Answer :
Final answer:
Hot water heater tanks are protected from explosion by the insertion of a temperature and pressure relief valve (T&P valve). The T&P valve automatically releases hot water and relieves pressure if the temperature or pressure inside the tank exceeds safe levels. It prevents the tank from exploding by venting excess heat and pressure.
Explanation:
Hot water heater tanks are protected from explosion by the insertion of a temperature and pressure relief valve (T&P valve).
The T&P valve is a safety device that automatically releases hot water and relieves pressure if the temperature or pressure inside the tank exceeds safe levels. It prevents the tank from exploding by venting excess heat and pressure.
For example, if the water heater thermostat malfunctions and continuously heats the water beyond its safe operating temperature, the T&P valve will open and release the excess pressure and hot water to protect the tank from exploding.
