The parts within the valves have a lifespan of 15 to 20 years. Over time, wear and tear, plus the accumulation of limescale, from precipitation of hard water minerals in the water, cause parts to fail or leak. For continued safe and enjoyable use of your shower system, the cartridge and other parts of the valve should be replaced every 15 years.

Indicators That You Should Replace the Pressure Balance Shower Cartridge

  • Inconsistent Water Temperature: If you notice frequent fluctuations in water temperature that the cartridge fails to correct, it may be a sign that the cartridge is worn out or malfunctioning.
  • Reduced Water Pressure: A significant drop in water pressure, even after cleaning the cartridge, can indicate that it is no longer functioning properly.
  • Leaks and Drips: Persistent leaking or dripping from the showerhead or valve area suggests that the cartridge seals are failing and need replacement.
  • Strange Noises: Unusual noises such as banging, whistling, or groaning sounds during water flow can be a symptom of a failing cartridge.
  • Limescale Buildup: If upon inspection, the cartridge shows buildup of hard water limescale, it should be cleaned or replaced.
  • Physical Damage: Visible signs of damage, such as cracks or severe corrosion, are clear indicators that the cartridge should be replaced.

Fixing Water Leak

If water leaks from the center of the valve cover:

  • Replace the White Washer.
  • Replace the Medium Rubber O-Ring. Apply silicone-based plumber's grease to the O-Ring before installing it.

You should also replace the Pressure Balance Cartridge and Valve Filters, if you have not already done so.
