When I had the upstairs bathroom tiled in 1994, that's what I put in to replace a 3.5 Mansfield which served me well. What a MISTAKE that was! That piece of junk is what started a revolving door of toilets which ended in 2005 after I bought my Toto Drake.
That 1994 toilet would gather paper into a ball and plug solid. In order to make it work, you had to flush the paper in small batches.
In the downstairs half bath, the original Crane Galaxy (1986) was replaced with the Universal-Rundle Atlas. Compared to the 1994 Wellworth, it was an improvement, at least it didn't plug as often. That one got replaced too!
The new toilets that are in my home today perform better and more reliably than anything that has been in their place before and have drastically reduced my water bill.
Oh, by the way, I really got even with someone who did me wrong. I gave him my 1994 Wellworth!!!
