Quote:Sorry if I wasn't clear on my post but I know how to solder. My concern was on the flux eating away at the pipework. Would flushing the system via a mains pressure suffice? Obviously I won't be able to add any flushing chemicals.
Thanks again

I don't think anyone suggested you didn't, but if you know how to solder, you will apply flux to the pipe only, and as a result very little flux will get in the pipe.
When you have completed the pipework you should water pressure test it, after which you can drain down and flush with mains water, drain down and cap any open ends.
