What’s Inside a Shower Mixer?
A shower mixer is a valve that regulates water flow and temperature. The cartridge inside it is the key player, managing how much hot and cold water mix together. Over time, wear and tear can cause the cartridge to fail, resulting in leaks from the showerhead or mixer body. Fixing it promptly can save you from bigger plumbing headaches.
How a Broken Cartridge Causes Leaks
The cartridge has moving parts and seals that degrade with use. When it breaks, you might notice:
Leaking water from the showerhead or mixer, even when turned off.
Temperature issues, making it hard to get the right mix of hot and cold.
Strange noises, like whistling or gurgling, from the mixer.
Low water pressure, indicating a blockage or failure inside.
A broken cartridge disrupts the mixer’s ability to seal properly, letting water escape where it shouldn’t.
Different Sizes of Shower Mixer Cartridges
Cartridges aren’t one-size-fits-all. They come in various sizes, typically:
35mm
40mm
45mm
