Yes, but the pipes in the old community are in disrepair for a long time and are relatively thin, which may block the sewers. But as long as you don't throw those non-food wastes that can't be ground in and use them reasonably according to the principles of the instructions, you won't. I live in an old neighborhood myself, and I have been using Okde's kitchen waste disposer with my neighbors for a long time, and there has been no problem.
