We all deserve to feel safe at home. That’s one reason why home security systems are so popular. However, there are some safety risks that all homeowners should be aware of, especially when it comes to essential appliances like water heaters.
A water heater is a necessary appliance and generally not something to worry about. Although rare, a tank water heater does have the potential to burst or explode, creating a dangerous situation and leading to costly water damage. There are three main reasons why a tank water heater may burst: excess pressure, sediment build-up, and rust. In most cases, these dangerous situations can be avoided with proper water heater maintenance by a licensed plumber.
Excess Pressure
Some pressure is normal and necessary inside your tank water heater. The internal pressure is typically between 50 and 100 PSI. However, too much pressure can be very dangerous. As cold water is heated, the volume expands ever so slightly. If the excess pressure is not released, it will start pushing against the walls of the water heater, eventually causing a leak or explosion.
Fortunately, every modern water heater is equipped with a temperature and pressure relief valve (TPRV). If the pressure gets too high inside the tank, the valve opens to release water until the pressure returns to a safe range. It’s important to test this valve as part of routine maintenance to ensure it isn’t worn out or stuck. You should also make sure the temperature isn’t set too high, which could lead to excess pressure. The recommended temperature is 120° F.
How to Test the TPRV
- Locate the TPRV: The TPRV is usually found on the side or top of the water heater tank.
- Lift the Valve: Gently lift the valve to allow a small amount of water to release. This will help ensure that the valve is functioning properly.
- Check for Leaks: After testing, make sure there are no leaks around the valve.
Sediment Corrosion
The water supply that fills the tank contains a small amount of minerals. If you’ve heard of “hard water,” that refers to water with higher levels of calcium and magnesium. On their own, these minerals are not concerning as they naturally occur in water and do not pose health risks. However, inside a water heater, these minerals tend to settle at the bottom of the tank and accumulate into larger deposits. This build-up can disrupt the heat transfer and corrode the inside lining of the tank. Over time, this sediment contributes to a water heater bursting.
How to Manage Mineral Build-Up
- Drain and Flush the Tank: Regularly draining and flushing the tank can help remove sediment that has accumulated at the bottom.
- Water Softener Installation: Consider installing a water softener if your home has hard water. This will reduce the amount of minerals entering your water heater.
Steps to Flush Your Water Heater
- Turn Off the Water Heater: For electric models, turn off the power at the circuit breaker. For gas models, turn the thermostat to the “pilot” setting.
- Connect a Hose to the Drain Valve: Attach a garden hose to the drain valve located at the bottom of the tank.
- Open the Drain Valve: Allow the water to flow out through the hose. Be cautious, as the water will be hot.
- Flush with Cold Water: After draining, open the cold water supply valve to flush out any remaining sediment.
- Close the Valve and Refill: Close the drain valve, remove the hose, and refill the tank with cold water. Turn the power or gas supply back on.
Rust
Another way that a water heater deteriorates from the inside is from rust. That’s why most water heaters have a replaceable part called the sacrificial anode rod. Made of magnesium or aluminum, the anode rod attracts the corrosive elements that cause metal to rust. The rod breaks down over time but preserves the inside of the tank. Once the anode rod is fully corroded, it needs to be replaced. Depending on your water’s mineral content, you can expect to replace the anode rod about every three years or so.
How to Replace the Anode Rod
- Turn Off the Water Heater: As with flushing the tank, turn off the power or gas supply.
- Locate the Anode Rod: The anode rod is typically located on the top of the water heater.
- Drain a Few Gallons of Water: Drain a few gallons of water from the tank to reduce pressure.
- Remove the Anode Rod: Use a socket wrench to unscrew the anode rod.
- Install the New Rod: Insert the new anode rod and tighten it with the socket wrench.
- Refill the Tank: Turn the water supply back on and refill the tank. Restore power or gas supply.
