Replaced the lock valves on radiators and drained complete system, so on filling up, added this to give it a go. Boiler is slightly quieter now after month of adding it, but I could be getting deafer. Reliability one star as does the product have that?

I normally buy the named brands but my local store did not have any so thought i try this.
Considering the boiler sounded like it was possessed it worked as good as the Â£20 treatments.
I will be using this in the future :)
