The Toto toilet is one of the most popular toilets on the market today. This doesn’t come as a surprise seeing as the model has earned a reputation for being both reliable and durable. However, that does not mean that it is immune to problems.
One of the main problems with it has to do with flushing. Are you one of the people asking why is my Toto toilet making noise after flushing? If so, then we have outlined a few reasons why that may be happening and what you can do to fix it.
A Bad Flapper Valve
A bad flapper valve can cause your toilet to make a loud noise when you flush it. The flapper is a rubber gasket that seals the bottom of the toilet tank, allowing water to fill the tank and then flush down the toilet. It closes when there’s enough water in the tank.
If it doesn’t close properly, it will make a loud noise when you flush your toilet.
This usually happens when water leaks into or around the flapper valve. This can happen if you have a cracked or damaged flapper valve or if there’s an air bubble trapped between the lid and frame of your toilet. Water entering around the flapper may also occur if something gets caught in between it and its seal on top of your toilet bowl.
An Overflowing Tank
The second reason why your toilet may make noise after flushing is that there’s too much water in the tank when you flush.
When this happens, air bubbles are trapped inside your toilet, and this causes it to make a noise when it flushes or even fills up completely with water. This type of noise may also occur when you flush after using a bidet that has been left running. This is particularly true if yours has a nozzle.
Accumulated Calcium in the Pipes
Another common reason why your Toto toilet is making noise after flushing is calcium buildup in the pipes. This can be caused by hard water, which has more calcium than soft water.
If you only have access to hard water, it’s best to invest in a filter for your faucet and showerhead to prevent this issue from happening in the future. You can also consider adding vinegar to your toilet bowl every few months to help clean it out and prevent calcium buildup as well.
Worn Out/Malfunctioning Flapper
If there’s a clunking noise when you flush the toilet or the water doesn’t seem to be draining properly, it could be caused by a worn-out flapper. The flapper is a rubber gasket that seals off the inside of your toilet tank from water.
It is typically made from soft rubber and can become brittle over time. If it has deteriorated enough, it will not seal properly, which can cause water to leak into your toilet bowl and make a noise as it does so. For this reason, it’s important to replace your flapper if it’s worn out or damaged in any way.
Broken Suction Valve
Another common reason for a noisy toilet is a broken suction valve, which regulates how much water goes into the bowl and how much comes out during flushing. These are usually easy to fix with parts that you can easily access at your local hardware store, but if you’re not comfortable doing so yourself, you can always enlist the services of a professional plumber.
Malfunctioning Toilet Handle
Toilet handles get a lot of wear and tear over time, and they can sometimes malfunction. If you hear a noise from your toilet after flushing, it’s possible that the handle has become worn or broken, which will cause it to stick all the way down when you try to flush.
The handle can also become stuck because of a buildup of dirt or debris around it or even if you’ve accidentally put something in there. If this is the case, take off the handle by using pliers or a wrench, then clean out whatever is causing the problem.
Damaged Drain Pipe
Your toilet may be making noise because there is something wrong with its drain pipe. If you’ve ever had a problem with clogged plumbing, you know how frustrating it can be to clean it up. The same thing can happen to your toilet if there is something stuck in the drain pipe.
You might have a small plastic or metal object that’s been washed down the drain and into your toilet bowl. Or maybe there’s an obstruction in the pipe itself or some other problem causing water to back up into your toilet.
To fix this problem, you’ll need to remove any blockage from your drain pipe using a plunger or putty knife. Once it’s removed, clean out as much debris as possible from inside your toilet and fill it with water again so that any remaining blockage can be flushed away.
How to Check for Issues that Could Be Causing the Noise After Flushing
- The first thing to check is if there is any debris or other foreign objects in your toilet tank. There may be a small piece of hair, food, or even a small piece of paper that could be causing the noise.
- If you find something that looks like it might be causing the problem, remove it and try flushing the toilet again. If this doesn’t fix it, it may be time to check your entire plumbing system.
- To check if there is an issue with your plumbing, turn on the water to your house and run a hose into the drain pipe where your toilet sits (it should be connected to another pipe coming out of your house). If water starts flowing out of this pipe, then you can be sure that there is something wrong with it, and it will need further repair work done by a licensed plumber.
- Another thing to check is if there are any leaks around your toilet tank or anywhere else in its vicinity. If you find any leaks at all, then take note of where they are located so that you can have them fixed before anything else happens to them.
- Finally, make sure that nothing is blocking up any part of the plumbing system near where your toilet sits
