Why the Tank Isn’t Filling

It could happen to everyone at one time or another. We flush the toilet and find ourselves staring into an empty tank. If you’re tired of your toilet tank being empty when you need it most. it’s time to fix the problem once and for all. Here are five possible causes of this irritating problem, as well as tips on how to deal with each one.


Sometimes, a toilet float is adjusted too high so that not enough water will enter the tank to flush waste away. To resolve, adjust your toilet float to its lowest possible position. If you don’t know how to do it, contact a plumber as these instructions could vary depending on your toilet model. In addition, if your toilet has been used for some time without any issues and suddenly begins to have problems.

 chances are good that you need to replace your toilet flapper or fill valve. For example, if replacing parts doesn’t solve an issue of no-flush after several attempts at repair or adjustment of floats and other components in the tank system have failed. Then chances are good that a replacement is necessary. The flapper (also called a flush valve) might be stuck open or closed or broken altogether.


First, check to see if your toilet’s fill valve needs to be replaced. The valve may be worn out, or it may not shut properly. If replacing a component doesn’t solve your problem, try adjusting it until you get it to work correctly. If that doesn’t help either, it’s probably time for a new toilet (or at least a new tank). To replace an old fill valve with a new one: Shut off the water supply to your toilet.

The water level will drop as you flush

The toilet tank has a fill valve at its base that sends water into it. The water level in your tank should gradually drop as you flush. This is normal, and it helps with the aeration of the noise you hear after flushing. If your tank refills too slowly or doesn’t refill at all. However, there may be a problem with either the fill valve or another part of your plumbing system. Let’s take a look at what might be going on under that bowl.

The float arm may need replacing

You can usually see if a float arm is causing problems by looking in your toilet tank. It should be directly over, or slightly under, an overflow tube (refer to Figure 1). If you can’t see a float armor it doesn’t appear to be level with these reference points. You may need to replace it. If there is no visible float arm inside your tank. Then you have a ballcock style fill valve and will need to replace that instead. Check out our guide on how to fix a toilet.

The lever that controls your flapper might not be working: The chain connecting your flapper to your lever may have broken, meaning that when you flush, nothing happens. To test whether this is the case, lift on the flapper while someone else flushes. If water begins filling up your bowl again as soon as you release pressure from above. Then it’s likely that your chain has snapped. Unfortunately, there isn’t much else you can do besides replacing both parts.

The water level will drop when the toilet is being used

This is the purest one, but its value points out. When you flush your toilet, water will drain out of it into your toilet tank. This can be observed by looking at how much water is in your toilet bowl after flushing. If you’re still on city water and not connected to a well or other type of private supply. Then if your toilet is flushing normally there should always be a certain amount of water in your toilet bowl. No matter how long you let it run.

If your toilet isn’t filling up with water after you flush, then something may be wrong with your toilet fill valve. (or even worse, something may have broken inside your toilet). It could also mean that there is a leak somewhere else in your home that is draining off all of your water. The only way to tell for sure what’s going on would be to contact a plumber.

The tank needs to be cleaned out

What’s happening? Simply put, gunk is building up in your tank. When you use a toilet, after each flush a little bit of leftover waste will remain in your bowl. It settles at the bottom, and over time it builds up and can cause trouble for your toilet and other areas as well. If there is too much stuff sitting at the bottom of your tank when you flush water through it to refill. You may get only partial or incomplete flushes. This not only wastes water but also makes your toilet run longer than necessary.

The good news is that cleaning out your tank every once in a while should do away with these issues. We recommend doing so every 6 months or so. You don’t need any special tools just a regular old toilet brush (and some elbow grease). Just follow these steps:

 1) Turn off the water supply to your toilet (located underneath).

2) Remove both lids from your tank.

3) Use your brush to clean out all debris from inside both lids and inside of your tank itself.

 4) Flush several times until no more debris comes out of either lid opening.

5) Put everything back together and turn on your water supply. That’s it! Your toilet should be working like new again.


Toilet tanks that do not fill up can be caused by one of two things. A problem with your flapper or a problem with your ballcock. While each of these mechanisms is unique. There are some steps you can take to repair and maintain them to prevent future malfunctions. Make sure that your flapper is tightly fastened. While also making sure that your chain is attached securely and that it connects properly to the float. You should also make sure that your water supply lines are intact and leak-free. If all else fails, contact a plumber for professional assistance.
