Ladysmith well water vs a R.O unit question

[DEAD_BY_DAWN]

Hi guys
I was wondering if anyone else on here might be useing a Ro unit in the ladysmith area,i'm going be setting up 240g next month for a freind but the problem is there water has a large amount of sulphur in it,to make this clear when turning on there taps you get a very strong smell of rotten eggs,instead of getting water delivered i was considering a ro unit,but i'm unsure how long it would last under those conditions,any thoughts ?
Thanks john
