When is it time to change the RO Membrane??

As title says.
Tap 333
After Pre Filters (Changed them today) And RO 51
It's a 5 yr old RO Man system, i would assume it's a HF4 filter?
Is it time to change it?

Yes

We have an RO-man 40-40 running with a 4 year old HF5 - still producing at 006 :o

Crikey, that's really good! I have if i am honest, i have been a little slack changing the pre-filters.
So is it time to change, or is it just a case of whether i want to waste resin?
