A garbage disposal is incompatible with a standard corrugated drain hose. Back home — in London, Chicago, Sydney — it worked fine because the plumbing was designed around it from the start. Here, installers connect it to whatever's already there: a flexible accordion drain, a bottle trap, push-fit nuts with no real locking mechanism. A few weeks later, you notice dampness under the sink. Then a smell. Then a puddle. This isn't a manufacturing fault — it's a specific mechanical incompatibility, and it can be fixed in a single visit. Any competent handyman can redo the drain in an hour to an hour and a half, provided they know exactly what needs to change.
