If you notice that your tap is no longer functioning as it should, it may be time to replace the cartridge. The same applies to shower cartridges, which can also become clogged with mineral deposits.

If the water flow is weak or erratic, that’s a sign that the cartridge might be partially blocked.
Any unusual noises coming from the tap or shower could mean the internal seals are failing and water is letting by.

So if you’re noticing any of these signs, it’s definitely worth considering replacing your tap or shower cartridge.
