Why Is There No Water in My Toilet Tank?

Why Is There No Water in My Toilet Tank?

Your toilet tank is supposed to refill with water every time it is flushed. An empty toilet tank that does not refill after flushing is a sign of trouble and needs to be fixed as soon as possible to avoid inconveniences. At Mr. Rooter Plumbing, we get many service calls related to empty toilet tanks that won’t refill. With our experience and expertise in fixing a wide range of toilet problems, we’ve come to know a thing or two about empty toilet tanks.

The following are some of the possible reasons why your toilet tank might be empty and how the problem can be fixed.

Float Ball Needs to Be Replaced

Older-style toilets have a float ball inside the tank, which regulates the water level within the tank. Like other toilet components, the float ball can develop cracks or become worn out over time and fail to float properly. A faulty float may cause the water flow into the toilet tank to stop. If the float ball is worn, you’ll need to replace it with a new one. To replace the float ball, turn off the water to the supply line and remove the toilet lid. Then, follow the directions on the instruction manual that comes with your new float ball.

Float Ball Needs to be Adjusted

A misadjusted float ball is a common culprit for an empty toilet tank that won’t refill. If the float valve is too low in the tank, it may lead to too little water flowing into the tank, hence, you’ll have a toilet tank that never fills. A simple float ball adjustment might be all you need to fix the problem. To adjust the float ball, follow these steps:

  • Step 1: Lift the lid off the tank.
  • Step 2: Slide a finger beneath the float arm and bend it slightly upward to raise the ball to the correct level. The water should fill the tank after you’ve raised the float ball to the correct level.
  • Step 3: Flush the toilet and see how the float ball behaves.

Newer toilets are equipped with a fill valve instead of a float ball. The fill valve can slip out of place and result in a situation where the water does not fill the tank. To adjust the fill valve, use a flat-head screwdriver to twist the screw on the water level rod in a clockwise direction. This action will move the float cup up and allow water to enter the tank. Then, flush the toilet to see what happens. If the fill valve still doesn’t work after the adjustment, call a skillful plumber to help you with toilet repair.

Faulty Trip Assembly

Another common reason why your toilet tank might be empty is a broken or improperly positioned trip assembly. The trip assembly is the part inside the toilet tank that is connected to the flush handle. This assembly could be broken, bent, or positioned incorrectly, resulting in a toilet tank that won’t refill. Lift the lid off of the tank and inspect the trip assembly to see if it’s in good shape or positioned correctly. If the trip assembly is damaged, you need to replace it.
