How Do You Know If It's Time To Replace Your Hot Water Tank?

Posted on

Have you ever been caught in the shower with a sudden blast of icy cold water? You might think it's just bad luck, but your hot water tank might be the real culprit. Hot water tanks are essential to any household, but like all appliances, they have a lifespan. So knowing when to replace your tank can save you headaches, money, and a cold shower. What are some of the key indicators that it may be time to replace your tank and bring in a plumber to service your hot water system?


You can tell how old your hot water tank is by looking at the plate affixed to its side. If your hot water tank has been around the block, it's time to start thinking about a replacement. Unfortunately, it is likely to fail when it gets past a certain age, and while this can vary, you may be able to get more information by researching similar models on the web.


A leaking hot water tank is a sure sign that it's time for a replacement. Leaks might appear at the bottom, around the drain valve, or at the top from the fittings. Leaks can cause water damage to floors, walls and property, leading to costly repairs. If you notice leaks from your hot water tank, it's time to call a professional plumber to assess the situation.

Rusty Water

If your hot water is rusty or discoloured, it could be a sign that your hot water tank is rusting from the inside. Rusting can lead to leaks and other issues that require a replacement. Rusty water could also be a sign of sediment build-up, which can affect the efficiency of your hot water tank. Either way, a professional plumber should check out any rusty water immediately.

Strange Noises

Gurgling, popping or cracking sounds from your hot water tank could signal sediment build-up. This type of build-up can cause damage to your hot water tank, leading to a replacement. Strange noises could also indicate a faulty heating element or a damaged tank. In any case, it's time to call a plumber to assess the situation.

High Energy Bills

If you've noticed a steady increase in your energy bills over the months, your hot water tank might be to blame. As hot water tanks age, they become less efficient, leading to higher energy bills. A new, energy-efficient hot water tank can help save money in the long run. It's worth considering a replacement if you're experiencing high energy bills.

What to Do Next

Knowing the signs that indicate it's time to replace your hot water tank can save you from costly repairs, property damage and cold showers. You'll enjoy a hot shower and peace of mind by replacing your hot water tank before it fails altogether.
