The Singapore under sink plumbing set up is different than what I’ve seen in the states for the most part. This set up is pretty nice in many ways but also seems to clog up more frequently than most of the standard US p-traps I’m used to dealing with. This is really nice in the sense that when it does clog up you just put your water catch basin under the sink and unscrew the receptacle, dump it out, and screw it back on. Really a great set up if you ask me. The problem I saw was that it leaked no matter how tight I tightened it by hand once it was full of food waste debris.
Here’s some good plumbing/unclogging tools to have:
