 American Standard Vormax?
Author: george 7941 (Canada)

I got to work on a Vormax for the first time a couple of days ago. What was AS trying to accomplish with the double flappers? Dual Flush? More powerful flow? I also read that water through one flapper cleans the sides while the other flapper feeds the siphon jet, and separating the two functions enables better performance.

Are both flappers supposed to close at the same time or is one supposed to close a bit later?

And what is this with priming the bowl?

How can you prime the bowl any better than ensuring that the water level is as high as it should be by pouring a bit of water into the bowl? What does flushing five times accomplish?
