Why does my shower sound like a motor?

There are many reasons why your shower may be making sounds like a motor. Check out some of the causes below;

What does it mean when your shower makes high-pitched noise?

The high-pitched sound you hear when you use your shower may mean the washers inside the water valve are worn out.

It can also be caused by a loosened cartridge or unsecured pipes.
