I have a soil pipe that runs from the back of the house to the front and out to a manhole cover in front of the house. It runs slow and blocks about twice a year. The pipe has sunk about 100mm about 2m into the living room at the front of the house, so that one section is partly full of water. I know this because a drain specialist ran a camera down it.
I can live with it but having spent the last hour up to my elbow in poo it would nice to fix it for good.
Is there anyway to fix this without having to dig up the living room floor?
I'm not sure there is... I'm assuming you are quite carefull about not flushing big wads of toilet paper etc. down it? It might not be the poo that's the problem if its accompanied by sanitary pads, wet wipes etc...?
I’ve had a cracked drain between the stink pipe and the manhole lined with a fancy expanding and setting flexible liner, all done without digging along the run, but that wouldn’t solve the pooling and slow flow if the fall angles are messed up. New spade for Christmas?
We had an inspection after the neighbour was having issues. Turned out we had a collapsed section. It was in the shared bit so the water company's problem. The chap who did the inspection said it could be fixed with a sleeve. When the guys came to fix it they dug it up and put new pipe in. Didn't take long but it was under the patio not the house
I'm pretty certain it's dishwasher detergent that blocks it. No signs of paper or pads. It always gets clogged with a dryish block of white powdery stuff. It doesn't feel greasy like fat.

Ahh, that's a starting point then...I don't have a dishwasher so I don't know, but I'd start by looking at alternative dishwasher detergents that's less claggy etc. I mean If it's contributing to blocking your drain, it won't be doing the dishwasher much good either?
Is there any option to 'rebore' the route of the pipe and put a new pipe in ? With the borer starting outside the house?
(Smaller pipe issue but the gas pipe to next door runs through our garden and on the cusp of the porch. It collapsed a few years back, and the gas board installed a new one by boring a new hole from a hole they dug in the road. They had to dig a small hole in my garden where the pipe Tee'd off to my meter, but avoided having to did a big 20 yard long trench across the garden / front of the house.
If a pipe has sunk 100mm then it's a major fault, can't think why it would fail , is it clay plastic ? It would come out the sockets and never work , don't know how you can tell 100mm without it all exposed
If possible re route it around your building but if you don't know what you're doing best get someone in. If it's a concrete floor I'd expect major cracks and if a suspended timber floor a health concern and a constant manky smell
If the pipe is full of water and dry either side then that's going to a minimum of a 100mm drop in the sunken section.
