Hey Rich,
You need to upgrade that toilet.
Sounds like you need to get a Thunderflush 5000.
Their all aluminum watercooled, with all stainless hardware, and a pressure rated neoprene sealing ring. I think they have an optional polymer bowl liner, and superwide carbon fiber seats also.
They come standard with steel-flex, but may wear prematurely depending on severity of service.
I heard they will clear an Orlando phonebook on 1.5 gallons per flush, while swirling at 300 rpm's!
I think the high end models are guaranteed to reliably flush 5 acres of rain Forest, or your money back.
