If you just flushed the toilet and it wouldn’t flush, you’re definitely searching for an easy way to address this frustrating problem. We have built this detailed guide to addresses the key factors that sometimes lead the toilet to not flush and the normal remedies to this issue.
Trying to find out why a toilet flushes incorrectly may be confusing if you don’t know which part is malfunctioning or either it’s due to a clog or any third-party element. That’s why we’ll share the most common causes toilets start having problems flushing and how to repair them yourself. “Toilet won’t flush” is a typical issue that often occurs in many households, but in most cases, it can be easily dealt with.
The most popular explanation why toilets won’t flush is because of clogs, there is not enough water, the flapper is damaged, blocked inlet holes, and even issues with the chain.
Reason #1: A Clogged Toilet
That goes without saying, a clogged toilet is something that everybody has to contend with. Typically, clogged toilets arise as a consequence of flushing anything that should not be flushed, using too much low-quality toilet paper, or large stools in the toilet. This condition may also be induced by sanitary and feminine goods such as tampons and should usually not be flushed.
Solution: Use a Plunger
It is a popular issue which thankfully has a common remedy, the plunger. If you use a plunger and force it as strongly as you can you should be able to clear the clog in the toilet and achieve improved efficiency when flushing. If nothing works, such equipment as a plumbing snake will come in handy.
Reason #2: Inaccurate Water Level In The Tank
In order to flush with efficiency, the toilet requires the correct volume of water in the reservoir. If the amount is too low or too high, you can face trouble with the toilet when you flush. Often the toilet manufacturer places a marking within the tank, letting you exactly how many gallons of water to put in for the correct working of your toilet. There could have been a manual modification of the water level to conserve water or misalignment of parts inside the tank.
Solution: Adjust The Level
When the toilet tank fills, there is a float inside that controls the toilet water volume, in order to prevent water overflow or water insufficiency inside the tank. The float may be a rubber ball-type component. Anyway, the water levels inside the tank must be adjusted using a screw-like device located at the top of the fill valve. If rotated to the left, it will elevate the float and will enable it to accept some more volumes of water into the tank.
Reason #3: Trouble with the Flapper
The flapper is a cool little instrument that sits connected to a chain in the toilet tank that causes the appropriate volume of water to stream out when the toilet is flushed. When the lever is flushed, the flapper opens to allow water to escape and then shuts to avoid additional water from running. If the flapper appears to be damaged, bent, or broken, it might be the cause why your toilet doesn’t flush properly.
Solution: Replace Flapper
If the flapper is damaged in a manner that prohibits it from functioning correctly, it would have to be replaced. A replacement flapper is readily accessible at local hardware shops and is relatively inexpensive. Drain the tank full prior to removing the flapper, and then connect the new flapper to the chain.
Reason #4: Blocked Inlet Holes
Inlet holes are the tiny holes found underneath the upper edges of the toilet bowl. When the toilet is flushed, water rushes out of these holes. When one of these openings is plugged or blocked, the toilet does not flush with maximum power. This issue can be detected by observing these holes as the toilet flushes and make sure the water comes out of all of them.
Solution: Unclog Inlet Holes
It can be done yourself, but a little effort would be required. If you’re up to the challenge, you might consider using a funnel or water spray bottle to splash heated vinegar on the clogged inlet holes. You may use a mirror to look underneath the edges of the rim. Let it stay overnight. Meanwhile, you can also scrub the area using under-the-rim toilet brushes and try using a tool such as a simple paper clip, twisted hanger, or old toothbrush. A video with directions is here.
Reason #5: Flapper Chain Issues
If your bathroom isn’t flushing, it may be an issue with the lift chain of the toilet. The chain is connected to the flapper and raises it to allow water to come in and out. Perhaps this chain is rusted, damaged, or installed at the wrong length. If either of these issues happens the chain would not raise the flapper correctly to enable the water to drain out to the toilet.
Solution: Adjust or Replace The Chain
There may be problems with the chain being too small, which would allow the toilet to not function. If it’s the problem, easily adjust the chain’s length. If the chain appears to be bent or rusted to a point that it does not function, it would have to be replaced. A replacement chain may be bought at the hardware store.
Often note, if all of these things appear to be too large to cope with or if they don’t work, there may be a more complicated issue with your plumbing under the surface. In that case, get the help of a professional plumber.
