Great valve, bad design.
Bought Glacier Bay N2420 toilet that had this dual flush valve installed and after 6 months, it leaks a refills the toilet every 30-45 minutes throughout the night waking me up!
Found this replacement, sure its cheap, but why keep on buying this every few months?? My 15 year old Glacier Bay basic toilet only had its flapper valve replace twice!
So, this is my fix to this bad design. Make the seal smaller by cutting 1/8" off the outside and pick up a 1/16" rubber gasket sheet from auto parts store and cut out the same seal and put it between the plastic disc and the white seal.
This stopped the leak because the white seal expands over time from use and stops on the water directing channels. Also the white rubber seal develops the seal groove from use and since the arm is at its limit, the seal cant seal and leaks.

It was leaking as soon as I installed it. Not as bad as the one I replaced, but not satisfactory. Will be returning it either for replacement or credit.

Easy solution to seeping seal
My old unit was leaking from the tank into the drainage pipe. The new unit came with a new seal, was easy to install, and solved the problem. Would have been nice, if I could have just gotten a new seal. but could not find one.
