Hi everyone. I am trying to fathom the sewer drainage system in my house. I lifted the sewage manhole cover outside my house (one is for outside guttering, the other internal), and see stagnant water which smells and is slow to drain
The main pipe exits here into two pipes, one big one above a smaller one. The smaller one was full of small black silt deposits, from where I do not know. I tried to remove them by hand, but could only reach so far. I do not know whether this small one is blocked off by design or whether its been blocked by some obstruction
The upper pipe is flowing freely, but because its elevated, sewage only flows into it once it rises few cm above the lower smaller one.
I just wanted some advice whether this was normal at all or what I can do?
Here's the visible upper pipe, smaller pipe beneath it is submerged
Manhole cover outside garage
Some kind of black rock like deposits?
