What To Do When Your Gas Water Heater Isn't Giving You Hot Water

Your water heater is designed to give you hot water. However, it doesn't always work like that. If your gas water heater is not giving you hot water, there are a few things you can do that will help ensure that you get the hot water you need again soon.

Check the Gas Supply to Your Water Heater

The first thing you should do is check the gas supply for your water heater. Generally, the gas line is a yellow tube. At the end of the yellow tube or gas line is a shut-off valve, similar to the shut-off valves for your water system.

On most hoses, if the gas line handle is positioned so that it runs parallel to the gas line, that means that the gas is on. If the gas line handle is positioned so that it runs perpendicular to the gas line, that means the gas is off. If for some reason the gas is in the off position, or partially off position, turn the gas handle so that it runs parallel to the gas line.

Check the Pilot Light to Your Water Heater

All gas appliances have a pilot light. The pilot light is what ignites the burner when your water heater needs to heat the water. Generally speaking, the pilot light is on at all times.

If your pilot light for your water heater has gone out for any reason, you are going to need to relight the water heater. 

There should be directions on the side of your water heater that let you know how to relight the pilot light. It is usually as simple as turning the knob for the pilot light on. If the pilot light has gone out, you will need to wait a while to allow the burners to heat the water again to see if that fixes your hot water problem.

Check the Sediment Build-Up

If the gas is running to your water heater, and the pilot light is on, you may have too much sediment in your water heater. Over time, as minerals break up in your tank and dissolve, little bits of debris get left at the bottom of your hot water heater. As that debris builds up over time, it can make your heater less effective, as the debris creates a layer between the heat and the water in your tank. To fix this, you need to wash out the water heater tank and probably install a water filter as well to remove the debris before it ends up at the bottom of your tank, preventing you from getting piping hot water.

If you need help troubleshooting and fixing your hot water heater, call up your local plumber. They will be able to come out, figure out what is wrong with your gas water heater, and get everything running again.
