A dripping or stiff tap is often caused by a worn cartridge rather than a faulty tap body. Replacing the cartridge is usually cheaper and quicker than replacing the entire tap.
The challenge is choosing the correct replacement cartridge, as taps use different sizes and types.
This guide explains the best tap cartridge replacement kits, what to look for, and when replacement makes sense.
What a Tap Cartridge Does
The cartridge controls:
- Water flow
- Temperature
- Pressure
Over time, cartridges wear out, causing:
- Drips
- Stiff handles
- Temperature issues

- Must be the correct size
2. Quarter Turn Cartridges
Used in many older taps.
Best for:
- Traditional taps

- Simple design
- Easy to replace
Cons:
- Less forgiving on sizing
3. Universal Replacement Kits

Which Replacement Kit Is Best for Most Homes?
For most DIY repairs, a universal tap cartridge replacement kit is the safest starting point, especially if the tap brand is unknown.
If you know the tap model, a like-for-like ceramic cartridge usually gives the best result.
When to Replace the Whole Tap Instead
Replacing the cartridge may not help if:
- The tap body is damaged
- The threads are worn
- Multiple parts are failing
In those cases, replacing the tap can be more cost-effective.
