A few years ago, a couple of Flapper valve flushing toilets were installed
at my parents place. These only ever last about a year before the rubber
disc starts leaking into the pan, and is found to be covered in hard
water scale. Do these things really only last about a year before needing
maintenance, or are these two particularly bad for some reason?

I think that they are simply the wrong type of flush for use in a hard
water area.
Our water is as hard a snails and traditional syphons run for years. In
34 years here I've replaced one syphon lift diaphragm/plastic sheet and
that split due to old age rather than any scale problems.
Our taps have to be stripped and descaled every 5 years or so but no
scale problems in the cisterns.

Got two here - about ten years or so old. No problem with them at all
except having to clean and then spray the button mechanism with, I
think, silicone.

The chrome on one of the push buttons looks decidedly tatty now compared
with new. Not dreadful but might fit a new one.

Have flapper in a house abroad at least 14 years old and still going
strong. Hard water area. I have only once had a small leak and it was
cured by cleaning the seal around the flapper area.
