I bought a pair of highly-recommended Kohler 1.6 gpf toilets. Both are the first 1.6gpf toilets I've owned.
After a few months of use, I've found that basically, both of them are great unless someone does more than urinate in the toilet. If they do, the toilet requires pretty much two flushes. The problem is that it's usually the next person coming along that finds this out and has to do the flushing.
Obviously we'd like to address that. I opened up both toilets hoping to just extend the left float device to allow more water into the tank but find that both toilets have center assemblies (sorry, I don't know the proper terms here) where the overflow goes that extend right up to the lip of the water. Thus if I raised the float device, the extra water would just flow into the center drain tube forever.
What is everyone doing to deal with this? Is there an extension for the center assembly? Is there a better way?
