1) When you order this special order item it sets off a chain of events like Willie Wonka in the chocolate factory. Once you turn the valve the chocolate is coming down the pipe. If you then decide you want caramel, the chocolate is still going to come out of the pipe. We can't put the Chocolate back in the pipe, so someone is going to have to eat it, and it's not going to be us! Your order can't be canceled, returned, or magically changed into caramel, so please order carefully the first time!

2) Base is supplied with a closed bottom or with plate across the bottom. Some owners have reported having bases with open bottoms, or the plate cut off. If your existing base does not have a bottom, then you may need to modify this part, cut the bottom off, to match the original configuration.
