Thank God nobody was in the kitchen. Yes the upstairs neighbours actually rushed downstairs to check on us. They were panic as well because they didn't expect it to happen. It was not a fire explosion but the pipe plastic gave way causing a sudden burst thereafter the gush out of waterfall of black color debris down on our side.

Neighbours apologized many times and even said will compensate for whatever loss (still pending) as we threw away many things in the kitchen due to acid stain. Meanwhile waiting for a new basin set to come.

Thank you for your concern and hence dropping by here. By the way, over here in Malaysia I yet to hear about neighbours joining together to make the troublemaker move away. I hope there will be no troublemaker that will cause this to happen. Prefer a peaceful neighbourhood. 😉
