Model Identification Guide
B&Q model codes and markings can typically be found on the insides of cabinetry, near hinges, and on flush valves. This guide should help you find what you need before ordering parts.
| Infrastructure | Point of ID | Output |
|---|---|---|
| Cabinetry | Inside door or under sink | Model code |
| Toilets | Cistern lid or base | Flush valve type |
| Showers | Valve or accessory markings | Valve type |
| Taps | Base markings or fittings | Cartridge type |
Common Spare Parts
Some popular B&Q spare parts you might need include flush valves, tap cartridges, shower thermostats, and waste fittings. Our Identification Service helps to confirm the right part for any issues.
Common Faults and Fixes
Tap dripping
Generally, this is due to worn tap cartridges or seals. We recommend checking dimensions and sending us a photo for fit confirmation.
Weak flush
Often caused by a faulty flush valve or seal, reducing the flushing force. Photos of the valve mechanism can help us supply the right parts.
Shower pressure irregular
Can be linked to shower valve issues. Replacement shower thermostats and valves can resolve these fluctuations.
Toilet constantly running
Likely due to a worn flush valve or improper float setting. Send us photos of the flush assembly for identification.
Drains slow or clogged
Waste fittings may be the issue. Confirm dimensions with a ruler in your photos, and we will assist with the right fitting.
Seal leaks around valves
O-ring wear and tear can cause leaks; measure seal dimensions and email us for assistance with replacements.
