How do I know which tap cartridge or thread size fits my tap?

Look for the cartridge diameter or the thread marking on the old part, common sizes on our site are 35mm and 40mm cartridges and thread fittings such as G1/2, G3/8 and G3/4. If you can remove the old cartridge, measure its diameter across the top or take a clear photo; many Architeckt listings are labelled by size or thread (such as the Architeckt 35mm Tap Cartridge or G1/2 Tap Cartridge). If your tap is a branded mixer, matching the manufacturer and model often guarantees a correct fit.

My basin mixer drips, will replacing the cartridge fix it?

In most single lever mixers a worn cartridge is the common cause of dripping, and replacing it is an effective, low‑cost fix. Replacing a 35mm or 40mm cartridge typically restores smooth control and stops leaks, but if the valve body is corroded or the tap is an unusual concealed Hansgrohe wall mixer you may need a specific set such as the hansgrohe Basic Set for concealed wall mounted mixers. Start with the cartridge that matches your tap size; it fixes most dripping and stiffness issues quickly.

Can you refresh the look of your taps by replacing handles or side‑valve fittings?

Yes, you can change handles to alter style without replacing the whole tap, but make sure the new handle matches the valve type and spindle. There are chrome side valve handles in several styles and price points, for example Aquari Prado lever, cylinder or star options and Orchid round or square pairs, plus Architeckt crosshead handles for a more traditional look. Swapping a worn traditional cross for a modern lever can transform the look of your bath while using the existing valve body.

Which spares should you buy if your tap wobbles or you're renewing plumbing connections?

For a loose tap, a tap fixing kit (Architeckt Tap Fixing Kit ranges are available) will secure the mount, and if the flexible supply has perished you’ll want G1/2 flexible tap tails. These small items address common mechanical problems: fixing kits tighten the tap to the basin, and new flexible tails restore reliable water delivery. If you find plastic or corroded parts when you remove the tap, replace both the fixing kit and the tails to avoid repeated work.

How do you choose the right diverter spare for a bath/shower mixer?

Diverters are usually model‑specific, so pick the diverter that matches the mixer shape or model you have, products include diverters for square bathroom taps, round bath shower mixers and for named models such as Malmo, Oxford or Dakota freestanding. A Dakota freestanding bath shower mixer needs the Architeckt Diverter for Dakota, while an Oxford mixer uses the Oxford diverter. Match the diverter style to the mixer to restore correct water routing between bath and shower.
