I’m having issues with our soil pipe that runs over our garage. Last year we had a toilet blockage and when we had folk out to clear it they ended up dislodging a pipe with the snake and flooded the garage via the ceiling and fuse box. All the sewage sodden ceiling was taken down and replaced. It’s now happened again. We have a blockage that’s leaking through the garage in the same two places (fortunately just beside the fuse box this time, rather than through it, as the volume of water is less than last time). The folk that repaired it last time are saying that there is an issue with the way our builder installed the pipe work. I don’t know if this is the case and that the pipework is faulty and should have been clipped or if it’s ok as is and the repair was botched last year. Can anyone check the photos I took last year while the pipes were exposed and see if they can see any possible issues there might be and anything we might need to do to get the pipework up to standard to avoid this happening again. Any advice is gratefully received!
Should this soil pipe be clipped?

What’s the fall on the pipe ? Should be between 1 in 40 to1in110 for horizontal run.

They’re not the best photos. Hard to tell, it looks like it’s resting on some battens.
As mentioned above, the pipe looks to be unclipped and flat with no falls.
Possibly, the flatness means that heavy sludge can separate from the liquid and gradually build up to a blockage.
When attempts to clear the blockage are made the heavy blockage could be pushed into the fitting (s) and unsettle or disconnect it if its a push fit fitting.
It will keep happening so you must expose the whole run of 110mm soil pipe and fittings from start to finish and do it properly with clip, falls, solvent cement and access points for cleaning.
Alternatively, you can find a new way to re-route the soil pipe?

Possibly not the best of installations, but still shouldn't come apart under normal circumstances, but difficult to say exactly without being on site to look.. I'd get a second opinion, if the Folks who came last time said it wasn't right, did they offer any solutions to putting it right?
Soil pipe ideally needs to be on a 1:40 fall (Gradient), although as little as 1:100 can be got away with in some situations. If it's blocking, it does beg the question, Is there any fall or even a backfall on the pipe? Again, would need to be checked by someone who knows what they're looking for. I'd also say all waste pipe connections need to be done with Solvent Welded joints, to eliminate the possibility of those coming apart and/or leaking.
Also have to ask, do you use wipes, even the 'flushable' type?
