I have a blocked drain below the waste stack. I have lifted the manhole access cover further down the line but as there are three covers, each with 4 differnet pipes, I am unsure of which one is the pipe for my blocked waste. When fitted the stack was fitted to an existing stack (the house is 110 years old) and once started to be used soon became blocked. How can I find out in which direction this pipe travel? I have a concern that the pipe, due to its age may have collapsed and therefore is not blocked by the normal waste but by a collapsed pipe, any tips are more than welcome before I start on this job tomorrow!
