Can a new water heater explode?
Electric and gas water heaters can explode if the pressure inside the tank is too high, failure of the temperature & pressure relief valve, or improper installation. With gas water heaters, flammable vapors or a gas leak can cause an explosion if a spark were to ignite the gas or flammable vapors.
What causes a hot water heater relief valve to leak?
This feature is not available right now. Please try again later. The two most common reasons for a hot water heater relief valve leaking are excessive temperature or excessive pressure. It’s rare that a hot water heater relief valve is faulty for no reason.
When does a water heater pressure relief valve open?
If at any point the temperature or pressure reaches an unsafe level, the water heater triggers the relief valve to open and release water out of the tank until the temperature and pressure return to normal. Reasons for water discharging from the relief valve
What happens when a check valve is installed on a water heater?
When a check valve is installed, it becomes a closed plumbing system. Because it’s closed the pressure in the system increases, as the heater heats the water. An expansion tank that is properly charged (charged to the “normal” water pressure) will “absorb” the pressure increase, keeping the system at a steady pressure.
Why is the TPR valve dripping on my new water heater?
Because it’s closed the pressure in the system increases, as the heater heats the water. An expansion tank that is properly charged (charged to the “normal” water pressure) will “absorb” the pressure increase, keeping the system at a steady pressure.

Is there a TPR valve on a water heater?
These questions and answers about TPR valves or temperature/pressure relief valves on water heaters were posted originally at RELIEF VALVE, WATER HEATER – be sure to review the diagnosis and repair advice given there.
