Few days ago we noticed that our kitchen sink is leaking. After investigation it was water line which needs replacing.
On Saturday I disassembled whole kitchen sink and checked which else parts would be nice to replace (washers, pipes etc). Wife decided that we will also change tap (kitchen retractable spout mixer type). Visit in local store gave me needed components and then fight started.
Took me 3 hours to finally mount everything in place without any leaks (but I had to disassemble it few times to fix mounts) but final result is nice — no water under sink and new shinny tap.
