No Hot Water in My Shower!

Why is My Shower Cold?

No hot water in your shower? Unless you have an on-demand water heater, the hot water for showers comes from your water heater tank. In order to provide the optimal comfort level, the water inside the tank must reach and maintain a consistent temperature. If your shower water does not get hot or stay hot, follow these troubleshooting steps to help you determine if it is time to contact a plumber.

Has anyone used hot water recently?

It takes time for the hot water heater to raise the temperature of the water in the holding tank to the desired level. If other members of the household have taken showers, washed laundry or run the dishwasher, they may have used all the available hot water.

Generally, 30 minutes is a sufficient time period to allow the water heater to heat additional water after the tank has been drained. If the water heater has a timer to save energy, ensure that you are showering during a time when the appliance is on. Verify that the water heater thermostat is set to the correct temperature

Check the other hot water faucets in the home.
  • If they are not receiving hot water or the temperature drops quickly, this is an indication that your water heater is experiencing a problem. It may be possible that one of the heating elements in the unit is malfunctioning, which causes the appliance to make an insufficient amount of hot water. If all of your faucets are dispensing cold water, the dip tube in the water heater tank may have deteriorated. As a result, cold water is probably being siphoned directly into the hot water pipe before it is heated by the unit.
  • If all the other faucets in the home are receiving sufficient hot water, the problem is more likely caused by a shower component, not the water heater. Cross-connected pipes or a malfunctioning mixing valve can cause the shower to produce only cold water. A worn out O-ring or a broken cartridge may cause improper mixing of the hot and cold water
