Jul 16, 2023 | 0 comments

A toilet that doesn’t flush properly can be a significant source of inconvenience. It can lead to water wastage, unsanitary conditions, and unexpected repair costs. If your toilet isn’t flushing as it should, don’t worry – there are numerous ways to improve its performance. In this comprehensive guide, we’ll explore the different techniques on how to make your toilet flush better.

1. Adjust the Water Level in the Tank

A low water level in the tank can lead to a weak flush. The water level in your toilet tank should be about half an inch below the overflow tube. To adjust the water level:

Adjust the Water Level in the Tank
  • Locate the fill valve in your toilet tank. It’s typically on the left side.
  • Adjust the float that controls the fill valve. Depending on your toilet model, you may need to turn a screw or slide a clip along a rod.
  • Flush your toilet to test the new water level. Adjust again if necessary.

2. Clean the Rim Jets

The rim jets, located under the rim of the toilet bowl, release water into the bowl during a flush. Over time, they can become clogged with mineral deposits, reducing their effectiveness. To clean the rim jets:

Clean the Rim Jets
  • Use a mirror to locate the jets under the rim of your toilet bowl.
  • Use a toilet cleaning solution and a thin wire to dislodge any blockages.
  • Flush the toilet to rinse away the debris.

3. Replace the Flapper

If your toilet isn’t holding water as it should, it might have a faulty flapper. To replace the flapper:

Replace the Flapper
  • Turn off the water supply to your toilet and flush to empty the tank.
  • Remove the old flapper.
  • Purchase a new flapper of the same type and install it.
  • Turn the water supply back on and let the tank fill. Test the flush.

4. Fix the Clogs

If your toilet is not flushing well and takes a long time to empty and fill up again, it might be because something is blocking the pipes. You can check if this is the case by pouring a lot of hot water into the toilet bowl. If the water doesn’t go down, it means there is a blockage. o fix a clogged toilet, you can try the following steps:

Fix the Clogs
  • Turn off the water supply to the toilet by closing the valve behind the toilet.
  • Use a plunger to try and dislodge the blockage. Make sure there is enough water in the bowl to cover the rubber part of the plunger. Place the plunger over the drain hole and push down and up rapidly several times.
  • If the plunger doesn’t work, try using a plumbing snake or auger. Insert it into the drain hole and turn the handle clockwise until you feel resistance. This means you have reached the clog. Push and pull the snake until the blockage is dislodged.
  • If none of these methods work, you may need to call a plumber to fix the problem.

Once the blockage is cleared, turn the water supply back on and flush the toilet to ensure that it is working properly.

5. Clean the Flush Holes

To make your toilet flush better, it’s important to clean the flush holes and siphon jets in your toilet bowl, which are located under the rim and help flush water and waste. Mineral deposits can clog these holes and affect the toilet’s performance. Here are some easy steps to clean them:

Clean the Flush Holes
  • Turn off the water supply and flush the toilet to empty the tank.
  • Cover the flush holes with waterproof duct tape.
  • Pour white vinegar into the tank.
  • Leave the vinegar to soak for at least 30 minutes.
  • Remove the tape and turn the water supply back on after soaking.
  • Flush the toilet a few times to clear out the vinegar.

Common Toilet Issues and Their Solutions

There are many issues with toilets that require professional assistance, but not all problems necessitate a plumber. Some contemporary toilet models include user manuals that homeowners can consult when facing an issue. Here are some of the most common issues: 

Slow Filling Toilet: If your toilet is slow to fill, it might be due to a problem with the fill valve or water supply line. Check if the valve is fully open. If it is, but the toilet is still slow to fill, consider replacing the fill valve.

Partial Flush: A partial flush often indicates a problem with the flapper. If it closes too soon, not enough water is released into the bowl. Adjust the chain length connecting the flapper to the flush lever for better results.

Phantom Flush: A phantom flush or a toilet that starts refilling on its own indicates a slow leak from the tank into the bowl. This is commonly due to a worn-out flapper or a fill valve issue. Replace the flapper or the fill valve to resolve this.

Clogged Toilet: A clogged toilet results in a weak flush. Use a plunger to dislodge the clog. If that fails, a plumber’s snake or auger can help. Also, there are various types of clog removers you can use.

When to Call a Plumber

While many toilet flush problems can be fixed with DIY solutions, some issues require professional help. If you’ve tried the above solutions and your toilet still doesn’t flush properly, or if you notice leaks around your toilet, it’s time to call a plumber.
