There is nothing worse than experiencing plumbing issues in your home. One issue which is extremely common is a slow-filling toilet tank. Whilst it might not seem like a serious problem, it’s important to get it sorted out as soon as possible. In this article we explain the different reasons why your toilet is slow to fill as well as share expert tips to repair your toilet.

What causes the toilet tank to fill very slowly?

If your toilet bowl is filling slowly, it is most likely due to a valve problem. More often than not, the toilet fill valves get clogged with some form of debris. Another common reason your valve might be experiencing problems is if your toilet has not been used in a while.

Most toilet bowls which are running on a regular water pressure system fill up in under a minute. Therefore, if you are noticing that it takes more than a minute for your toilet bowl to fill up, it indicates that there is a problem somewhere.

Why is your toilet slow to fill?

Although a toilet fill valve that is experiencing problems is usually the most common issue that causes your toilet bowl to be slow to fill, it is by no means the only issue.

Here is a list of the different problems that could be causing your toilet bowl to fill slowly:

Clogged vent

A clogged vent is a common plumbing issue, which could be the source of your slow filling toilet bowl issue. In order for the water flow to run smoothly through pipes, it needs a source of air, otherwise a vacuum is created and the flow of water is compromised. If your vent is clogged, it means that these pockets of air are not being let in and your pipes are therefore not allowing the water supply to move through.

You can easily identify whether or not your toilet vent is blocked by removing the cover on the roof. If you can see obvious debris that is blocking the vent, you will know that a blocked vent is causing your problem. As the opening to your vent is on your roof, you might need a professional to come out and look at it for safety reasons.

Clogged drain

Clogging is another common plumbing issue. A clogged drain usually happens when you use too much toilet paper, or you have flush something down the toilet that you shouldn’t have, which can create additional problems with the flush handle. These things get stuck in the drain and prevent the water supply from freely moving.

There are a few different signs of a clogged drain. Whilst it might cause your toilet bowl to start filling up slowly, you might also notice that your toilet won’t let anything go down the pipes. When you flush the toilet, you might notice everything backs up and the toilet water rises in the toilet bowl.

Faulty valves

Valves are another common source of issues with toilet bowls. Components such as the water supply valve and the flapper valve are important for the overall functioning of your toilet system, so if either of them are not working, you will experience problems. Whilst both of these valves can break, which will prevent your toilet bowl filling properly, they might also cease to do their job if they are blocked, so it is important to check them if you think something is wrong.

Waterlogged float ball

The float ball is a small device that is placed in the toilet tank, but it is extremely important because it regulates the amount of water that goes into the toilet bowl. Essentially, the float ball or float cup floats on the surface of the water on the tank and controls how much water is entering the tank. If it is not functioning properly, the correct amount of water will not be present in the tank. Essentially it disrupts the water level in all areas of your toilet.

This problem is easy to fix because all you need to do is take the old ball out, disconnecting it from the float arm and replace it with a new one. However, the float ball is old plumbing technology, so if you run into problems with it, it is best to take this opportunity to update your toilet’s interior mechanisms to make them more efficient.

Plumbing issues

If there is no obvious issue that you can detect, it might mean that there is a more serious plumbing problem, in which case you will need more intensive water line repairs. Things such as leaks or blockages further in your piping system can cause your toilet bowl to struggle filling up. If this is the case, you will have to contact a plumber to come and detect what the problem is and fix it.

Tips to repair a slow filling toilet tank

Luckily, most of the time, it is fairly easy to fix a slow filling toilet tank. However, if you are ever in doubt about any step of the process, you should contact a professional plumber. If you think you are confident enough to face the issue yourself, below are some expert tips to walk you through what you should do.

Firstly, it is important to remember that how you fix the toilet will depend on what the problem is, so you first need to identify the source of your problem. Once you have identified the problem, you then need to determine the appropriate solution, which will be different in each situation. By the end of your fix, the water in your toilet’s tank should be an inch below the overflow tube.

Make sure to check all the areas of your toilet that are easily accessible (float ball, valves, etc.). Most of these problems are easily fixed and just involve replacing an item or removing blockages. If the valve is misplaced, you might have to realign it to the left side of the tank where the tailpiece attaches to the supply tube.

If you find that blockages are the issue, it is beneficial to completely clean out the area with something like a bottle brush. That way, you avoid any further buildup of debris. Outside of these issues, anything else can be more difficult to fix so we recommend calling a licensed plumber to take a look at your plumbing system.
