3 Reasons Your Water Heater is Leaking and Could Burst
Don’t let issues with your water heater get worse. If you observe any of the following problems, have a licensed professional make the necessary repairs right away.
1. Water Heater Sediment Build-up
If your water heater is making a popping or knocking noise, it may be due to sediment build-up. Over time, sediment—the minerals in water, especially hard water—will create a layer at the bottom of your water heater tank. This sediment blocks the water from the burner, forcing the burner to run longer to heat your water. This will cause overheating and deteriorate your tank faster.
This problem can be prevented by flushing and draining your home’s water heater tank of sediment once a year.
2. Water Heater Corrosion and Rust
Rust and corrosion can affect hot water heaters in different ways. If you notice corrosion on your water heater connections – the pipes or valves – it may be time to have those components replaced.
If your hot tap water is a brown, rusty color, you may be dealing with interior rust corrosion. Your water heater is made of steel. This means that over time, water will cause the tank to rust. This is why your water has something called an anode rod inside of it. This 3-5 foot rod draws rust away from your tank and corrodes in its place. So, once the rod deteriorates, your water heater is next.
To prevent this problem, inspect the anode rod at least once every two years. You’ll probably need to change the anode rod once every 4-5 years (or sooner if you have a water softener) to extend your water heater’s life.
3. Excessive Internal Pressure
If too much pressure builds in your water heater tank, it will eventually spring a leak or even burst. What causes too much pressure in a hot water heater? Excessive heat. Water expands as it heats up. If your water becomes too hot for your heater to handle, it could cause more pressure to build up than your tank can handle.
Luckily, your water heater’s tank has something called a T&P (temperature and pressure) relief valve. The T&P relief valve is in place to release water when the pressure increases beyond a safe level. However, even with the valve, the extra pressure can put undue stress on the tank over the years.
Test your valve periodically to ensure it’s working properly. If it isn’t working or if you notice corrosion on it, have your valve replaced. If you ever notice water pouring out of the pressure relief valve, call a professional plumber immediately.
Set the temperature of your water heater to 120-125° F. Any higher than that and you will increase the pressure in the tank and your chances of getting scalded.
