We rely on our water heater to get us through our daily lives. From washing the dishes to bathing and showering. However, at some point it’s inevitable that your hot water heater will need replacing. In order to minimise disruption, it’s best to pre-empt the failure of a water heater and replace them while they are still able to provide hot water and not have them break completely and be without hot water for days.
Here are a few ways that you could predict the failure of your water heater.
Rust In The Water
Checking the anode rod and replacing it when necessary will help you get a longer life out of your water heater. This rod attracts corrosive elements that are suspended in your water, which leads to them gradually rusting away, instead of the inside of your water tank. But, if you don’t replace it when needed, then it will stop working and the corrosive elements will then turn their attention to your water tank and start eroding that instead.
If you do have this problem, you may see rusty water coming from the taps. This can also be caused by rusty pipes, so check if it’s the tank or the pipes by flushing your tank and checking the colour of the drained water. If it does turn out to be your tank, then it’s time to replace it, rather than waiting for the point at which the erosion becomes so bad that the tank springs a leak.
Something Wrong With The Supply of Hot Water
If the water coming from your taps is running cooler than it usually does or noticeably faster, this could be a warning. It’s possible that this could simply be a heating element failure, which a qualified plumber can diagnose and replace, but it could also mean that mineral sediment has formed a coating on the bottom of your tank and on your heating element. This generally happens at around ten years old and indicates that your water heater is about to fail.
The Age of Your Water Heater
The average lifespan of a water heater is around 10 years. Over time, parts wear out, corrosion occurs, cracking can occur. If you don’t know when your water heater was installed, you can check by looking at the serial number. Manufacturers note the month and year that each unit is produced, so check their website for your serial number to determine the age of your water heater. If it’s over it’s ten year mark, then it’s time to consider replacement.
You’ve Sprung A Leak
Water heaters can and, if old enough, will, spring a leak; whether it’s due to corrosion, damage or something else. Check your water heater for leaks regularly and make sure you call a plumber at the first sign of drips or wetness.
There’s Strange Noises Coming From Your Tank
You may hear banging, sometimes loud, when your water heater is heating a tank of water. This a sure fire indicator that it’s on the blink. This is because the hardened sediment, mentioned earlier, forces your water heater to work harder to heat the water and that forces a rapid expansion of the tank itself. If the clanging and clanking becomes constant, it’s definitely time to part ways.
