So my dad broke the septic clean out cap with the lawn mower. He cannot find a replacement that is lower to the ground so I am printing a new one. Should I use PETG? Or another material. Also I hope this is not violating some form of regulation in the U.S.
ASA is basically inert unless you’re dealing with weird acids or acetone so I don’t worry about the chemistry too much. PETG will generally be a little better chemically but nothing that you’d see in a sewer.
