Hi, how did I miss off this key bit of information - yes, 20mm
Cheers, Tom

if that is going to be 700m in one length
you will need good water pressure you get any sort of flow

The pipe's running down a gentle slope - I was worried about too much pressure at the bottom......!

But it's a good point. How do I calculate effects of friction v effects of gravity ?

Id go for 32mm over that length.and make a wheel type thing to put reels of pipe on to unroll it.allway unroll like a toilet roll and never grab an end and walk of.ive seen dozens of people do this over the years.

Ooooh yes @Nick I've seen many pipes kinked in the hands of inexperienced peeps

I allways enjoy seeing them trying to unwind the coil that gets made when an end is pulled.even better if its a 100metre roll
