Weak jet: screen and aerator
Undo, wash, measure the thread. Scale ≠ cartridge. No DIY in-wall tap.
A crooked or pin-jet is often a lime-blocked aerator screen, not a tap to replace. First move: shut the water if needed, undo the nozzle, rinse the mesh. Many basins have a concealed aerator and need the kit key.
M22, M24 and M28 are not a guess. Measure the thread before you buy. A ten-piece pack is a category example, not an order.
If the male thread drips on refitting, two or three turns of PTFE with the thread. If the spout drips, PTFE is the wrong tool: washer or cartridge. Stripped thread or a leak from the wall: a plumber.
What to do now (€ 0)
- Undo the nozzle (concealed key or by hand on the thread).
- Rinse the screen.
- Scale: vinegar in a bag 20–40 min, if the material allows it.
Minimal DIY
Household moves, not a building site. A stick and a deodoriser do not fill a dry trap and do not repair the sewer.
