A waste that drains slowly
The same sink logic: mechanical before chemical.
If it is one appliance, treat the trap, not the block. A plunger, a strip-down, a short snake if hair is past the waste.
A 10 m cable or a drill is not minimal DIY. If it returns in an hour, or other wastes fill, stop.
What to do now (€ 0)
- Plunger on the sink (not the WC cup, or wash it).
- Bucket + undo the trap + pull the hair. No caustic soda as a first move.
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.
