A shower cartridge is one of the latest technologies to give you a better showering experience. It’s a part of some of the modern shower valves.
Shower cartridges can last for a long time, given that it was installed and used appropriately.
Some signs that your shower cartridge is either partially damaged or entirely broken are dripping, irregular temperature, rigid controls, etc.
What Does a Shower Cartridge Do?
A shower cartridge sits inside the valve behind your faucet. The cartridge decides the flow and temperature of the water.
Inside the cartridge, hot and cold water is mixed, and when you pull the handle, it allows the water to flow by sliding and opening built-in holes.
Depending on your preference, the cartridge then diverts the water to the shower head or faucet.

How Does a Shower Cartridge Fail?
The balance between hot and cold water is essential to ensure the longevity of the cartridge. If the water in your home is too cold and the boiler produces water which is the opposite, it can damage your valve in the long run.
You can minimize the damage by slowly turning your faucet every time you mix the hot and cold water.
Hard water will lessen the lifespan of your cartridge as well. However, you can install a water softener in your bathroom if you have a hard water supply in your area.
If you don’t turn off the water supply entirely after using the shower, eventually, because of the drip, the cartridge will start to accumulate minerals. It might prevent the cartridge from blocking the water supply entirely if it happens for an extended period.
