I live in a block of flats in China. I had a lot of friends over a couple of days ago and since the toilet, sink and shower are all blocked.
The water on all those items does go down, but really, really slowly. The day after, the water was going down faster, but as of today, it the water is going down slower.
I have just put an auger all the way down the toilet - about 2 meters, but it doesn't seem to have made a difference. I'm going to try putting it down the shower drain as I fear this could be a drain blockage.
When the water from the sink or shower is going down, the toilet water bubbles.
Is this likely to be a drain issue? Is there anything I should keep in mind?
