Why Is There No Water in My Toilet Tank? 

Did you just try to flush your toilet, and nothing changed? Peek within the tank, and you might see no water inside. Before you panic, rest easy that fixing this issue is usually simple. If you can’t figure it out yourself, you can always arrange toilet repair with an Expert plumber. Follow these tips to diagnose and repair the problem of no water in the toilet tank. 

Check the Water Supply 

The first move is to verify that the water is running. If you or someone in your household recently completed a toilet repair, you probably turned off the water first. Did you not realize you had to turn it back on? To check, turn the water shut-off valve on the wall behind the toilet. If the valve was closed, water will now start refilling the tank. If this does not work, turn on the water at your sink or another plumbing fixture. If nothing spills out from the tap, you could have a bigger water supply issue. Contact your water company to find out more. 

Reposition or Replace the Float Mechanism 

Older toilet designs use a float ball to measure the water level as it goes up in the tank. When the ball hits a specified height, the float arm it’s joined to stops the water flow. However, insufficient water could enter the tank if the ball is positioned improperly or the arm is broken. To adjust the float ball, start by removing the toilet tank cover. Bend the float arm up slightly to alter where it sits in the tank. If this does not fix the problem, you may need to replace the full float mechanism. You should be able to complete this yourself by following the directions that come with the replacement parts, or you can work with a plumber for help. Just realize that float balls are old toilet design. You may appreciate improved durability and efficiency if you upgrade the existing tank components or replace the toilet entirely. 

Adjust the Fill Valve 

Modern toilets utilize a float cup rather than a float ball, coupled with a fill valve and water level rod. There may very well be no water in the toilet tank because the valve has slipped out of place or become clogged. Here are techniques to consider: 

  • Test the fill valve: Have a look inside the toilet and find the fill valve on top of a vertical tube device on the left side of the tank. Make sure it’s secure and evenly attached to the tube. Then, change the water level. Current models of toilets have an adjustment knob you can turn by hand, while older designs may require you to loosen an adjustment screw with a flathead screwdriver. Flush the toilet and allow the tank refill to test the water level. Adjust it until the water comes to {about|approximately|roughly]] one inch below the top of the overflow tube. 
  • Clean the fill valve: Mineral buildup and other gunk might be blocking the valve and preventing your toilet from filling. Turn off the water behind the toilet and take away the fill cap. Then, steadily turn the water back on, cupping your hand over the valve to prevent water from spraying all over. After several seconds, turn the water back off. Finally, clean off the fill cap to clear away hard water buildup. If the cap is cracked, replace it. 
  • Clean the valve tube: The tube below the fill valve could also be plugged. Shut off the water and remove the valve hardware. Then, stick a slim bottle brush or wire down the tube. Turn the water back on just a little to flush away the blockage. Replace the valve hardware and flush the toilet to check your work. 

Repair or Replace the Trip Assembly 

If you’ve followed the steps above without positive results, the final possibility is a damaged trip assembly. This element connects the flush handle to the tank. If it’s broken or positioned poorly, the flush cycle may not complete, leaving the tank bone dry. Remove the toilet tank lid and examine the trip assembly attached to the handle. If it’s out of place, reposition it. If the assembly is bent, worn or broken, change it out. Whether you complete the job yourself or leave it to a plumber, this uncomplicated repair should get your toilet tank filled with water once again.
