What Can You Do?

Pliers and pipe cleaners are the simplest solution.

First, turn off the water from the main line. This is not as essential as you may think, but you can prevent slipping and water damage to the bathroom. To turn off the water, locate the water valve and set it to its “OFF” mode.

Adjusting the water pressure can be done by anybody, as it is easy to do. You only need a wrench and a screwdriver.

Once done, tighten back the nuts and turn on the water.

Go back to the bathroom and test the shower. Run it for 5 minutes. If there is no evidence of rattling or humming sounds, then you have solved the issue. Otherwise, do it again and consider that noisy sounds are caused by other things.
