The answer to 'what causes shower' is that there are several common causes for shower issues, including clogged drains, leaks, low water pressure, and problems with the shower head or faucet. Clogged drains are one of the most frequent causes, where hair, soap scum, and other debris build up and restrict water flow. Leaks can occur around the shower door, faucet, or even in the pipes behind the walls, leading to water damage. Low water pressure is often caused by mineral buildup in the pipes or issues with the home's water heater or main water supply. Problems with the shower head or faucet, such as worn washers or broken parts, can also lead to poor water flow or leaks.
In many cases, these issues can be resolved with some basic DIY troubleshooting and repairs. However, for more complex problems or if you're not comfortable doing the work yourself, it's best to call in a professional plumber to diagnose and fix the issue.
