Coffee Grounds Down The Drain: Are They OK?

Can Coffee Grounds Go Down the Sink?

You may be thinking, “But I pour them down the sink drain every day and I’ve never had a clogged drain!” You see, coffee grounds come from coffee beans, which are virtually rock hard by the time they’re ground and brewed. You certainly wouldn’t want to grind up the pit from a peach, apricot, or nectarine that is about just as hard because they wouldn’t break down like other foods, and it’s the same with coffee beans!

If you usually grind coffee beans in the garbage disposal because it seems the cleanest and convenient, we don’t fault you for that. And anyone who has ever had to clean up the trash with spilled coffee grounds after a dog got into it would understand the rationale. Unfortunately, coffee grounds do not break down in water, so instead of grinding up and washing away as normal foods do in a garbage disposal, they clump together and as time goes by, the grounds can form a clump and pack the drain until it develops a clog.
