A home’s plumbing system plays an integral part in everyday life. However, a whistling toilet during the day or in the middle of the night can disturb your peace, especially if you don’t know where the whistling sound is coming from. These whistles will begin directly when flushing or after flushing and usually persists throughout the entire flushing process.
A whistling toilet could indicate a bigger problem in your home’s plumbing that needs to be fixed. It is also a sign of a problem with your toilet tank fill valve. Keep reading to understand the potential causes of a whistling toilet and what you can do to fix it.
Check the Water Supply Valve
Most of the time, a toilet starts whistling when something restricts the water flow to the toilet. To deal with this, first, check your water supply valve. This valve is located behind the toilet near the wall. And since it’s located close to the ground and easy to turn, it’s easy for children to unknowingly prank their parents by closing the valve.
Turn the valve counterclockwise to ensure it’s completely open. If you still hear a whistling sound, you’ll need to remove the cover to the toilet’s tank and conduct a deeper investigation.
Inspect the Fill Valve
Assuming the water supply valve is open, the next thing to check is the fill valve. The fill valve is a large, plastic piece that’s located inside the tank and controls how much water flows in. If this plastic fill valve isn’t functioning correctly, it can restrict the amount of water flowing into the tank and ultimately cause your toilet to whistle.
This is usually the case for old toilets that operate using a metal ballcock valve. This metal ballcock valve is often located in the rear left corner of the toilet. Try flushing your toilet to see if you can hear where the whistle is coming from.
If the sound is coming from the fill valve, do a visual inspection to see if there is any debris restricting the water flow. This is because, over time, mineral deposits can collect around the fill valve, which can restrict water flow and cause your toilet to whistle. Use a damp rag to wipe any mineral deposits that have collected on the metal ballcock valve.
Worn Out or Damaged Fill Valve
When the toilet fill valve gets old, the pieces and bits holding it together start deteriorating. As a result, your toilet produces a whistling sound after flushing. If you have an old metal ballcock valve toilet, it’s possible to replace the faulty gasket to stop the leaking. If you have a newer ballcock valve, it might be necessary to replace the entire unit, as they are constructed from plastic and are inexpensive.
A plastic fill valve is less likely to create whistling sounds in the future compared to a metal valve. When metal vibrates, it can resonate, creating additional ringing and whistling sounds from the toilet. Newer fill valves are also more efficient than their older counterparts, which allows you to conserve water and save on your water bill.
While it may seem intimidating, replacing a toilet valve is simple and only requires a few tools. Also, make sure you know how to replace the toilet fill valve before attempting this project. Replacing the fill valve is a fairly easy do-it-yourself project that anyone can handle. You will need a few tools, including a wrench, a screwdriver, and pliers.
Here are a few steps for replacing a fill valve once you have the necessary tools:
- Turn off your water supply valve, then flush the toilet.
- Use an old towel or sponge to soak up any remaining water in the tank.
- Use a wrench to disconnect the old supply line from the toilet tank and the fill tube connected to the overflow pipe.
- Next, remove the fill valve by unscrewing the fill valve nut.
- Now, take your new fill valve and insert it into the hole where the old one was.
- Tighten the lock nut in place with the screwdriver.
- Reconnect the water supply line fill tube to the new valve.
- Turn on your water supply valve, then flush the toilet to test it out. If there are no leaks, you’re all done.
If your toilet continues to whistle after replacing the fill valve, there may be a problem with the flapper or flush valve. These parts are located inside the tank and can be replaced following the same steps outlined above. If you feel like your toilet is too old, leading to these problems, don’t hesitate to shop for some best flushing toilets available in the market to avoid future damage.
