and watch the video but my Internet wouldn't down load the video. I read the manual and promo sheet but didn't see any comparison numbers. I believe we use less then two qts. to flush on a regular basis but with the other flush options maybe it will average out. I seem to remember that you suggested not to purchase the raw water flush option. Is that a hard and fast suggestion or are you just leaning that way for cost control? The wiring diagram looks pretty straight forward and so does the plumbing. All the hoses would come up from under the bowl in approximately the same place as with my Junior so installation wouldn't be very hard.
