Eack HWT has an overpressure device mounted on the tank. It sounds like this one is leaking. Check the temperature setting on the tank to see if it has been changed. A HWT is not supposed to be operated at more that 50 PSI. Check the pressure reducing valve where it enters the house to see what the pressure reads.

If water is leaking from the top of the hot water tank, it is likely due to a faulty or damaged pressure relief valve or a loose connection at the inlet or outlet pipes. It is important to turn off the power or gas supply to the water heater and shut off the water supply before investigating further or contacting a professional plumber for repairs.Ignoring leaks can lead to further damage and potential safety hazards.

Why is your water tank not retaining hot water?

What is the anode in a gas water heater?

In a gas water heater, the anode rod is a sacrificial component that helps protect the tank from corrosion by attracting corrosive elements in the water. Over time, the anode rod corrodes instead of the tank, prolonging the life of the water heater. Regular inspection and replacement of the anode rod can help maintain the efficiency and longevity of the water heater.


How does a hot-cold Water Dispenser work?

A hot-cold water dispenser typically has two separate tanks - one for hot water and one for cold water. The hot water tank is heated using a heating element, while the cold water tank is cooled using a cooling system, such as a compressor. When you dispense water, the machine draws from the appropriate tank and delivers the desired temperature of water through separate spouts or taps.
