Review on Fluidmaster 400ARHRKP10 PerforMAX Universal Performance by William Sanchez

So after removing the tank from my bowl, I found that the bowl gasket that came in the kit doesn't remotely resemble the old one I just removed. The old one was a triangular gasket that was placed on top of the flush valve and inserted through the holes in the tank. (As you insert the bolts the gasket will mushroom and form a gasket.) At this point I decided to break out of the enclosed instructions and the gasket section says this is not for Kohler 2pc. toilets! Bow! So I had to order it for another $12 or so. Fast forward, got the right gasket, everything installed, no leaks. So I flushed the new arm and it is not set to page flush. The instructions say you can bend to your specifications as long as you bend it in the designated area. I did, and it broke where indicated. Glad you kept the old lever. So everything went back. This experience was very disappointing and upsetting. My fault for not checking it out first and luckily we have two bathrooms. But the description should draw your attention to the seal. The lever was cheap plastic.
