfortunately run into big problems as a result.

Here are four major indicators that your water heater might need to be replaced:


If you turn on your hot water and notice that the water coming out from the faucet is a rusty color instead of clear, this is a tell-tale sign that the inside of the water heater tank is starting to corrode. When a water heater starts to deteriorate, usually rust develops around the tank seams, the temperature and pressure relief valve, the water supply lines, or the drain valve. If you notice muddy or sandy water from your faucet, that could be a sign of sediment build up in your tank.


It is important to pay attention to the noises that your water heater makes. While some sound is normal as the water heats, watch out for loud cracks and pops. Most noise issues are caused by sediment build up inside the water tank. As the sediment is heated and reheated, it eventually hardens. When the hardened sediment comes in contact with the heating element, it makes a lot of noise as it burns the sediment away. These sounds indicate an interaction between the heating elements inside the heater and the scale and mineral deposits built upon them.


If you notice standing water or leaking water around the water heater, it is best to call a professional right away since that is an indication of internal failure in the water heater. There is no quick and easy fix for a leaking hot water tank and you will most likely need to replace your water heater as soon as possible, in order to prevent flooding or further damage to your home. Make sure to disconnect electricity or turn off the gas unit and let the water cool down before attempting to remove and replace the water heater.


How long has it been since you last replaced your water heater? Most water heaters last an average of 10 years. If yours is older or you are not sure when it was last replaced, it may be nearing the end of its life. It is important to know the age of your water heater and you can find out the age by looking at the serial number on the manufacturer’s sticker on the upper portion of the water heater.
