Toilets are very important elements at home. However, it can’t be helpful when it’s faced with challenges such as whining noise or a whistling sound. It can be frustrating to hear a squealing sound coming from your toilet, especially if you have visitors around or you haven’t dealt with such a problem before.
A squealing sound when your tank is filling may be a result of something simple, like having a partially closed valve or some parts of your ballcock assembly that needs cleaning and replacement. Squealing noise will cause discomfort and increase your water bills if not handled on time.
Here are some of the causes of a squealing sound from your toilet and how you can fix them:
Faulty Fill Valve
The fill valve is responsible for bringing water into the tank. A faulty or old valve can cause a squealing sound on your toilet. Your toilet tank is fitted with a fill valve. The function of the fill valve is to regulate the amount of water that gets into the tank after flushing.
The valve has a float that rises or falls with water inside a toilet tank. The valve opens when the float falls, allowing the water to get into the tank. The valve then closes once the water reaches the preset level, thus preventing more water from getting in.
The internal parts of the fill valve deteriorate with time, leading to a squealing sound in your toilet. A faulty fill valve can also result in the vibration of the entire tank. If you want to confirm that the noise results from a faulty valve, remove the toilet tank lid and slowly lift the float arm. The solution to this is to repair or replace the entire flush valve.
The squealing noise may also occur if the fill valve fails to shut off at the appropriate time. You can solve this by adjusting the float arm to a lesser level inside the toilet tank. There are two different types of floats: a cylinder float and a float ball.
A cylinder float is attached to the body of the fill valve, while a float ball is attached to the rods’end. If you have a cylinder float, squeeze the adjustable clip on the side to lower the float down and ensure the water stops running. Turn the screw in a counterclockwise direction for a float ball until the water ceases running. If you don’t know how to replace your toilet fill valve, then let the professionals tackle it for you.
Calcium Deposits
Other than resulting in toilet flushing so slow, calcium deposits may also make your toilet produce a squealing noise. If you notice a squealing sound when your toilet tank is filling up, there might be a calcium buildup. You’ll experience limescale buildup, especially if you live in areas with hard water.
The buildup prevents the flow of water. If you’re unsure of the calcium buildup, you can check the outer fittings of the toilet. White deposits indicate the presence of calcium. Calcium buildup can clog up the pipes leading to strange sounds. To get rid of this buildup, you can hire professionals to clean your pipes using mineral deposits and calcium.
Water Pressure
If you hear a squealing sound when water is flushing, it could be due to the pressure of the water. It should be noted that toilets use a lot of water, and in areas with high-pressure supply pipes, there is bound to be noise. The sound will vary with the volume of the water.
When water flows rapidly through an obstruction or small openings, it can cause vibrations. The vibration can cause the emission of a squeaking sound if there is a loose area or section. Therefore, if the small pipe passing water to your toilet tank is not large enough to accommodate the water pressure, you’ll hear the squealing sound.
The water pressure at home should range between 40 to 80 PSI. Squealing sounds may develop if the pressure is higher than this. To solve this, regulate the water pressure in your home using a pressure regulator. Also, investing in the best flushing toilets may resolve future water pressure problems with your toilet.
Restricted Water Flow
Another cause of the squealing sound when you flush your toilet is a restricted water flow in the tank. When there’s an obstruction, like a mineral deposit or foreign object, water cannot flow freely in the drain line and will push through with force, causing vibrations.
Your tank may not be receiving enough water if the major shutoff valve attached to the toilet is partially closed. Ensure that the main shutoff valve connected to your toilet is completely open. If your valve is open and there is still water restriction, the chances are that your washers are covered with scale buildup or damaged.
You can solve your water restriction by troubleshooting the ballcock assembly. If your toilet tank suddenly stops flowing or flows slowly when you flush, the filler pipe or the toilet bowl might be clogged. Ensure the float ball is not cracked, or replace it with a new one if it’s cracked.
You should also replace the refill valve if damaged. If the beeping persists, try greasing the fill valve operating surface. You can also disassemble the ballcock assembly, clean each part and then put it back together. If the toilet bowl continues to squeak after all this, your refill valve may be damaged, so replace it.
A Faulty or Worn Out Flapper
Another possible cause of the annoying sound is a faulty or worn-out flapper. A faulty flapper will periodically cause water to leak from the tank to the bowl. This will not only result in noise but will also increase your water bill drastically. To check if this is your problem, remove the flapper and inspect it for wear. If you find that its seat or hinge has been damaged, replace it with a new one.
If there’s no visible damage to the flapper, but it still creaks or squeaks after flushing, you might want to check the chain and spring connecting the flapper with the flush lever. Sometimes they get worn out or damaged, which can cause annoying noises while in use.
FAQs on Why Toilet Squeal After Flushing
Why does my toilet screech after flushing?
It could be because the water level in your tank is too low. When the tank’s water level is below the overflow tube, the drop in pressure can cause a gurgling noise. Another possibility is that your fill valve needs adjusting. If it’s set too low, it can also cause gurgling noises.
Why does my toilet squeal after flushing?
Another common cause of a noisy toilet is that the fill valve seal has become worn or damaged. Over time, the rubber seal can wear down and no longer create a tight enough seal with the flush valve. If this happens, you should replace your fill valve to prevent further noise issues.
Squeaky pipes when flushing toilet. Why?
There are a few reasons why your toilet might make noise after flushing. One of the main causes is that the water level in the tank is too low. Another possible reason is a faulty or old valve that is not sealing properly. Finally, an issue with the water pressure in your home can cause pipes to vibrate and make noise when you flush.
Final Thought on Why Toilet Squeal After Flushing
If you are experiencing a lot of noise from your toilet, it is important to identify the root cause as soon as possible. This will help you prevent further damage and keep your bathroom running smoothly for years to come.
If you are having trouble identifying the source of the noise, it’s better to call in a professional plumber for assistance. They will be able to identify the issue and help you find a solution that works for your home.
