how often should i drain and refil my loop?

I set my loop up in december 13, just wondering how long i should leave it until i drain, flush and refil the loop.

I was thinking of a complete rebuild of the loop and adding a temp sensor+QDC's in August so i was thinking of leaving it until then unless it needs doing every 6 months or something.

I am using mayhems pre-mix i that makes any difference.

I'm tempted to add in another 290, but i don't think i have enough rads to cope with 2 x 290 and CPU.

I keep telling myself i need to drain it at 6 months so i may as well add in a card while i'm doing it lol. I've talked myself out of it though as i don't need anymore GPU grunt for what i use the computer for.
