Sulphuric acid can damage some plastics but mainly the bendy accordion style or metal pipes.
If it is used in drain cleaners some additives must be used to slow it’s reactivity. Lye, or NaOH, has one disadvantage - it makes scares and then you feel burning. H2SO4 burns and then makes scares.

That’s worrying just because I have a suspicion that there are accordion pipes. So I just did a test. Plugged the drain & filled the sink to the top with water. Pulled the plug and ran to the basement. There is a strong gushing from the main pipe. So I’d say at least most of the water is going to the right place. So certainly it’s not a case where the sewage found a complete alternate path. The clog is in fact gone. Though there’s always a chance of leaks, which in this case would be into or below a concrete slab.

Do you know concentration of the acid? I think it is only case in higher concentrations like 80% or above.

Maybe if I track down the MSDS it might say, but I can say for sure that this is labelled as a pro drain cleaner for that purpose. So it’s not likely laboratory or military grade or anything intense.

Ok seems like 90% or above with these additives it should be fine.
