Why Is There No Water in My Toilet Tank? 

Did you just try to flush your toilet, and nothing happened? Glance inside the tank, and you may see no water inside. Before you panic, rest assured that fixing this problem is usually straightforward. If you can’t figure it out yourself, you can always schedule toilet repair with an experienced plumber. Follow these tips to diagnose and repair the problem of no water in the toilet tank. 

Check the Water Supply 

The first step is to make sure the water is turned on. If you or someone in your household recently performed a toilet repair, you probably turned off the water first. Did you forget to turn it back on? To find out, turn the water shut-off valve on the wall behind the toilet. If the valve was closed, water should now start refilling the tank. If this doesn’t work, check the water at your sink or another plumbing fixture. If nothing flows from the tap, you could have a bigger water supply issue. Call your water company to learn more. 

Reposition or Replace the Float Mechanism 

Older toilet models use a float ball to measure the water level as it rises in the tank. When the ball reaches a certain height, the float arm it’s connected to stops the water flow. However, insufficient water may enter the tank if the ball is positioned incorrectly or the arm is broken. To adjust the float ball, start by removing the toilet tank lid. Bend the float arm up slightly to alter where it sits in the tank. If this doesn’t fix the problem, you may need to replace the entire float mechanism. You should be able to do this yourself by following the instructions that come with the replacement parts, or you can hire a plumber for help. Just note that float balls are old toilet technology. You may enjoy improved reliability and efficiency if you upgrade the existing tank components or replace the toilet altogether. 

Adjust the Fill Valve 

Newer toilets use a float cup instead of a float ball, coupled with a fill valve and water level rod. There may be no water in the toilet tank because the valve has slipped out of place or become clogged. Here are some to try: 

• Adjust the fill valve: Look inside the toilet and locate 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, adjust the water level. Newer toilets have an adjustment knob you can turn by hand, while older models may require you to loosen an adjustment screw with a flathead screwdriver. Flush the toilet and let the tank refill to test the water level. Adjust it until the water comes to about may be clogging the valve and preventing your toilet from filling. Shut off the water behind the toilet and remove the fill cap. Then, gradually turn the water back on, cupping your hand over the valve to prevent water from spraying everywhere. After several seconds, turn the water back off. Finally, scrub the fill cap to remove hard water buildup. If the cap is cracked, replace it. 
• Clean the valve tube: The tube below the fill valve could also be clogged. Shut off the water and remove the valve hardware. Then, insert a slim bottle brush or wire down the tube. Turn the water back on slightly to flush away the debris. Replace the valve hardware and flush the toilet to test your work. 

Repair or Replace the Trip Assembly 

If you’ve tried the steps above without success, the final possibility is a damaged trip assembly. This component attaches the flush handle to the tank. If it’s broken or positioned poorly, the flush cycle may not complete, leaving the tank empty. Remove the toilet tank lid and check the trip assembly attached to the handle. If it’s out of place, reposition it. If the assembly is bent, worn or broken, replace it. Whether you complete the job yourself or leave it to a plumber, this easy repair should get your toilet tank filled with water once more.
