The blue toilet cleaner in the toilet tank is poured into the water pipe, and the blue liquid comes

This is terrifying, unless the water and sewer lines are connected, and there have been such rare cases reported, it is recommended to investigate in time.

Has there been any water in the house? If so, it's the water in the tank, because someone turned on the faucet when the kitchen was out of water, causing negative pressure and causing the water to flow backwards. If it's caused by your upstairs neighbor's use of toilet cleaner, you can suggest that he install a check valve so that the water in his toilet won't flow back up when the water stops again.

After each water stop, pay attention to the water stored in the pipe for a while, and wait for the water to be clear before using it.

There is an inlet pipe in the toilet tank, just insert the inlet pipe into a vertical cylindrical cylinder.

There's no good way around this.

Every time I encounter a water stop, I always put a large amount of water away first, and then use it after the water has no peculiar smell, no color, and no impurities; Or hold back for a period of time and then use it after releasing the water (that is, let others put it first).

Hello, it is normal for this problem to be possible.

Because the water outlet pipe in your kitchen belongs to the water pipe, and the toilet belongs to the sewer pipe, not a system pipe, how can blue liquid appear.

And if it's the wrong connection, it's not just a blue liquid, you know.

Is the water pipe connected wrong, shouldn't be?

What else can I do Change the water pipe, that thing is poisonous.
