First picker row selection changes second picker row - objective-c

Question

Ive picked up some code form another developer which im trying to put right. One of the problems is:
I have 2 pickers that fill a text box with selected row from a picker.
If picker 1 (named: Type) is selected, the row selected ..say row 3, defaults to that row on my next picker (named: FlueType) when the picker is presented.
How can I get the second picker not be affected by the first pickers row selection?
Ive looked at [picker reloadComponent:0]; I've looked on stack and google and cant seem to find anything that fits this problem.
Ive also tried [picker selectRow:0 inComponent:0 animated:NO] in the ViewDidLoad method hoping that it would set all my pickers to the first row value which is all im trying to do.
Apologies for the mountain of code, I've tried to separate it out into context
