1, if the cement stone fell into the sewer time is relatively short, this situation can find a stick, poke while using a bucket of water, and then wash down until the cement stone washed down.
2, if the cement stone fell for a long time, has been solidified, this situation needs to contact professional dredging personnel with tools to deal with, first with the pipe dredging machine a little bit of cement broken, and then water to wash it away.
3, slight cement block blockage, you can first pour boiling water into the sewer, then pour cold water, repeated several times. At this time, the water pipe is in a state of thermal expansion and cold contraction, and the cement block can be separated from the pipe.
1. Prepare long pole, pull hook, grab hedge and other tools, tie the pull hook to one end of the long pole, and fix it.

2. Extend the hook part into the area blocked by sand and gravel in the water pipeline, shake the rod, hook out the blockage such as sand and leaves, and then remove it with the hedge rake.

3, after the sand and stone are dredged clean, the water pipe entrance is covered with a fine wire mesh, which can effectively filter out the relatively large sand and stone, leaves, etc., to prevent the blockage problem again.
If the distance is not too far, you can consider using a stick to try and see if you can disrupt the stone, and then wash it off with a lot of water. If not, then you can impact the stone with a professional electric pipe drain to ensure that the stone can be disrupted. You need to be careful not to destroy the pipeline, and then flush it with a lot of water
