Toilet Is Loud When Refilling
Strange toilet sounds can be an indication of an uneven water flow in the supply pipe, which can be solved by adjusting the supply valve located near the tank. According to an article from OnTime59, this can be done by reducing the amount of water that passes through the pipe (2017). This is a common plumbing issue, and its important to address it as soon as its noticed in order to prevent any further damage to the system.

Why is my toilet noisy when flushing?
A noisy toilet when flushing can often be caused by an issue with the refill valve, which can result in the toilet not filling up with enough water. According to Duncan Heating & Air Conditioning (Duncan Htg & AC, 2018), this improper refilling can cause backups in pipes. It is important to ensure your toilet is regularly maintained to prevent such issues.
Noisy toilets are often caused by blocked or loose fill valves, which can be fixed with a few simple steps. According to ToiletHaven's article (2020), the main reason for the noise is a restriction in water flow due to either a blockage or a loose seal. This issue can be solved by replacing the fill valve, cleaning it, or tightening the seal.
Repairing a noisy toilet can be done easily with a quiet fill flush valve. According to wikiHow (2021), there are three main methods to repair a noisy toilet, including installing a quiet fill flush valve, adjusting the float and adjusting the fill level. It is important to remember that in order to repair a noisy toilet, the basic components of the toilet, such as the flapper and fill valve, must be in good working condition.
Troubleshooting noisy toilets can be done easily by inspecting the shut-off valve at the wall and the angle adapter. According to Extreme How To (2020), these two components are typically rigid, plastic pieces connected to the water supply line. With regular maintenance, the noise should be reduced significantly.
Is the noise coming from the toilet?
A high-pitched noise when the toilet fills back up is likely due to either a worn out gasket or a faulty fill valve. According to Home Guides SF Gate, this can be easily fixed by replacing the gasket or the entire valve. It is important to note that if the noise continues, it may be a sign of further plumbing issues with the toilet.
Why is my toilet whining?
A loud whining sound when the toilet tank is filling up can be caused by a worn-out washer on the supply pipe, according to Home Guides SF Gate. Shut off the water, drain the tank and bowl by flushing, sponge up the remaining water, and then loosen both nuts of the supply pipe to replace the washer. Other causes of this sound include a loose fill valve or a worn-out flush valve.
Why is my toilet hissing?
If your toilet is making a hissing noise, it could be due to a faulty inlet valve. According to Bob Vila (2020), this can be fixed with a few simple DIY steps. First, turn off the water supply to the toilet by shutting off the valve.
Next, flush the toilet to drain the tank and locate the inlet valve, which is typically at the bottom of the tank. Replacing the inlet valve should stop the hissing and help maintain a healthy toilet.
Is the toilet leaking?
A loud toilet can often be caused by water leaking from the refill valve or flapper, which can be tracked down and repaired by a plumber. According to Fluidmaster (an international plumbing supply company), it's important to determine the source of the leak to prevent the toilet from making noise. Regular maintenance and checking of these parts can help to reduce potential issues and keep your toilet running smoothly.
Does the toilet fill valve malfunction?
When the toilet fill valve malfunctions, it can cause a high-pitched noise as the water flows through to fill the tank. This is because the fill valve contains a small plastic or nylon piece, shaped like the end of a trumpet, which magnifies the sound of the water. According to eHow (2020), this is a common issue that can be easily fixed with a new fill valve assembly.
How can I fix a toilet water hammer?
Fixing toilet water hammer is possible by first determining the type of toilet, then checking for water leaking into the bowl and resolving any common issues. Fluidmaster provides detailed instructions for cleaning fill valves, adjusting leak sentry valves, and choosing the right flapper for a weak flush. According to Fluidmaster (2020), these steps can help to resolve water hammer noise and pipe knock. Regular maintenance of plumbing fixtures and valves can help to prevent water hammer in the future.
How do I fix a high-pitched whine?
The fix for a high pitched whining sound coming from your toilet when it refills is to turn off the water supply, drain the tank, uncouple the supply line from the bottom of the mechanism, and unscrew the nut that holds the mechanism on (from the outside bottom of the tank). This advice was provided by DIY Stack Exchange in 2020. It is important to insert the new mechanism correctly and attach the supply line securely to ensure it functions properly.
Is the fill valve malfunctioning?
A high-pitched noise coming from your toilet while filling is often caused by a malfunctioning fill valve. According to eHow, this noise continues until the tank is almost completely full and then subsides. This can be a sign of other problems in the plumbing, such as a faulty flapper or worn out gaskets, and should be addressed by a professional plumber.
Can the supply valve be adjusted?
Strange toilet sounds can be an indication of an uneven water flow in the supply pipe, which can be solved by adjusting the supply valve located near the tank. According to an article from OnTime59, this can be done by reducing the amount of water that passes through the pipe (2017). This is a common plumbing issue, and it's important to address it as soon as it's noticed in order to prevent any further damage to the system.
Is there a leak?
To determine the source of a noisy toilet, check for internal water loss or external leakage. According to Fluidmaster (2020), this refill sound usually indicates that the toilet is losing water either internally or externally.
