Great question — answering as the UphillTech team:
I'm unfamiliar with solvent connected waste pipes, but in general any solvent weld is usable after just a few minutes. It's a very quick process. The silicone caulk used at the base should be left alone for 12 to 24 hours. If you press on it with a blunt pointed object it should feel firm.
