I’m interested in this from a health standpoint. Does ABS off-gas like PVC? How bad is it? This is for unheated drain pipes only. Does ABS still have BPA?
I once read that ABS used to be very low profit margin compared to PVC so they started cutting it with fillers. I’ve have a few bad experiences with consumer goods made out of ABS that smell like mold and are extremely difficult to clean. Could this have anything to do with it?
I would consider other materials if they were anywhere close in price and easy to work with.
