The white round piece.... about 1.5 inch diameter.
Apparently ours accidentally got flushed while mom was fixing another seal, and without it that black top pops off every so often.
That low flush volume is required in CA.1.28 GPF you may as well just shit in the yard.
You do not disrespect the mighty Kohler with such tomfoolery.When you call to find out the part #, ask how many Courics each Cimarron model is rated for.
My Kohler in the MBA has that mechanism. It will flush a Buick when called for at 1.3gpf. Respect.You do not disrespect the mighty Kohler with such tomfoolery.
You may however inquire "is that available in Thunder Grey?"
