预防下水道堵塞方法
Prevention of sewer blockage
找一根1米多长的尼龙绳,在绳的前端隔几厘米打一个结,若绳子细,结要打得大一些,有一或几个结即可。将绳末端固定在水管或水龙头上,将打结的前端放人下水管内,然后用大量的水注人水池内,让绳结在水压作用下徐徐进人并超过S型弯道 。
Find a 1 meter long nylon rope, and tie a knot a few centimeters apart at the front of the rope. If the rope is thin, tie it a little larger, just one or more knots. Fix the end of the rope on the water pipe or faucet, put the front end of the knot into the lower water pipe, and then use a large amount of water to inject into the pool, so that the knot can enter slowly under the action of water pressure and exceed the S-shaped curve.
以后如果遇到下水管堵塞,只需往池内注人一定高度的水,然后拉动绳子,此时绳结就会触动堵塞物,并使其在水压作用下被冲走,恢假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温泵复畅通，如果很严重的话，那还是请用专门的下水道疏通机械进行疏通，以免给你带来不方便之处。
In the future, if the water pipe is blocked, just inject water of a certain height into the pool, and then pull the rope, at this time, the knot will touch the blockage, and make it washed away under the action of water pressure, so as to restore smooth flow. If it is serious, please use a special sewer dredger to dredge, so as not to bring inconvenience to you
