Generally, inhibitor should be replenished after about three years

Do you really mean replenish (ie drain enough water to insert some more
inhibitor) or flush and refill with fresh inhibitor?

I tend to test once a year and generally find that after three years
the test indicates some loss of efficacy of the inhibitor. At that
point I add more. On the next occasion, I drain, use a flushing
agent and then refill, adding fresh inhibitor.

Ahhhh, that's a point - what do you test with?


Fernox do a kit that you can get at a heating merchant.
