hi, I just move in to my new flat which is a resale flat. I am staying at the 2nd storey. The problem is that everyday when i went to the toilet, it always give a bad odour gas. The floor trap is not cover. Both toilet in the kitchen and the master room give a bad smell. Can i ask u all something? Is it bcos the floor trap is not cover or is it i am staying in the lower floor thats why it has bad smell. So what can be done to staop all this???
