How to Fix a Toilet Bowl Not Filling With Water After Flushing

Your toilet is arguably one of the most important features of your home. But toilets tend to be taken for granted. That is until something goes wrong.

One of the most common complaints we get from homeowners is that their toilet bowl is not filling with water after flushing. If you’re experiencing this issue, you’re in luck (well, sort of). There are four common causes of this issue, and you don’t need to be an experienced plumber to fix it.

4 Reasons Your Toilet Bowl Won’t Fill With Water After Flushing

1. The Float Ball Needs to Be Adjusted

The Problem

This is the most common culprit of toilet bowls that won’t fill with water. The float ball sits above the water in the toilet tank. When the water reaches its optimal level, the float ball is supposed to stop the incoming flow of water by moving the float arm to block more water from entering.

If the float ball is too low, it may not allow enough water into the tank.

The Solution

Simply adjust the float arm by slightly bending it upward. This will make the float ball rest higher and allow more water into the bowl. If this doesn’t fix the issue, the float ball may need to be replaced.

2. There Is Low Water Pressure

The Problem

Sometimes, this issue is not caused by the toilet at all. If the water pressure in your home is low, it can prevent the toilet bowl from filling properly. Low water pressure can be caused by numerous things such as old or leaking pipes.

The Solution

If you suspect you have low water pressure, we recommend scheduling an appointment with a plumbing professional. They will be able to quickly and efficiently determine if you have low water pressure and find the underlying cause.

3. The Trip Assembly Is Bad

The Problem

The trip assembly is part of the flush handle that connects to the tank. If the trip assembly is poorly positioned, it can become blocked when the lid is on. This can cause the flush cycle to malfunction, resulting in a tank that does not fill as it should.

The Solution

If you suspect the trip assembly is bad, remove the lid and inspect it. If you notice the trip assembling is broken, bent, or worn out, it’s time to replace it.

4. The Fill Valve Needs an Adjustment

The Problem

The flow of water from the supply line to refill the toilet tank is controlled by the fill valve. If the fill valve isn’t properly placed, the water supply can be impeded.

The Solution

Locate the fill valve in the toilet tank. It will likely be on the left side. Using a flathead screwdriver, turn the adjustment screw clockwise. This should raise the fill valve and allow more water to flow into the tank. On the contrary, if you need less water in the tank, turn the screw counterclockwise to drain.

Once you have collected the right amount of water, flush the toilet to see if the water fills properly.
