Like most appliances, hot water tanks have an expected lifespan of 10 years. After that, they begin to lose efficiency and can cause more problems than they’re worth. Eventually, they might not be able to keep water hot enough for your home’s needs. They might also have leaks, breakage, or other issues that require replacement sooner than expected. However, there are some warning signs that indicate it’s time to replace your hot water tank instead of repairing it. If you see any of these signs, it’s time for a new water heater. Depending on the size of your home, hot water tanks can range from very small units that are mounted under the floor and cost less than $1,000 to very large units that are installed above the ground and can cost more than $10,000. Here are some signs that would indicate that it’s time for a new hot water tank: An increase in monthly bills - Water bills are usually the first thing that goes up when you have an older and less efficient water system. If your hot water tank is the source of your increase in bills, it’s probably time for a new one. It could also be due to an increase in the number of people living in your home or an increase in your water usage. A whistling or screeching noise coming from the hot water tank - This could be a sign of impending disaster. The tank is overheating and must be replaced as soon as possible. A pungent or putrid smell coming from the hot water tank - This could mean that the tank’s seals have failed and water is leaking inside the tank and out of your home. Water leaking from the tank isn’t just a hygiene issue; it can also cause damage to your property. Broken or leaking pipes - If your water pipes are leaking or broken, it’s important to replace the hot water tank as soon as possible to avoid damaging your home further. These pipes are the most important parts of your water system and must be kept in good shape at all times.
