As an Amazon Associate, we receive a commission on qualifying purchases made via our link. Get to Know Us a Little Bit Better! Clogged drain valves are the most common reason of a water heater that will not drain. As a result of excessive sediment build-up within the tank, this is a common occurrence. During the heating process, the minerals present in the water separate and fall to the bottom of the water heater. Not only will the silt diminish the efficiency of the device if it is not emptied on a regular basis, but it may also clog the drain valve and cause the water within the water heater to get trapped.
Clogs may be anything from a little nuisance to a significant problem, depending on their severity. This problem, if left ignored, will eventually need the purchase of a new water heater, as silt will tear down the inside of your tank, resulting in an unfixable leak.
To prevent the water from warming, the fuel source should be switched off.

Why Is My Hot Water All Of A Sudden Not Working

If your hot water tank is not receiving the necessary power, your heating element may be defective or have insufficient power. You may need to have a plumber come and inspect it to be sure. If your hot water is supplied by an electric hot water heater, it could be due to a tripped circuit breaker, a blown fuse, or a shorted element.
If your hot water is provided by a gas hot water heater, it could be due to a pilot light going out, a broken thermocouple, a blocked gas burner, or a defective gas control valve. In each case, it is recommended to have a professional come and take a look to identify and resolve the issue.

Turn Off The Water Heater
Shut off the gas to your water heater, or shut off the power if it is an electric heater. Now shut off the water, using either the valve in the cold-water pipe above the water heater or the main water supply valve to the house. Make sure the pressure is off by testing the hot water faucets in the house, turning them on, and checking for water. Water may gush out at first, but should quickly slow to a trickle if the water has been shut off properly. Be sure to leave a hot water tap open in the sink nearest to your hot water heater to alleviate pressure in the system.

How Do You Prevent A Water Heater From Clogging
After all the trouble youve gone through to have your water fixed, it is important that you take measures to prevent it from happening again. You may have hired a professional to fix it for you this time, but whos to say that it can be resolved again the next time? There will definitely be a next time, if you still overlook caring your unit.
First of all, you need to look into using a water conditioner, if you havent yet. Sediments are very common to hardwater, and if your unit has this issue, you are likely dealing with hardwater. Water softeners help remove the minerals that cause blockages in a water heater. Those that arent dissolved by the water softener will remain inside the tank.
This is why regular maintenance on your water heater is important, especially doing routine flushing or draining. By doing so, you prevent various minerals and sediments from settling on your water heater, causing blockage, and flush them away before they have a chance to solidify. These are the primary culprits for a clogged water heater.
