Inspected an old family cabin and found this old water heater in the laundry room. Notice the rusted, capped metal pipe in the middle. That is where the pressure/temperature relief valve is supposed to go. Without this critical safety device the water heater could explode and cause significant damage to the house. I advised the homeowner to have the water heater replaced immediately!!! For more information visit: https://americanhomewater.com/can-your-water-heater-explode/
