I was offered and certainly took advantage of a generous offer for a replacement.
Changes in design of tank connections require replacement of perfectly functioning faucet.
There is no longer a drain outlet at bottom of tank formerly used to remove sediment. Instructions now say to remove tank and drain by inverting tank. IE no way to flush tank.
This is tantamount to a reinstallation, not for the faint of heart as garbage disposal in some instances will also have to be removed.
What was a 15 min cleaning is now, by my plumbers estimate, over $100.
Might as well wait until it fails again and then replace. "New and Improved?"
