Once your water heater is older in age, there’s a greater likelihood that a leak will occur. If don’t tend to any leaks immediately, then this could result in water damage to your home, which can end up costing you a lot of money in repairs. Several things can cause your water heater to leak, but the primary cause is when the metal tank expands and contracts due to the inner heating mechanism. Usually, your tank won’t leak when it’s idle, but when it undergoes a heating cycle, it will expand and begin to leak again.
At any rate, you should always check if any water appears under your tank. This can indicate that certain components of your water heater are defective, such as the fittings and connections to the tank itself. You can make adjustments and tightenings to try and stop the leaking, but if it’s coming directly from your tank, then you will need to replace your system altogether.
