by Andy Butler

A hot water system is a key appliance in most homes. It provides hot water for showers, dishwashing, laundry and more. So, when a water heater starts to fail, it can be a significant inconvenience. Keep an eye out for these five signs that your water heater needs to be repaired or replaced. Read on to find out everything you need to know!

1. Not Enough Hot Water

If you find that you're not getting as much hot water as you used to, or if the water isn't as hot as it used to be, it's a sign that your water heater is failing. This issue could be due to a problem with the heating element, thermostat or another component of the system. 

2. Leaks

Water heaters have a fixed lifespan before they need to be replaced. If you notice water leaking coming from your heater, it's a sign that it's nearing the end of its life and may need to be replaced. 

3. Strange Noises

If you hear unusual sounds coming from your water heater, it's a sign that something is wrong. Some common sounds that indicate an issue include banging, popping and hissing. These noises could be a result of sediment buildup in the tank. Sediment buildup can also lead to other problems, such as corrosion and decreased efficiency. 

4. A Foul Odor

If the hot water from your faucet starts to smell bad, it's a sign that there's something wrong with your water heater. A common cause of this issue is corrosion affecting the inside of the tank.

5. Rust-Colored Water

If you notice rust-coloured water coming from your faucets, it's a sign that your water heater is starting to rust on the inside. Hard water deposits in the tank usually cause this issue. Rust-coloured water is not safe to drink or bathe in. It is a great idea to contact a plumber as soon as possible. 


A water heater is an essential appliance in most homes, but they don't last forever. You should keep a careful watch for these five signs that your water heater needs to be repaired or replaced so you can avoid being left without hot water. If you notice any of these issues, you should contact a plumber immediately so they can repair or replace the system and ensure it is safe to use.
