What causes water heaters to fail?
It’s not really often that we pay much attention to our water heaters, until they fail. We get one, install it behind a door or in the garage, and go on to our day with a fresh hot shower. Just like every other appliance in a household, water heaters will eventually stop working. This article aims to give insight as to what may be wrong with your water heater.
Before we jump to the facts on why they fail, these are the signs you have to watch out for of a failing water heater:
1. You only get cold showers.
2. Your water doesn’t get as hot as it used to be.
3. Your heaters make odd noises like a rumbling one.
4. The water that comes out is discolored, muddy, rusty, and has a distinct smell and taste.
5. Water leakage around the heater.
If even one of these signs presents itself to you, then it is time to start taking action and calling a professional. The components of a water heater were not made to last long, but the good thing is most of its parts can be replaced without buying a whole new water heater. These are the reasons of why they fail, and how to fix them:
1. Rust: the way these things were built are not made to last long. Highly active metal rods called “Sacrificial Anodes'' prevent the heater from corroding. In the process of usage, these anode rods are consumed and will eventually need to be replaced. While they do typically last some years, it’s always worth it to get a good check for rust and wear on your anodes. If they look worn down, then it is about time to replace them.
2. Build up of sediment: deposits of minerals go onto the bottom of the heater when water is heated, and as sediments build up, it reduces the efficiency of the water heater, thus causing it to be damaged. To fix this, drain your water heater at least once a year.
3. The size of the heater: Appliances vary in shape and sizes, and water heaters are no exception. If you are going to buy a water heater, make sure that you buy what will fit your needs. Buying a water heater that is too small may lead to more issues and breakdowns since it would need to work harder to get you hot water.
4. Loose parts: if you are experiencing water leaks, then it may be wise to check for some loose nuts or bolts first. If you spot one, tighten them up and see if the problem still persists. If there are still issues then it is time to contact a professional.
5. Old age: Water heaters typically last a long time, somewhere between 8 to 12 years. Beyond that and you should start looking to replace it with a newer model that is more efficient and up to date with technology.
Important Reminders
Though most of these things are stuff you can do by yourself, it is still important to be cautious as water heaters are dangerous appliances to tinker with. They are tanks filled with pressure and boiling water, so we advise you to just call a professional right away. The best way to do safety checks by yourself are spotting the signs of an aging or failing water heater, then seeking professional help to get them fixed.
