One of the most dreaded plumbing problems homeowners encounter is the clogged toilet. When your toilet is not flushing correctly, it’s undoubtedly a huge problem. These are obvious problems that require emergency plumbing repairs, but what about those problems that are not that obvious? 

For instance, your toilet may still flush, but it could be weak, or it doesn’t last as long as it’s supposed to. This leads you to do multiple flushes. This problem might seem minor to you, but it can quickly escalate to a costly repair if you don’t act on it early on. 

To give you an idea of what you should be looking out for, here are some reasons your toilet is flushing weak and how you can address them:

1. Not Enough Water in the Tank Causing a Weak Flush

When you flush, you are releasing water from the tank into the toilet bowl. This generates a suction that results in the flushing of the toilet. However, when the amount of water in the tank is not enough, it can’t release the amount needed to flush properly. This is why you notice a weak flush or the toilet might not flush at all. 

Quick Fix

Open your toilet tank and check if there’s a mark inside indicating how much water should be in the tank. If there’s no such mark, measure an inch beneath the overflow tube. After flushing, check if the water rises to that level. If it doesn’t, you should make some adjustments. 

Most toilets have a water intake assembly inside a tank or a float, or a small round ball that is directly connected to the valve. This fill valve stops filling the tank when the water reaches the float. What you can do is bend the float arm up to raise the water level. If what you have is an intake assembly, you only need to look for a metal clip on the assembly and move it up. 

2. Toilet Flapper or Lift Chain Problem Causing a Weak Flush

The rubber cup fixture you see at the bottom of your toilet tank is called a flapper, and it covers up the drain that leads to the bowl. The flapper is connected to the long metal arm by a lift chain. The metal arm is then connected to the toilet handle, and when you flush, the metal arm lifts the chain and the flapper, releasing water into the toilet. 

The chain determines the height of the flapper rise and the length of time it is left open. If the flapper is loose in any way, water can continuously leak into the bowl. Also, if the chain is detached from the flapper or it’s too long, the flapper won’t open as it should. 

Quick Fix

Flappers that are always malfunctioning will require a replacement. It’s a good thing both the flapper and the chain don’t cost a lot to replace, and they’re quite simple to work with. Just remember to turn off the water before you start replacing the flapper and the chain. 


At this point, you now know two of the possible issues you could encounter. These are not minor problems, and you can fix them with ease. Regular plumbing maintenance can also help you avoid these problems – one of the many reasons you should have your trusted plumbers check your toilet and plumbing system regularly.
