Connection of the water pipe will be broken because of water pressure, wearing, tearing, and natural disaster, since the mountain springs has to flow through high mountains to reach its terminal point as families or tea gardens. In order to incessantly offer our citizens the irrigating water, every family has developed a special ability to attach the water pipe, which becomes one of the indispensable life skills for people who live in mountain areas. There must be someone who obtains this kind of ability in our school. Therefore, he can repair the water pipe, when the source of the water is cut off; so far to make the school operate normally and fluently.

        The common material of the water pipe is divided into two categories; one is black rubber pipe and the other is PVC plastics one. The black rubber pipe is more elastic than the PVC one, which can maintain its wonderful state even when the water is frozen. In addition, the black rubber is very convenient to pass through various kinds of topography and forests. Its disadvantages are that it requires high price to purchase, and one should use iron wire to steady and fix it on the wood, which may easily cause the damage of the joint part of the pipeline. On the other hand, advantages of the PVC plastics pipe are that it is cheaper than the black rubber pipe, and it’s easy for workers to construct and build. Moreover, the PVC plastics pipe is much stronger than the black rubber pipe. The shortcoming of it is that it can’t go through all kinds of topography and forests. One should find out an appropriate joint part of the water pipe. The unit of the pipe’s thickness is inch. Different type of water pipe may involve different size of joint part. If the black rubber pipe leaks out water, one should cut the broken region completely, and replace this part with a symmetrical ring. On the other hand, when the plastics tube leaks out water, one should also cut the broken reign wholly, and install the switch to control it. Besides, he should use a large size of circle to connect the joint area of the water pipe. Additionally, in case that the circle will loose, he should also use the viscose to stabilize it.
