How To Fix High-pitched Noise From Shower

It’s not uncommon for showers to make sounds that you haven’t heard before as they age. Whistling and squealing are two of the most common sounds that we hear from showerheads. You may need to consult a plumber in order to diagnose the issue. Sometimes the showerhead needs to be taken apart to determine the cause.

5 Reasons why showers whistle.

Showerheads can make a whistling, squealing or other noises for a variety of reasons.

1. Showerheads need to be retired.

Showerheads are no exception. The inner workings of showerheads can become worn out over time due to use and limescale accumulation. The same showerhead in one area may not last the same amount of time as in another.

2. Your shower head pipe is blocked with limescale.

It’s not just the showerhead that can accumulate limescale but also the pipe leading up to it. The interior of the pipe becomes narrower as more minerals accumulate. This high-speed water flow can produce a high pitch squeal.

Remove your shower head, and clean the pipe using a solution to dissolve the minerals. The metal will not be damaged. White vinegar is usually the answer.

3. The valve that connects to the handles has worn out.

The handle of your shower has a valve. The valve regulates the amount of hot and cold water that is mixed together. This allows you to reach a temperature that is pleasingly warm without being scalding. Over time, this valve may wear out and cause whistling.

4. Replace the diverter valve.

You will find a handle on your shower that allows you to change between the shower head and bathtub faucet. If you hear a squeal while adjusting the handle, this valve is likely to need replacing.

5. The shower cartridge was clogged with debris.

Cartridges are a type of valve found in faucets. They may be inside your shower. Cartridge valves are equipped with holes that allow precise control of water flow and temperature. This is essential for a comfortable and safe shower. Sometimes debris can block the cartridge holes and cause a whistling sound.

It is not always easy to reach the shower valves in order to replace or inspect them. The parts for your shower are hidden behind the wall. Any mistakes can lead to a leak in the floor. You’ll need to hire a plumber for these repairs to avoid further water damage.
