I think I have a leak in the pipes coming from the reseviour that holds the coolant and anti freeze - I want to use Radwelds coolant leek and have been told because of the age of the car i will need to use a speed flush first - its asking to drain the radiator first how do i do this?

Cheaper, quicker and better all round to replace the hose.

Allways a bad idea to use things like rad weld.

Stops the leak, initially, so you use it again. same.
What happens, over a period of time, it builds up.
Terrible to get rid of.
I do car air con, same thing, use one of the seal and fill jobs. Yes it solves the imediate problem. BUT over time no good, I have to use special filters, incase some one has used an aditive. Cost me more, SO costs you more.
Get the leak fixed.
