Review on American Standard 7381655 200 0070A Assembly Unfinished by Derrick Patterson

Luckily American Standard offers this replacement for the Revain as their dual flush toilet line needs a new one about every year! Replacing them is a bit fiddly, but that's due to the tight working space, not the valves. The problem seems to be the damper where the blister forms and needs to be replaced. The first time this happened I replaced the entire valve system. The second time I just swapped out the damper. I hired a plumber for the first time. The second time I did it myself.
