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.

  • Turn off the fuel supply for your water heater . Turn off the circuit breaker
  • Drainage should be connected to the drain valve and the valve should be OPENED. DEPRESSURE IN THE TANK: OPEN a hot water faucet inside your home to allow the negative pressure to escape
  • It is unlikely that your valve is clogged if the water drains and turns clean. Clogged valves cause the water to dribble or not drain at all
  • This indicates that the valve is clogged.
  • To prevent the water from warming, the fuel source should be switched off.

    Ever woke up with water that wont drain? Well, it must be one of the worst things to wake up to. But, if youre like me, who isnt naturally fond of learning the ways around my home, youre in for a treat.

    Why Is My Hot Water All Of A Sudden Not Working

    If your hot water is all of a sudden not working, it could be due to a number of issues. If your hot water is supplied by a boiler, it may be a problem with the boiler which could include low water pressure, a damaged component or component failure, or out-of-date settings.

    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

    To Drain or Not to Drain

    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.

  • Turn off the cold water supply valve at the top of the water heater. This pipe should feel cold to the touch. If it feels warm, you’ve got the wrong valve.

  • Near the bottom of the tank, locate the tank drain valve and attach a standard garden hose to the drain valve. Be aware that some models may have a cover over the valve opening.

  • Place the other end of the hose in a floor drain or on a driveway where it can drain safely. If necessary, buckets can be used, but be careful not to be burned by the hot water as you work. Make sure the end of the hose is lower than the valve on the water tank.

  • Open a hot water tap nearest to the water heater, preferably on the floor above. This alleviates pressure in the system, allowing the water to drain quickly from the tank, much like removing your finger from the top of a drinking straw filled with liquid.

  • Open the drain valve and allow the water to drain from the tank. Again, the water will be hot if you haven’t let it cool first, so use caution.

Its easy to determine which pipe is which one will feel cold, the other will be hot. Make sure you turn off the cold-water pipe valve. Again, we recommend turning off the gas or electricity to your water heater several hours before attempting to drain the tank to avoid the risk of scalding hot water. If youre unsure of how long to wait or are concerned about the risk, trust this project to a professional at your local One Hour Heating & Air Conditioning.
  • Take a moment to run the hot water from the faucet or another tap in the house. It should run, then slow to a trickle. Leave this tap on to relieve pressure in the system until youre done draining.

  • Re-open the hot water heater drain valve and let more water run through the hose. If youre filling a bucket, you will need to turn the drain valve off and on repeatedly as your bucket fills up and needs to be emptied. Its more time-efficient to let the hose drain directly outside if possible.

    One way to check this is by inspecting the water pressure and temperature at various places in the house. If certain spots have lower pressure or colder water than the others, then it could point to an imbalance in the plumbing system.

    If you are also having issues with hot water in other areas of your house, then the cause of the problem could be your hot water heater. A bad hot water heater can prevent hot water from flowing through the home or not produce hot water at all.

    Perform A Quick Flush

    Before you shut off the water, connect a garden hose to the drain valve and try and flush the water heater tank a bit while the water pressure is on.

If quite a bit of sediment comes out, you can repeat this a couple of times.
