Both my washing machine and kitchen sink drain to this main drainage pipe on the kitchen floor.... recently when both are drain at the same time, the water was being force out due to slow drainage to the common pipe - sign of choking. This morning, without even using the washing machine, just washing at the sink, the water runs out....but still drained very slowly..... then I use the aluminium broom handle and shove it down the pipe, pieces of white solid block float up and I removes it..... now it seems like TOTAL CHOKE
When I look above the ceiling, checking how my above neighbor's drainage pipe looks like, a normal U shape, but funny I can't feel any opening all around at the bottom of the pipe with the aluminium handle.... so I wonder if I get those "snake flimsy metal rod" , I wonder can it penetrate and clear those solidified waste since those wire are so flimsy....
any advice?
