【 #Hey hey hey! Check your drains! Know your traps.】
Please bear with Build and Ding’s repeated reminders: traps can only prevent viruses and foul odour from entering your home when they’re regularly filled with water. There are U-shaped, P-shaped, S-shaped and bottle traps, like Tetris! They come in all shapes but serve the same function. Remember to pour around half a litre of water once a week!
