No 5: When was it last used? This morning 6: How long has it been sitting? Since I took over, it's only missed a day. Before that I think it was used pretty regularly. 7: How does it smell and from whom did you get it? Smells like coffee, no bad smell, just used/stale/old coffee and I got it off my brother-in-law for $100. FYI, needed a coffee this morning so i put it back together and the new seal stopped the leak.
