The problem of toilet water supply and drainage is slow. Solve ahhh

Depending on your situation, it probably feels like the drain is blocked, and if that's not the case downstairs, it's the toilet itself.

There are two possibilities, one is that the S elbow is blocked, and it is very likely that there is no glazed toilet inside, and the flushing is not smooth.

The second is that the sealing ring of the toilet connecting to the sewer is not good, resulting in a bad punch.

The above is the problem of siphon toilets.

In the case of a flush toilet, it is certain that the drain is blocked.

That's a blockage problem, go to a larger supermarket to buy a pipe dredging agent, and use it according to the instructions.

Spoof.

The answers from the buddies upstairs are all good.

Actually, there is another way.

Sprinkle with a spittoon haha.

I think if you're really upset, and you've tried a lot of ways but can't solve it, don't let a toilet installer come and remove the toilet to see what the problem is, it's very simple. It is estimated that it is a toilet problem, and the toilet drain caliber is still very large, and it is generally not blocked.
