Rated 4 out of 5 by from Seems to work Used it after pipework & radiator alteration works. Connected up to filling look & seemed to work but can never be sure.

Rated 1 out of 5 by from Applicator broken This review is based on the applicator only. Mine was broken when delivered. It appears to have some sort of trigger attachment that misleads you into thinking that the trigger will dispense the liquid. It will not. If you screw the applicator into the can before screwing the other end into your radiator it will dispense the liquid all over the place (as obviously experienced by a previous reviewer). The trigger is entirely redundant and misleading.

Rated 5 out of 5 by from Does what it says on the tin. Good easy to use product, heard good thing about the Fernox range, time will tell if it has done its job. I applied to an empty system and the can emptied very quickly around 1 second, i wasn't sure it had gone in but it did can was now empty and cold.

Hello, I have standard copper radiator pipes mixed with plastic pipes. Can this product be used with plastic heating pipes?

Can this be used in conjunction with the leak sealer!?

Asked by: Westy88
Hello Westy88. All the F Range chemicals are designed to be used in conjunction with each other, so you can use F1 Protector with F4 Leak Sealer. Hope this helps.

Can this be mixed with other brands of inhibitor?

Asked by: Micky5
Hello Micky5. Unfortunately we don't advise that you mix F1 with any other inhibitor. The F1 Express can be mixed with any other chemicals in the F range, however we cannot guarantee that the F1 would work in conjunction with other inhibitors.

radiators already treated with Fernox is it ok to just add to top up protection

Asked by: HoSh
Hello Hosh. You can't overdose a system with the F1 Protector, so adding any extra to top up the system will have no adverse effects.

Bought this by mistake. Is it OK to add it straight into the header tank instead of into the rad.

Asked by: SteveBDIY
Hello Steve, this will be fine to add via the header tank.
