With the flow rates of the EWP, there is no need for anything larger than 1”, and probably the pressure drop in ¾” would still not be significant unless the runs are long.

Does it matter at all where in the loop the water pump (Davies Craig

EWP)  is located?   Also,  I wanted to run 1.5 hose throughout the

system but it is nearly impossible to build an adaptor block that will

accommodate 1.5 lines. due to space limitations.   More likely the

passages in the block would be less than 1.25 but could be expanded

outside the block to 1.25.   Todd,  how big are the passages through

your  adaptor block?   I am open to suggestions but it looks as if 1.25

i.d. hose is the max if one is using an adaptor block with DC EWP.  

Maziere makes an adaptor block for direct mounting of their pump that

has only .75 passages.  It would be nice to buy their complete system

but Bob's text results seem to favor DC.      Jerry
