BF,
Just finished plumbing mine and Ive used a minimum of 5 (inc boiler) ball valves. Could possibly use another 3, but I reckon thats bordering on overkill...
I'll try and get some pics later..
Thanks Linz I'm not sure of where to place those darn taps. I have an idea but I would like to see someone who has got a system working....
:super:
