Is your toilet water slow to refill after each flush? You’re not the only one experiencing this problem. Slow-filling toilets are a common problem among homeowners. However, it is possible to solve them. This issue could be caused by a variety of reasons. Although none of these issues are serious or costly, it is possible to identify the problem and find the right solution to make the toilet work again as quickly as possible.

This blog will explain the three most common causes of slow-filling toilets, as well as how to diagnose the problem and what steps you can take.

There are three possible reasons why a slow-filling toilet may occur

A toilet tank should usually fill in within one minute, depending on how hot the water is. You may need to address the problem if it takes longer than that. These are the possible causes of slow water filling in your toilet.

Water Supply Valve Problem

The water supply valve is located just below the toilet tank. It controls the flow of water into the tank. It may not deliver the right amount of water at the appropriate speed if it is partially closed or malfunctioning. Another issue that could be a problem is a buildup or obstruction of water flow. This can slow down the valve’s filling speed.

Troubleshooting tip Make sure the valve is fully open. Contact a licensed Long Beach Plumber if the valve doesn’t produce enough water to fill the tank.

Waterlogged Float ball

The float ball is placed on top of the tank to control the flow of water. This helps prevent overflows. The float ball can become clogged and will prevent the tank from filling efficiently. It can also prevent water from reaching the tank in the right amount, or cause the tank to fill slower than desired.

Troubleshooting tip Take off the lid of the toilet tank and check the water level. You may have a float ball that isn’t floating close to the top of your tank or it is only partially filled. It’s not difficult to replace the float ball. It is as simple as removing the old float ball from the float arm, and replacing it with the new one. A float ball is an old type of toilet technology. Consider replacing the inner parts of your toilet with modern ones if this is happening.

Fill Valve Tube Issues

The fill valve attaches to the vertical tube-shaped device within the toilet tank. The tank’s water level is controlled by the fill valve. Fill valves can become worn down over time, clogged or out of alignment. These issues could prevent your toilet from filling up with water correctly.

Troubleshooting tip Once you have determined that the problem is not with the water supply valve, or a float ball that has become clogged up, it’s time for you to look at the fill valve. Check the fill valve for wear or improper positioning. The tank should have it mounted on the left-hand side. A tailpiece extends through the tank’s bottom, where it connects to the shut-off valve and supply tube.

How to fix a slow-firing toilet

Here are some steps to take to correct the issue.

Turn on the water supply valve.

Sometimes, the water supply valve may only be partially open. To make sure the valve is fully open, check it. Step two should be taken if the water valve has not yet opened.

Adjust the fill valve

These steps will allow you to adjust the fill valve.

  • Take off the tank lid to locate the fill valve. It’s usually located on the left side.
  • You must ensure that the fill valve is properly and securely attached to the tube.
  • To let more water in the tank, you can use an older toilet to loosen the adjustment screws with a flathead screwdriver.
  • To add more water to a toilet with a newer model, adjust the fill valve adjustment knob by turning your hand.
  • All toilets should have water levels at least an inch below the top end of the overflow tube.
  • After flushing the toilet, check that the tank is filled at the correct rate and contains enough water.

Clean the fill valve

Are you seeing mineral buildup on the valve or gunk? Here are some tips to clean it.

  • Turn off the water supply to the toilet and take out the tank lid.
  • Take off the screws at the top of the fill valve.
  • Slowly turn on water supply. To prevent being sprayed, place your hand above the valve.
  • Allow the water to flow freely through the valve. This will flush out any debris or buildup.
  • After a few seconds, turn off the water supply.
  • Flip the fill cap to reveal the washer. Use a screwdriver to remove the washer and clean away any mineral buildup.
  • Replace the fill valve if you see cracks.
  • Replace the valve and secure it with the screws. Turn on the water to check if the problem has been resolved.

Replace or fix a waterlogged floating ball

  • You should check to make sure the tank is not too low on the float arm and float ball. If this is the case, raise the arm so that the ball is higher in the tank. This will allow more water to flow into the tank.
  • If that fails, and you think the float balls are the problem, you might need to replace them or talk to your local plumber to upgrade to a more modern style.

Repair a problem with a valve tube

You must clear out any debris from the valve tube in order to fix it.

  • Start by turning off the water supply.
  • Take out the hardware.
  • To clean the tube, use a bottle brush or a thin wire.
  • To flush out any residue or to clear all clogs, open and close the water supply valve several times.
  • Check to make sure the toilet is properly flushed after you have replaced the hardware and tube.

Install a replacement tube if the tube is damaged or has any holes or tears. If your toilet fills slowly due to a broken or buildup pipe, we recommend calling a local Long Beach Plumber to resolve the problem.
