I read about that from some sites, forgotten where but I have it cut and pasted into my preparation notes.
I'm not really sure about this though
Here's the original version :
"I have yet heard is to sleeve the 10mm barb fittings (or use a reducer) and connect a balance pipe (by means of T-pieces or Y-connectors) to counteract any flow restriction induced by this"
Maybe I should do it like this,
pump outlet-->largest possible tube--->reducer--->10mm tube--->res.--->10mm tube--->rad--->10mm tube--->reducer--->1/2"ID--->pelt block--->1/2" ID--->pelt block 2--->largest possible tube--->pump inlet.
hows this sound?
Thanks a lot!!
