hi, first.. woohoo another NZ'er
i was just wondering where you got your copper from and how much it was ?
also, for a pump, i dunno if there still is but there was someone on trademe.co.nz who sold pumps, theyre ahh Resun brand

but i got one, it was $65NZD and i havent had any problems with it.. well actually i have, i broke the impeller thing off it but that was my fault (its not good to drop your pump

) its ahh 1000LPH and got a 2m head. but since you got one it dosnt really matter now.
