Step 3: Dismantling pipes and sink
Before releasing the pipe place a bucket under the pipes for draining left over water in pipes. Next open the hot and cold water pipe connections. Every tap and plumbing system is a bit different in my case I had to disconnect the pipes from both sides in order to be able to lift the sink and tap out.
If your sink has connectors under it release them with a screw gun.
Push connectors back and lift sink out. Release old tap with a spanner.
