Storm water pipes were installed before guttering etc. Location of the downpipe didnt line up so they came back to "fix" it. This doesnt look right to me but i don't know if its not to code. In SA. These are on the boundary of the garage and the pipe runs underneath the slab. I would assume you want as few bends as possible as otherwise you can get back pressure in a heavy downpour. Any help please. Want to fix before paths and driveway get concreted over
Pipe goes through the slab to the left of this photo and the right comes towards the bottom to pick up drains
Reverse angle where the pipe going under the slab goes to the right
Front of the garage. Bottom is capped, pipe to right goes across to pick up other downpipe on other side of garage then out to street. Pipe goes under garage is the bottom one

The pipes look like they will meet the mandatory minimal surface coverage once you landscape. The plumbing is legal.
I would assume you want as few bends as possible as otherwise you can get back pressure in a heavy downpour.
Downpipes never hold less than 3/4 of their volume as air unless they have a physical or hydraulic restriction. The water flowing down the downpipe will have no additional flow restriction within the downpipe..
