I will be purchasing the pump once I get some more overtime. The pump I will use is a March 809L. I saw a few others that I know would be a lot better, but unfortunately the budget is blowing out as it is, so the $1200 series 335 will have to wait!
I managed to get some brass 1/2" ball valves for the plumbing - eight in total - for about $7.50 each at Reece Plumbing, Wetherill Park. I purchased my copper coil at the same place, also for a bargain, at $121.00 for eighteen metres. This will be used to make 2 x 9 metre counterflow chillers (One of these will go to someone else). I am contemplating the use of that thin black irrigation tubing for the outer shell... but for the sake of a measley $20 difference, I may just use 18mm garden hose instead.
Either way, I am going to have to wait until I have the frame in place before I go ahead with any further plumbing plans. Getting very impatient, though...
Pics coming...
