Like many here, I recently broke a hydrometer. Luckily I didn't need it right away, as I broke it while cleaning it after brewing. Got me thinking about the need for redundancy with my equipment. Specifically, my hydrometer, glass thermometer and bottle capper. I was thinking that if I broke my red plastic capper half way through bottling a batch I might be screwed. Anyone else have redundancy in this or any other equipment? Do cappers break?
