I'm thinking about making a small sink for my DIY lab. Since there is no running water or drain, I was thinking about something similar to a camping sink like this one.
I'd make some modifications (e.g. using a ceramic basin rather than a plastic one, since it will be fixed).
Now, for the water reservoir any container is fine, but I have doubts about the material of the drain plumbing and container. I'd usually use it to wash the hands (so only water + soap), but I'd also occasionally use it to wash tools and items, which can include also chemicals (e.g. ferric chloride to etch PCBs).
What material is usually used in these cases, and what are its limitations? (e.g. this plastic is ok for acids but when used with gasoline breaks).
For instance I found containers and pipes in PE or PVC or PP; is any of these materials suitable?
