Why is my Gas Hot Water System not Working?

When you have no hot water, you can immediately figure out that your gas hot water system is not working. You might start checking if the gas line supply is on.

If it is, then examine if the pilot light is lit. If igniting it does not work, the problem might lie with the thermocouple. The thermocouple is the safety device that signals your gas valve whether the pilot light is on. The gas valve does not let gas pass through the burner which explains why you don’t have any hot water coming out.  In other cases, there is hot water but the supply is not enough. It could be that there is something wrong with your thermostat setting or the gas valves need replacement. 

It’s a different case altogether if you see that your gas hot water is leaking. Better turn the gas supply immediately and leave the area before you inhale too much gas. Contact the Plumbing and Electrical Doctor immediately to further diagnose and consequently fix the gas hot water issue. The solution could be as simple as replacing the flue piping to as serious as hot water tank replacement.

    2. Pressure relief valve – You might see water pooling below the tank but there is no mark or evidence of tank leaking. Check the thermostat and the water pressure does not exceed the standards between 50-60 psi.
    3. Drain valve – Sometimes leaking occurs around the drain valve. You need to flush your water heater before you can perform a drain valve replacement.
