where to place csv valve

[psmith32]

Thinking about  my future well layout.
I have high rust content and hard water, therefore, should the csv valve be before the neutralizer tank and rust filter or before?
Possibly place a spin down filter before csv?

Thanks

Use the CSV1A and it can handle the the debris, as you want the CSV before the filters and everything.
