Does Your Hot Water System Need To Be Replaced?

For many of us, instant access to unlimited hot water isn’t an option, and we count on our home hot water system to get us to the end of every shower and sink full of dishes.

But even the very best hot water heaters aren’t made to last for eternity, so unless we want to experience a periodic disruption and have no hot water, we have to be careful to replace older or failing units before they break down.

The ability to predict water heater failure is not an exact science, but there are a few general indications which could help you to determine beforehand when a heater is on it’s way out.


After several years of use, there are a number of things that can start to go wrong with a hot water heater.

Individual parts can wear out, corrosion can develop, or tanks can crack. For most water heaters, ten years is generally the maximum lifespan.

Knowing the precise age of your heater is important for those wanting to replace proactively. If you cannot remember exactly how long ago your heater was installed, or if you only recently bought your home, you can still determine the age of the heater by checking the serial number. Water heater manufacturers typically record the year and month a unit was produced in the serial number which is usually an alphanumeric code. If it is not immediately obvious you can check the manufacturer’s website to find out how to interpret this serial number.

Compromised Supply of Hot Water

When something is amiss with your water heater, the first sign is often immediately noticeable, namely in that your hot water is becoming cooler than usual, or it might be running out more quickly than it usually does.

This may be due to a faulty heating element, and this is something that a licensed plumber can determine and repair. On the other hand this problem can also be caused by sediment has that has coated and hardened onto the bottom of the tank, as well as onto the heating element. This kind of sediment build up typically reaches a need-to-replace state at the 10 years mark.

Rusty Water

In order to preserve the life of your water heater as long as possible, you should routinely check and replace the anode rod. This rod is used to attract corrosion in order to spare the tank itself, however it will gradually rust away altogether and need replacement in order to continue protecting your tank.

If the tank itself does become corroded you will eventually notice rusty water coming from your taps and shower head. To confirm that the problem is with your water heater and not with your entire plumbing system, flush the water heater tank and check to see if the water drained out is rusty. If your heater is indeed rusted out, it is time to replace it right away before it develops a leak.

When A Leak is Sprung

Whether because of rust, manufacturing defects, or damage, water heater tanks will eventually spring a leak at some point if they are neglected for too long. The best way to keep on top of this issue is to check your water heater regularly for dripping or even moisture and to take action right away to avoid a more serious problem.


Even if none of the problems listed above occur, a noisy banging sound might still announce that something is amiss with your hot water heater. When the above-mentioned sediment settles and hardens onto your tank, it makes the water heater work harder, which can in turn cause the tank to expand. If you hear a clanking coming from the tank as it expands, it is definitely time for a replacement.
