After chipping the edge of the bathroom basin of the apartment I'm renting, I've attempted to install a replacement in order to save costs. This is my first plumbing project!
I speculate that the plumbing here is quite old - the piping is metal and there is a separate cold and hot tap as opposed to a mixer. The apartment complex also appears to be built in the 1970s.
I've managed to turn off the water at the apartment's main, disconnect the supply lines, disconnect the drainage pipe, and pull the basin off. Luckily, the new basin fits in the wall brackets of the original basin!
The new basin sits approximately ~5cm (~2 inches) above the drainage pipe.
What is the most practical solution for me to bridge this gap? Is it better for me to replace the entire drain pipe & sink trap, or is it possible for me to source a pvc adapter that fits perfectly into this gap?
Additionally, the drain pipe looks pretty gangster - there is some string which I assume was acting as a substitute for irregular threading, or to prevent leaking?
