Quick radiator flushing question

[4737Joker]

Just about to rinse out my new rads, going to use boiled water from the kettle a few times until clear, then as I don't have any deionised or distilled water I was wondering If I could just use a bit of my mayhems pre mix to swill them out?

yes you can, however using pre mix to rinse out a rad is a bit of a waste, you can get DI water from most supermarkets or Halfords if you have one near

to be honest, as long as you tip your rads till every drop of tap water that you can possibly get out is out then just filling your loop with the premix will be fine

Thanks, just getting going now, I'll just tip it all out and let them air while I pre assemble everything else, then just fill it and see how it goes.

Thanks for the reply.
