There are three methods for detecting the slope of the bathroom floor, which one do you agree with?

Today, let’s talk about three methods for detecting the slope of the bathroom floor. If you search these three methods on the Internet, there will be a lot of videos.

The first method is to do a slope test with water, put the water pipe at the door of the bathroom, put water in it, put a little ink in the water, and the ink will flow away from the floor drain along the water.

This test is relatively successful, because the pressure of the tap water is relatively large, and the flow direction of the water is the direction of the floor drain.

In the state of water flow, the ink flows in the direction of the floor drain, which is only the first part of the test. The second part should be to turn off the tap water, and immediately sprinkle a little more ink on the ground to see if the water flows in the direction of the floor drain at this time.

The second method is to use a table tennis ball to detect the slope. If you want to use this method, the table tennis ball should be thrown near the floor drain. If you put the table tennis ball from the bathroom door, there is a high chance that the table tennis ball will not roll to the position of the floor drain. .

This is not because the slope is not well done, but because the ping pong ball is too light, and now there are gaps between the floor tiles. The ping pong ball rolls very slowly.

I used ping pong balls for the test a few days ago, and it was only successful once I did it more than 10 times. I don’t think it makes much sense to use this method for slope detection.

The third is to use glass balls or steel balls. Put the glass balls or steel balls at the beginning of the slope and see if they can roll naturally to the floor drain.

Think about it, everyone, are you seeing these three detection methods?

Of these three inspection methods, I agree with the last one, using glass beads or steel balls, without wetting the original ground, and can really simulate the actual situation.

The purpose of the experiment is to prove the result. If you discard the result and show it off, you will lose the meaning of the experiment.
