    Adding Fernox Protector F1 mixing up

    Hello Gents, I need to add some inhibitor to the boiler so I have got some Fernox F1 My question is can this be added to a system with other additives already in the system? The additive already in the system is Sentinel Leak Sealer will this be OK to do? thanks

    Adding Fernox DS40 to system via magnetic filter chamber

    I'm planing to use Fernox DS40 to clear out a microbore blockage. I can't use the one of those funnel things for radiators as the radiators are quite narrow and do not have the type of bleed valve where you can screw in the funnel. The heating system is closed, but it does have a MagnaClean...
