Heard about the MythBusters water heater video? Yes, it is true – the show MythBusters did prove that a water heater can and will explode – launching itself like a rocket straight through the roof of a house. And yes, this could happen in your business or commercial residential setting.
The cause of steam and pressure build up inside a water heater unit is usually caused by a faulty T&P (temperature and pressure) valve. If the valve is blocked, plugged or otherwise damaged it simply cannot release adequate pressure and the unit becomes pressurized – potentially resulting in an explosion. A simple and easy way to check your T&P valve is with the “lift test” – simply lift the lever and water should come out easily onto the floor. If you have reason to suspect that your T&P valve is not functioning properly, please call a trained water heater technician today. Do not leave this to any maintenance person or plumber – be sure they know what they are doing when it comes to water heater technology!
