I think post 139 above should have the answer, as I believe that Globe Union makes the Water Ridge toilets for Costco:
"My Costco single piece dual flush tank is slowly leaking and I hear it refill occasionally, and one of the flush buttons wasn't fully popping back up into place (although enough to fully clear the flush mechanism, so that the water refilled and stopped).
I called Globe Union 866-789-2273 and went through the call-tree to selecting Consumer and then Parts. They asked about the color of the flush mechanism and determined it was an older design (yellow track down the side). They are sending an updated flush mechanism (blue on side), the plungers that go into the tank cover, and a new seat; all under warranty at no charge.
They sent a confirmation email with installation instructions. It looks like a 20 minute task, requiring only a philips screwdriver."
