6 Possible Reasons Behind The Bathtub Faucet Making Loud Noise

Bathtub faucets making loud noises can put you in distress. You must fix this right away. And to do so, you need to identify the reasons behind the faucet making the noise first. 

Don’t worry, we’ve mentioned 6 common causes as to why bathtub faucets make loud noises. Check it out and figure out your reason.

Reason 1: Mineral Deposits

Over time, mineral deposits such as magnesium, calcium, and potassium can form inside the faucets. These minerals have the potential to clog pipes and impede water flow. You may have observed similar deposits on your showerheads as well. And these clogs have friction with water, making the noise.


Resolving this issue is not that complex, but make sure you don’t waste any time. Because mineral deposits in water for too long can lead to long-term problems.

To begin, disassemble and check your system’s valves. Then remove the mineral deposits, temperature pressure valves, showerheads, and control valves.

Then use vinegar or another hard water cleanser to clean it. If necessary, you can also replace the valve.

Reason 2: Excessive Water Pressure

An abrupt change in water pressure can occasionally cause a phenomenon known as water hammering. When water travels quickly through a pipe, loud noises are heard. But it faces resistance as a result of an elbow or a partially closed valve.


Now before you start, make sure the water valve is completely open. If the noise persists, you might have to lower the water pressure. Then lower the water pressure at the house main. 

You may also consider adding pressure control shut-off valves with the right size to them.

Reason 3: Loose Parts Of The Bathtub Faucet

Another common reason for squeaking bathtub faucets is loose pieces in the faucet itself. It could be a faulty screw or valve. 

The vibrations are caused due to water running against the loose object. And it’s most likely what’s causing the annoying noise.

The water flow could be suddenly restricted as a result of this disturbance. To put it another way, it goes from having a lot of space to being crammed into a little space.

Not only that but loose parts of the faucets could gradually cause additional problems as well. Like the faucets can eventually get off and sprinkle water. But if you have peerless or delta faucets, you may interchange them


Remove the plate covering the screw that holds the lever in place first. You can remove this little plate from most single lever faucets with a thin-bladed knife. 

Then tighten the screws that keep the loose portions of the lever in place. Wrap the valve stem in plumber’s tape after that.

If you might find all these difficult, then don’t go any further. Because you might cause disruption in the internal parts if you do something with any confusion. In that case, you can always take help from professionals.

Reason 4: Faulty Mixing Valve Cartridge

This issue could be due to a malfunctioning mixing valve cartridge. This is what regulates the hot and cold water flow. 

But it’s not always the case. You may notice that the noise only occurs when you turn on the shower diverter. In such a scenario, this is unlikely to be the source of your problem. 

A noisy bathtub faucet is frequently caused by a malfunctioning mixing valve cartridge. This can also result in a malfunctioning showerhead. Another spot where the flow of water changes abruptly is here.


To fix this issue, we would recommend you to take help from professionals. You might think it’s simple but it’s better if you avoid this operation yourself.

Reason 5: Clogged Pipes Of The Showerheads

The water is discharged from the tank through a pipe that runs through your wall. The water then travels to the showerhead, where it must pass through a small hole. 

Occasionally, any little particles from the tank or elsewhere clog the pipe. As a result, when the water tries to squeeze through, it generates a whistling noise.


Remove the showerhead and clean the showerhead pipe to resolve the problem. Replacing an old showerhead is sometimes the simplest answer. Minerals in the water might accumulate over time and block the little nozzles. 

Not sure what showerhead to use? Worry not, we’ve got you a couple of suggestions below-

It’s simple to replace your showerhead with a new one. And check whether it resolves the whistling issue. This is similar to unclogging the toilet. But if it still has this issue then get help from a professional to resolve the issue.

Reason 6: Binding Or Worn Threads

A high-pitched, screeching whistle may be heard when you turn the faucet handle. The metal threads of the faucet assembly could be the root of the problem. 

The threads of the stem rub against the threads of your faucet, causing this noise.


A simple remedy is to use petroleum jelly to lather both threads. This provides just enough lubrication to keep the surfaces from sticking together. But to get the most out of your repair, double-check the thread quality.

If the threads appear to be worn, the parts may need to be replaced. If this is not done, lubrication will not be sufficient to fix the problem.

These are the major causes behind the bathtub faucet making loud noises. Make sure to resolve the issue without any delay.


Question: How to fix the shower noises?

Answer: For one hour, soak the showerhead distilled vinegar in a bowl. It would be able to loosen mineral deposits as a result of this. Wipe the mineral deposits off the outside of the showerhead with a toothbrush or scrub brush. Then, on the shower arm, change the showerhead. Finally, turn on the water and listen for any sounds.

Question: What to do about the noisy water pipes?

Answer: Turn off your main water supply first. Then turn on the taps on your home’s upper story. Now turn on the taps on your home’s lower level. Allow your system to drain completely. Turn the water supply back on once there is no more water pouring out of your taps.

Question: Why do the pipes make noise after flushing the toilet?

Answer: When you flush the toilet, a lot of water goes through those pipes. As the toilet fills up, it abruptly closes a valve. It also causes water to slam on it. This causes noise and vibration, and the pipe may occasionally crash against the wall. But if you hear noises with extremely high pitch, then seek assistance from the experts. They can fix the issue.
