Why Toilet Not Flushing

Jump to Section

Your toilet is one of the most important fixtures in your home, though many people don’t pay much attention to them until it doesn't work correctly. A weak flushing valve or flushing valve not working completely can cause your toilet to not flush properly. This could also because of a clogged toilet with poop, but you can learn more about it to deal with it properly.

A toilet that isn't flushing could lead to a number of problems, from overflowing toilets to water damage in your home. While there are a number of things that can go wrong with your toilet, a weak flushing valve is one of the most common problems. Usually a toilet can stop functioning due to a bad clog but you can easily learn how to unclog toilet when nothing works to deal with this.

However, if you have a toilet that isn't flushing properly, there are a few things you can do to try and fix the problem yourself. But first, let's look at the reasons why your toilet might not be flushing.

Insufficient Water in the Toilet Tank

If your toilet tank's water level is too low, it won't be able to flush properly. This can be caused by a few different things, such as a leak in the fill valve or a problem with the float arm. This can also be caused by a leak in the supply line or a problem with the fill valve. If you think this might be the problem, try adding more water to the tank and see if that fixes the issue. A lot of water is needed in order to have the best flushing toilet.

Sometimes it's as basic as twisting the flush valve. If your toilet's water intake valve was bumped, it might not be getting the water it needs to flush. In some cases, the float ball might have been adjusted improperly, causing it to sink too low and signal the tank is full before it really is. The root cause of this might also be the water pressure problems, pipe leaks, or other problems that require a plumber.

A low water level inside the toilet also means a low water level at the bottom of the toilet bowl. This is because there's a small tube known as a refill tube, connecting the fill valve to the overflow valve. As the fill valve fills the tank with water, the refill tube sends a small amount of water down the bowl via the overflow tube.

If you have a float ball, check where the float arm connects to the fill valve, and use a screwdriver to slowly turn the screw clockwise until the water level is about half an inch below the top of the overflow tube. Also, make sure you know how to adjust the water level in the toilet bowl and tank or call a professional to help you out.

Toilet Water Won't Flush Because of a Flapper or Fill Valve Problem

If the flapper valve isn't opening all the way or the fill valve is leaking, water will slowly drain from the tank. As a result, there won't be enough water to properly flush the toilet. A running toilet is an issue because it can waste a lot of water. And the reason for this is that your flapper seal is bent or cracked.

When you remove the toilet's tank lid, you'll see a chain attached to the flushing lever, and the other end of the chain is attached to a flapper valve. When you depress the lever, the chain lifts the toilet flapper allowing the water in the tank to rush into the bowl.

A flapper chain can slip from its hook, and the toilet won't flush if the chain is disconnected. In case you face, just hook the chain into the position. Make sure there's not too much slack in the lift chain. Flapper chains should have only about half an inch of slack.

Flappers can degrade, and a broken, warped, or deteriorated flapper cannot maintain a proper seal. Purchase a replacement at a local hardware store. A leaking flapper can also cause your fill valve to run. So, if you have a running toilet, check both your flapper valve and your fill valve.

Another potential problem is hard water build-up inside your fill valve, which can keep it from shutting off correctly. You can easily flush the fill valve yourself or get help from a professional plumber if you're not DIY savvy, and want to be safe.

Clogged Toilet

Sometimes, the problem isn't the toilet itself. The issue might be a clog inside the toilet. Toilets are only designed to handle certain types and amounts of waste. It can be easy to get clogged with items like sanitary products, a toy your kid dropped on the bowl, or a large amount of toilet paper.

If you have a toilet clog, you would obviously know. You can easily deal with small clogs by plunging them or poking them with a toilet brush to get things moving again. For stubborn clogs, you or your licensed plumber may need to use a toilet auger to get in there and unclog the toilet. To avoid all the hassle, go for the best small toilets available in the market if you don’t want to deal with toilet repairs all the time.

Clogged Siphon Jet and Rim Holes

When you pull the toilet flush handle down, the lift chain lifts the flapper out of the flush valve opening, allowing water to flow down to the bowl. Water enters the bowl through the siphon jet and rim holes. A Siphon jet is a hole at the bottom of the toilet bowl straight opposite the drain opening.

Rim holes are tiny holes located around the rim of your toilet bowl. Their purpose is to help guide water from the tank into the bowl when you flush. In toilets, siphon jets and rim holes are used to rinse the bow, but those without siphon jets use water from these holes for flushing. If these get clogged with mineral deposits or other debris, it can cause your toilet not to flush properly.

The fix for this is to check, insert and remove a piece of wire into each hole, as the wire may dislodge the blockage and take care of the issue. If necessary, you can add some white vinegar to the toilet tank or clean the holes with a toilet designed specifically to remove mineral deposits.

Loose Chain on the Flush Handle

If your toilet flushes fine occasionally but not others, there may be something wrong with the chain that connects the flush handle to the flapper. This chain is what lifts the flapper when you flush, allowing water to exit the tank and enter the bowl.

If this chain is too long, it can become tangled and prevent the flapper from opening. Conversely, if the chain is too short, it can come off entirely. In either case, simply readjusting the chain so that it is the correct length should fix the problem.
