Your business is done and you have now pulled the handle of your toilet. There is a familiar sound of water swirling, but nothing else happens. What’s the deal? Continue reading to find out what causes toilet swirls that won’t flush

It is possible that your toilet isn’t getting enough water to the bowl fast enough to flush. You can increase the water level by increasing the float at your fill valve.

You can then pour muriatic acid into your overflow valve, and wait for half an hour before flushing. Use eye protection, gloves, an apron, as well as adequate ventilation.

How Does The Toilet Flush Work?

The inlet valves on your toilet bowl release water from the tank through the holes at the lip. This happens each time you pull on the flush lever.

This causes the water level to rise suddenly, allowing it to reach the P-trap. This is the pipe that curves upwards at the back of the toilet. This is what also holds the water in the toilet bowl’s bottom in place.

The sewer drain seals against the air below when the water starts to flow down. This creates suction, drawing water back. This process continues until there’s no more water in the bowl.

Possible causes of toilet swirls during flushing

If your toilet can’t get enough water quickly enough to make significant suction, it won’t be able to produce enough momentum. Alternately, the water may not be able to exit the drainpipe fast enough to cause the same effect.

When the toilet swirls, it indicates that water is entering. If the water level doesn’t rise, it could be that the problem isn’t getting enough water.

This will cause water to flow over the pipe’s crest. While you may be able to remove some of the waste, it might not create enough suction for all the waste in your tank.

The problem lies in the drainpipe. If the water level rises or drains slowly, it could be a sign that the drainpipe is clogged. You will need to clear the drainpipe from any clogs.

There is not enough water in the tank

There could be many reasons why the tank isn’t full. Below are the most common issues and fixes.

Adjust the Float Ball

You will have less water in your toilet tank if the float ball is too low. This could lead to the toilet not flushing properly. This can be fixed by adjusting the float ball.

How to adjust a toilet float ball
  • Take off the lid from the toilet tank. It should be left aside
  • The tank’s water level should be checked. If the tank has no line, the water level should be approximately one inch below the overflow tube.
  • You must empty the toilet tank. Turn off the water shutoff valve. This valve is located behind your toilet. Next, flush the toilet. If necessary, repeat this process.
  • Take a look at the float ball. Check to see if it has water. If it has water in it, it should be replaced.
  • Inspect the float ball. Check if the float ball is too high or low.
  • Adjust the float ball. Use a screwdriver to adjust the height. To increase the water level, turn the screw at the fill valve clockwise.
  • To check the level of the water is correct, turn on the water again and flush the toilet.

Clogged Inlet Valves

The inlet valves may become blocked, which could slow down the flow of water into the bowl. This could be due to gradual mineral buildup. The first and most straightforward solution is to safely pour muriatic Acid into an overflow tube. Wait for half an hour.

If you don’t want or need to use harsh acids, there is an alternative.

Method To Unclog Inlet Valve

  • In the overflow tube, pour hot vinegar. Heat several cups of vinegar until it reaches at least 120°F. Do not flush.
  • Clear blockages from the inlets with a stiff wire. Start at the bowl’s rim and work your way down. This job is best done with a wire coat hanger, but depending on how close the clog to the bowl’s rim is, a paperclip may work as well.
  • A water softener can prevent the problem from returning. They can prevent hard water buildup and reduce the mineral content.

Drain Pipe Clogs

There are many solutions to a blocked drainpipe. We will, however, address the problem in the most comprehensive way.

How to Unclog Your Drain Pipes

  • Fill a bucket full of water. You should have enough water to fill your toilet bowl. If you can, aim for five gallons.
  • Place it in the toilet bowl. It is important to make sure that the water does not spill onto the floor.
  • To flush the toilet. You can also use a plunger to attempt to remove the clog if the water doesn’t break it apart on its own.
  • Use an auger. If none of these options work, you can use an auger. Place it in the drainpipe. Rotate clockwise, while turning counterclockwise.

Frequently Asked Questions

Unless I hold the handle down, why my toilet won’t flush properly?

The chain that lifts up the flapper to flush the toilet is too long. This causes the flapper to lift up as you press the lever. The chain is too long, so the flapper does not close fast enough.

The chain that attaches to the flapper must be slightly shorter to fix this problem. These steps will help you adjust the chain.

  • Take off the lid.
  • Turn the clockwise direction to turn off the water supply. Flush the toilet.
  • Unhook the chain. It is likely that there is a hook connecting it to the flush handle.
  • Make the chain slightly shorter by hooking it back to the flush handle.
  • Verify that the toilet flushes correctly.
  • If it is not, adjust the chain.

Why won’t my toilets flush, it only swirls?

Your main sewer line could be blocked if your toilets don’t flush. You will likely find several blocked drains in your house if this happens.

The drains will likely gurgle. You may also notice water coming up from one drain if you use another drain. If this happens, there are some things you can do. You should still call a plumber to avoid causing damage to your pipes.

  • Do not let the pressure build-up: Locate your drain cleaner. It is usually a capped pipe that will be located in your backyard or front yard. However, it may be on your roof.
  • To clear obstructions in your sewer line, you can rent a sewer snake or a sewer jetter.
  • If tree roots are the problem, you might try chemicals. Although you could flush an herbicide-based root-killing foam down your toilet, it may take a while to clear the clog.

You may need to call a plumber if you have a complicated problem.

What is causing my toilet swirls?

Because the normal flow of toilet water is blocked, the water in the toilet swirls. There are many causes for toilet water to stop flowing, including low-flow flush systems and clogged inlet holes.

Before you attempt to fix your toilet, it is important to identify the root cause.

Wrapping Up

You can fix toilet swirls that won’t flush in just a few minutes. You can fix the problem by replacing the flapper or the flush handle chain. However, the tank water level and clogs could also be the culprit.
