I replaced our garbage disposal which was on its last legs this past weekend. Everyone I talk too seems to be amazed that I didn’t just wait for it to break. I think it’s better to replace it now when it’s clean and empty rather than do it after it’s broken and it was full of wet, disgusting goo. It wasn’t going to last much longer anyway. Plus the removal and replacement wasn’t nearly as gross of a task as it might have been.
