danny Posted March 22, 2021 Share Posted March 22, 2021 I have a blocked pipe under the kitchen sink. The procedure I followed to resolve the problem was as follows.1. I inserted the snake into the lower pipe, it is 5 meters in length. I managed to get in 2.60 meters which is the length of the start of the pipe to the wall.2. I then turned the snake with the handle until it passed the wall and I assume descended, I got in total 4.60 meters into the pipe.3. I repeated the same procedure 5 times, each time removing very small amounts of limestone.4. Then I closed off the plug at the start of the pipe and then opened the tap and let water into the system.5. The water overflowed in the washing machine pipe and did the same in the sink drainage pipe, ie it did not drain properly from the sink.6. I again drained all of the water out of the lower pipe and used the snake as indicated above 5 times.7. I then filled the washing machine pipe and the 2 drainer sink pipes with 2.5 liters of hydrochloric acid.8. I left the acid to sit for 3 hours. It is recommended that any blocage should take 20 minutes to work.9. I then ran cold water into both the sink and the washing machine pipes, however, the water did not drain away.10. I then removed the acid from the pipes and inserted the snake again several times.11. I have dis-assembled all of the pipes under the sink and cleaned all of them, however, they showed very little evidence of a blocage.The pipes are still blocked.Can anyone offer advice? I live on the 3rd floor of an apartment building of 12 apartments. The distance from the start of the drainage pipe to the exterior wall of the building is 2.6 meters.
