Hot water is used a lot throughout the day, so if you don't have hot water, you're going to notice. Whether it's to shower/bathe, wash dishes or clothes, or to wash your hands, you need hot water. If you don't have hot water, you need to check a few things on your water heater. Read on for tips to help you troubleshoot and repair your water heater.
Check For Gas
Check to be sure the gas valve is turned on. If you don't have gas, you aren't going to have hot water. The gas lights the pilot light, which heats up the heating element, giving you hot water when you need it. Check the gas valve and make sure it's on. If it is on, check to be sure you don't have any leaks. You can check for leaks using soap suds. If you spot bubbles from the soap, you have a leak. If you smell gas in your home, call your local gas company right away.
Check The Pilot Light
If you don't have a pilot light, it's a problem. Check for gas first, then take a look at the thermocouple. If the thermocouple is bad, you won't have a pilot light, as the gas isn't going to be allowed to get to the pilot. Replacing the thermocouple can be done yourself, but if you don't know how to do this job, then leave it to a professional -- call an HVAC repairman for help.
Check For Water
If you don't have water in the tank, there won't be any water coming through your faucets either. Check that the water valve is on to your water heater. Also, check around your water heater for any water leaks surrounding it. Turn the water valve all the way on to be sure you have water.
Drain Your Water Heater
If your water heater has a buildup of mineral sediment at the bottom, it could cause your heating element to not be able to heat the water properly. If you have this buildup, you'll need to drain the water from your water heater. To do this, you'll need to turn the gas and water off to the water heater, then open up the relief valve and open the valve at the base of the tank after you've attached a garden hose to drain the water. The water coming out may be very hot, so be careful when doing this.
If you don't have hot water, you can try to make the repair yourself, or you can call your local water heater repair services for help making the repair.
