I have seen several posts indicating this shouldn't be left in longer than 3 hours with an aluminium HE, and others saying it is ok. The bottle says it is ok for aluminium so am I right in thinking I am safe to chuck a bottle in tomorrow evening and run it overnight before flushing through the day after?
Sentinel X800 overnight?

- Start date
I think the formulation of X800 was changed fairly recently as Sentinel say that it is suitable for all metals including aluminium.
It's a copper HE on the Standard efficiency. It's just coated. Why do you think it's needs doing?

I dont know the history of the system as I only moved in a year ago, but I do know we have one very rusty radiator in need of replacing and another that has a blocked feed pipe. I want to make sure the system is in a reasonable condition, replace that rusty rad and then add inhibitor to protect the internals.
ok, I wondered about replacing the rad first in case any treatment put the final nail in the coffin! It is rusty in several places on the outside, the most worrying bit is the plug at the top is very corroded and doing a slow drip.
