When your toilet tank is not filling with water, it can be frustrating. In some cases, the tank may not be filling up with water entirely, or it may take several flushes to clear the bowl. Either way, there are several fixes you can do yourself to remedy this problem. In most cases, you can fix the issue without having to contact an emergency plumber in Houston.
If your toilet tank is not filling with water, the most likely culprit is the float ball. The float ball sits above the water in the tank and when the optimal water height is reached, it stops the water from coming in by blocking the water flow. If the float ball is too low, it will limit the amount of water that can flow into the toilet tank.
To fix the issue, you should move the float arm to a slight upward bend, so the ball floats higher and allows the entry of more water. However, if this does not fix the water level issue, you may need to replace the float ball entirely.
If the toilet tank is still not filling with water, the problem may be the fill valve. The fill valve controls how much water enters to refill the tank from the supply line. If your toilet’s fill valve has a float arm, you should first remove the toilet cap lid and find the fill valve on the left side.
Then, you should use a flat-head screwdriver to adjust the screw, turning it clockwise to raise the fill valve. This will allow more water to enter the tank. You can then flush the toilet after the adjustments to see if this fixed the water level issue.
Alternatively, if your take has adjusted cylinders, you should still remove the toilet lid and find the fill valve on the left side. You should then pinch the float clip on the float valve and slide it up to let more water in.
Another reason the tank may not be filling is that the fill valve may be blocked. First, shut off the water supply, then you should remove the cap from the fill valve in the tank. Next, you should turn on the water using a small plastic bowl over the opening to redirect the water down into the tank. If no water is coming out of the opening with all parts of the fill valve removed, there is a clog in the line.
You will then want to shut the water off again and remove the supply like from the bottom of the toilet. The supply line should then be redirected into a small bowl and the valve turned back on. Removing all water out of the supply tube is important; otherwise you will have to shut the water off from the house and remove the valve from the wall, as the blockage is in the inlet of the valve.
If the blockage is not in the valve, you will then have to remove section back to the meter until the blockage is found.
The problem could also lie in the trip assembly, which is part of the flash handle connected to the tank itself. The assembly may be improperly positioned, or it may block itself when the lid is on. This would cause the flush to not be completed as intended.
To inspect the trip assembly, you should open the lid and see if it is bent, broken, or worn out. If it is, you should then consider replacing the trip assembly to fix the water level problem.
The toilet tank not filling, could also be from coming from outside the toilet. One issue may be the water pressure itself. Low water pressure can cause the tank to not fill properly. This issue can come from old pipes or leaking pipes that do not have the flow strength to reach your house.
