Toilet Not Flushing Properly? Here’s How to Fix It

Is your toilet not flushing properly? Don’t worry, you’re not alone. Many Logan residents face this common plumbing issue, and it can be a real pain in the bum. In this blog post, we’ll explore the reasons why your toilet might not be flushing correctly and provide you with practical solutions to get your loo back in working order. So, let’s dive in and tackle this toilet trouble head-on!

Common Reasons Why Your Toilet Is Not Flushing Properly

Before we get into the nitty-gritty of fixing a toilet that won’t flush, it’s essential to understand the reason your toilet won’t flush. Here are some of the most frequent culprits:

Blockage in the Toilet Bowl or Drain Pipe

One of the most frequent reasons why a toilet isn’t flushing well is a blockage. This can be caused by excessive toilet paper, foreign objects, or even a build-up of mineral deposits. A clogged toilet or blocked toilet drain pipe can significantly impede water flow, resulting in an incomplete flush where the water rises in the bowl and then slowly drains. 

DIY Tips to Fix a Blockage

If you suspect a blocked drain is causing your toilet’s flushing problem, here’s what you can do:

1. Use a toilet plunger: This is often the quickest and easiest way to clear a minor blockage. Make sure there’s enough water in the bowl to cover the plunger head, then plunge vigorously for about 20-30 seconds.

2. Try a toilet auger: If the plunger doesn’t work, a toilet auger (also known as a plumber’s snake) can help clear more stubborn blockages further down the drain pipe.

3. Use hot water and dishwashing liquid: Pour a bucket of hot (not boiling) water mixed with a squirt of dishwashing liquid into the bowl. Let it sit for a few minutes, then flush to see if the blockage clears.

4. Call a plumber: If these methods don’t work, it’s time to call in our Logan plumbers to tackle the problem.

Faulty Flush Mechanism

The flush mechanism inside the toilet tank is responsible for releasing water into the bowl when you press the button. If any part of this mechanism is damaged or worn out, it can lead to flushing problems.

Before purchasing toilet flush valves, it’s important to do your research to ensure the right fit for your toilet. Standard valves, featuring a two-inch valve and flapper, are commonly found in most older toilets, whether they have large tanks or are low-flow. For improved performance, consider upgrading to a three-inch flush valve, known for better flushes with reduced water usage.

The tower-style valve follows, allowing unrestricted water flow for faster flushing. The four-inch flush valve uses a piston, enabling a 360-degree release and the fastest flush with minimal water usage. For water efficiency, a dual flush outlet valve offers the flexibility of half and full flushes, making it a popular choice in modern toilets. With these options, you can find the perfect flush valve to suit your needs and save water.

Different types of toilet flush valves

How to Fix a Faulty Flush Mechanism

1. Remove the cistern lid and inspect the flush mechanism.
2. Check if the flush button is properly connected to the flush valve.
3. Adjust or replace any parts that appear worn or damaged.
4. If you’re not comfortable doing this yourself, it’s best to contact a plumber.

Incorrect Water Level in the Toilet Tank

The water level in your toilet tank plays a crucial role in ensuring a proper flush. If the water level is too low, there may not be enough water to create sufficient flushing power. On the other hand, if the water level is too high, it can cause other issues like a running toilet.

How to Adjust the Water Level in the Toilet Tank

1. Locate the fill valve and the float (usually a ball or cup-shaped device).
2. Adjust the float by bending the arm it’s attached to or turning the adjustment screw.
3. The water level should be about 2.5cm below the top of the overflow tube.
4. Flush the toilet to test if the water level is correct.

Problems with the Fill Valve

The fill valve refills the toilet tank after each flush. If it’s not working correctly, it can affect the water level and, consequently, the toilet’s flushing power.

How to Replace the Fill Valve

  1. Turn off the water supply to the toilet.
  2. Flush the toilet to empty the tank.
  3. Unscrew the fill valve from the bottom of the tank.
  4. Replace it with a new fill valve, following the manufacturer’s instructions.
  5. Turn the water supply back on and check for leaks.

Faulty Flapper

The flapper is a rubber seal that controls the release of water from the tank into the bowl. If it’s damaged or not sealing properly, it can cause weak flushes or continuous running.

How to Fix a Faulty Flapper

1. Turn off the water supply and flush the toilet.
2. Unhook the old flapper from the flush valve.
3. Clean the area around the valve to remove any debris.
4. Install a new flapper, making sure it’s properly seated.
5. Turn the water supply back on and test the flush.

Additional Tips for Maintaining a Working Toilet

To keep your toilet flushing correctly and avoid future plumbing problems, consider these tips:

1. Don’t flush excessive amounts of toilet paper or non-flushable items.
2. Clean your toilet regularly to prevent mineral build-up.
3. Perform periodic checks on the flush mechanism and other components.
4. Address any issues promptly to prevent them from becoming more significant problems.

When to Call a Plumber

While many flushing toilet problems can be resolved with DIY methods, there are times when it’s best to call our Logan Village plumbers:

1. If you’ve tried multiple solutions and your toilet is still not flushing properly.
2. When you suspect a more serious plumbing issue, such as a problem with the main sewer line.
3. If you’re not comfortable performing repairs yourself or lack the necessary tools.
4. When dealing with persistent or recurring flushing problems.

Did You Get Your Toilet to Flush Properly Again?

A toilet that’s not flushing adequately can be a real hassle, but with the right knowledge and tools, you can often fix the problem yourself. By understanding the common reasons behind flushing issues and following the steps outlined in this guide, you’ll be well-equipped to tackle most toilet troubles.

Remember, prevention is always better than cure. Regular hydro jet drain cleaning can keep your pipes flowing smoothly, and checking the toilet cistern every now and again for signs of wear and tear can help spot a maintenance issue before it breaks completely.
