There are a couple of different reasons why your shower may be making a high-pitched squealing or whistling noise. One possible explanation for a shower squealing is that the water pressure is too high. This can cause the pipes to vibrate and make a noise.
Another possible reason is that you have a clogged shower head, and something is blocking the flow of water, such as a build-up of mineral deposits. If you have hard water, this could also be a problem and will call for a water softening system to be put into place.
You can try cleaning the bathroom pipes to see if this solves the shower whistling problem. If not, you may need to call a professional plumber.

Common Showerhead Issues
High water pressure
High water pressure in your home’s plumbing can cause many different problems, including a whistling sound. When water pressure levels are too high, it can cause your pipes to vibrate and knock against each other or your walls. This creates a loud whine or high-pitched squeal.
If you notice your shower making strange noises, it’s essential to have your plumbing and water pressure checked to fix anything acting as a flow restrictor or water pushing a strong force through a narrow passage (1).
Many factors can affect water pressure in your shower, but the most common is the amount of water flowing through your pipes. If you have a high flow rate, you will experience higher water pressure. Conversely, if you have a low flow rate, you will experience lower water pressure. Another factor that can affect water pressure is the height of your water heater.
The higher your water heater is, the more pressure you will experience. Finally, the size of your pipes can also affect water pressure. If you have smaller pipes, you will likely experience lower water pressure than larger pipes.
There are a few ways to adjust the water pressure in your shower. One way is to install a water pressure regulator. This will help regulate water flow into your home and keep the pressure consistent.
Another way to adjust the water pressure in your shower is to change the washer on the showerhead itself. If you have a dishwasher, another option is to use a lower water pressure setting. Finally, if all else fails, you can always call a plumber to come and take a look at your shower.
Mineral deposit build up
Mineral deposits can build up in a shower’s piping over time, causing the water pressure to decrease and eventually leading to clogs. Many factors contribute to the formation of mineral deposits in shower piping.
- One is the type of water you use. Hard water, or water with high mineral content, is more likely to leave behind deposits than soft water.
- Another factor is the temperature of the water. Hotter water speeds up the process of mineral deposit formation.
- Finally, the amount of time water spends sitting in the pipes can also contribute to mineral deposit buildup. If you don’t use your water often, deposits have more time to form.
Mineral deposit, or limescale buildup, can cause a shower to squeal or make noise in a few different ways. Hotels have their own ways of cleaning showers that check for mineral buildup.
First, the deposits can build up on the surface of the shower head, causing it to become clogged and preventing water from flowing through as freely as it should. This can create a high-pitched squealing noise when you turn on the water.
Additionally, the deposits can build up inside the pipes leading to and from the shower head, causing a similar blockage that results in a squealing or noisy sound.
Finally, the deposits can also build up on the shower faucet or tub faucet, preventing it from opening and closing smoothly. This can cause a loud, metallic banging noise when the water is turned on or off.
What is a shower head?
A shower head is a device that attaches to the shower arm and sprays water out of the shower head. Shower heads come in many different designs, but all serve the same purpose: to distribute water over a large area for showers evenly.
Showerheads can be made from various materials, including plastic, metal, or ceramic. They can also be simple in design or have many different features, such as multiple spray settings or massage jets.
A showerhead pipe can cause noise, but it is usually due to a build-up of minerals in the water supply. You can easily fix this by descaling the shower head. Alternatively, you can try adjusting the water pressure to see if that makes a difference. If your shower head is still noisy, it may be time to replace it.
What is a diverter valve?
A diverter valve is a device you can use to control water flow in a plumbing system (1). For example, diverter valves are often used in showers, where they are used to divert water from the shower head to the shower arm.
Diverter valves can be manual or automatic. A lever or knob usually operates manual diverter valves to direct water flow. Automatic diverter valves work through sensors that detect when water is needed in the shower head and divert it accordingly.
Diverter valves can be another culprit of the whistling or squealing in your shower and make noise. The noise is usually caused by a build-up of pressure in the valve, which can cause the valve to vibrate and produce a loud noise.
If you notice that your diverter valve is making noise, it may be due to a faulty diverter valve, and you should contact a plumber to have the valve repaired or replaced.
What is a shower valve?
A shower valve is a device used to control the flow of water in a plumbing system. Shower valves are often used in showers, where they regulate the temperature and flow of water.
Shower valves can be manual or automatic. A lever or knob usually operates manual shower valves to adjust the water flow. Automatic shower valves are operated by sensors that detect when water is needed in the shower head and adjust the flow accordingly.
If your shower valve is making noise, it is likely due to a pressure build-up in the valve. This can cause the valve to vibrate and produce a loud noise. If you notice that your shower valve is making noise, you should contact a plumber to have the valve repaired or replaced.
What is a shower cartridge?
You can use a shower cartridge to control water flow in a plumbing system. Shower cartridges work similarly to the diverter and shower valve. They are often used in showers, where they regulate the temperature and flow of water.
Another culprit of the noise could be a blocked shower cartridge, which often creates a whistling or squealing sound if left alone. You want to get this whistling or squealing sound looked at as soon as possible because further plumbing problems in your water system may worsen over time.
What regulates hot and cold water in my shower?
The water heater in your home regulates the water temperature that flows through your plumbing system. For example, you can set it to a certain temperature, and the shower valve regulates water flow to the shower head.
If you find that your shower’s water isn’t hot, check to see whether your hot water heater needs to be adjusted. If the water in your shower is too hot, you may need to change the amount of water flowing through the shower valve.
