This is the original OEM factory 2 1/2 quart water pan for the E2 Type 12 (Black, Silver, e2 Gold Series), and E-2 (e SERIES™) Rainbow vacuum cleaning system. We do not sell aftermarket water pans as reviews and experience have shown them to be inferior in quality and more likely to break. We also offer a larger 4 quart water pan that is nice when picking up a lot of dirt as it gives more water for the dirt to filter through. It also allows for more water pickup when you have a spill or are shampooing. Original item number R7876 was a 2 quart design before it was replaced with this larger standard 2 1/2 quart version. The early version also had a silver warning label with item number R6853 in the lower corner.
