    We are looking at a 1985 Mansfield toilet I believe. Maybe installed in 1988 or sooner.
    It is being replaced due to poor performance. I never did like the 3.5's and anywhere I have lived I tend to remove and toss them, replacing them with newer high performance toilets.


    Mansfield 3.5 GPF toilet.


    This fill valve lasted a long time.



    Concealed trapway on the old bowls.


    Replaced with one of my favorites, the TOTO Drake CST744S elongated.
    This one has the Bemis wood painted seat.

    In my experience, those 80s Mansfields have been pretty decent, but that new Drake is a far better replacement.
