What if the sewer is blocked by sand?

The sewer is blocked by sand. Try to open the inspection port at the bottom of the water storage pipe to discharge the sand. If it doesn't open, flush it out with water. If the sand is mixed with cement or paint, it will be broken. Then find a hose, one end of which is fixed on the faucet, and the other end is wrapped with a towel and stuffed into the sewer entrance. Hold it with your hands and turn on the tap to wash it.

Drainage blockage dredging method:

1, using hydraulic dredging method.

This method is often used in life. Just buy a water pipe, put one end on the faucet and the other end on the blocked place of the pool. At this time, wrap the cloth around the rubber tube, insert it into the drain of the pool, and then turn on the faucet to enlarge the water. Water pressure can usually wash away the blockage.

2. Soda plus vinegar dredging method

This is a very clever chemical dredging method. First pour half a cup of boiled baking soda powder into the pipe, and then add half a cup of vinegar. After the soda reacts with the acid in the vinegar, the sticky things in the pipeline can be removed.

3. Log dredging method

This method is somewhat similar to the first one. Firstly, insert a log stick with a length close to the drain in the pipeline, put a certain amount of water into the pool, and pull the log up and down quickly without interruption. Under the action of suction and pressure, the dirt in the pipeline will be washed away.
