Topping up inhibitor?

[ishaqmir]

Hi

7 years ago when the plumber installed brand new combi boiler after power flushing the whole CH system he added a bottle of No Nonsense inhibitor. In the last few years I have taken a radiator off here and there for decoration and then just refilled with water from the boiler. The water in the system is still nice and clear (Magna clean also installed) but I’m sure the inhibitor is too diluted now? Problem is No Nonsense don’t make inhibitor anymore and I’m worried about mixing inhibitors?

Any recommendations? Just one small bottle to add to a radiator I’m about to take off for repair?

Thanks

No problem using another brand

And it’s all ok to just add one bottle without any testing? It’s been 7 years though since any top up

No Nonsense was replaced by Flomasta when Kingfisher consolidated their product brands across their subsidiaries (SF/B&Q/etc). Understanding is it's the same stuff.
