Hello there, I'm a plumber with years of experience in fixing all sorts of bathroom issues. I've seen a lot of problems with toilet tanks not filling up, and I'm here to help you troubleshoot and hopefully resolve this issue.
There are several reasons why a toilet tank might not be filling up properly. I'll go through some of the most common causes and solutions:
1. Faulty Fill Valve: The fill valve is a crucial component that controls the water flow into the tank. If it's not functioning correctly, it won't be able to refill the tank after each flush. To check this, you'll need to first remove the toilet tank lid and locate the fill valve, which is typically on the left side of the tank. Look for signs of wear or damage, and ensure that it is not clogged with debris. If it's faulty, replacing it is often the best solution.
2. Blocked Fill Valve Inlet: Sometimes, the inlet of the fill valve can become blocked by debris or mineral buildup. This can prevent water from flowing into the tank. You can try cleaning the inlet with a small brush or a straightened paperclip to remove any obstructions.
3. Float Arm Issues: The float arm is connected to the fill valve and is responsible for controlling the water level in the tank. If the float arm is stuck or not set at the correct height, it can prevent the tank from filling up. Check the float arm for any signs of damage or obstruction, and adjust its position if necessary.
4. Float Adjustment: The float controls the water level in the tank. If it's not set correctly, the tank may not fill to the proper level. You can adjust the float by bending the arm or adjusting the clip that holds it in place.
5. Water Supply Line Problems: If there's an issue with the water supply line connected to the fill valve, it might not be able to deliver the necessary water pressure to fill the tank. Check for kinks, leaks, or other issues in the supply line.
6. Shutoff Valve Issues: The shutoff valve that controls the water supply to the toilet can sometimes be partially closed, reducing the water flow to the fill valve. Make sure the shutoff valve is fully open.
7.
Wax Ring Condition: Although it's less common, a damaged or leaking wax ring can affect the water flow to the toilet, as it can create a vacuum seal that prevents water from entering the tank. Inspect the wax ring for any signs of damage.
8.
Pressure Issues: If the water pressure in your home is too low, it might not be sufficient to fill the toilet tank properly. You may need to consult with a professional to check the water pressure and possibly install a booster pump.
9.
Cistern Cracks or Leaks: Lastly, check for any cracks or leaks in the toilet tank or bowl. These can cause water to escape and prevent the tank from filling up.
To fix the issue, you'll need to systematically go through these potential problems and address them one by one. Start by inspecting the fill valve and the float arm, as these are the most common culprits. If you're not comfortable doing this yourself, it's always best to call a professional plumber to avoid any potential damage or further issues.
Remember, regular maintenance and inspection of your toilet can help prevent these types of problems and keep your bathroom functioning smoothly.

Toilet fill valves control the flow of water from the supply line to refill the tank between flushes. If your toilet's fill valves use float arms, then the fix is to start by removing the toilet cap lid and locate the fill valve in the tank, it should be on the left side.
