:P yeah i know...

which is why i got the RD-30 instead. :yepp:

I would like to point out that another difference between the two pumps, is that the 3.25 operated 8-13.2vdc and the 3.2 operated 7-12vdc. I'm sure if both pumps were run at their maximum voltages we would see a much larger difference.

Fixed.

I agree this should be tested, but how many people are actually going to run them at higher than 12v on something other than a normal psu?

mcoffey thats a lovely setup

and previously thought dean said 23 dcv.. i assume 13.2 wont do much

mcoffey, would you say the 3.25's are better than the 3.2 pressure wise?

OMG MCOFFY USED A 90 ON THE PUMP INLET!!! STONE HIM!!!

edit: What does XS have against all caps?

When you start up loops with the double pumps like that do you prime the first one with some water and then run the second one or do you just turn them both on straight off the bat??

looks like they would both be primed at the same time. if i were running dual pumps id bleed with just one pump. but ive never tried so :shrug:

When I initially fill my triple-pump loop, I only use the pump attached to the res. Once I get a sufficient amount of fluid in the pump, I run all three since I've found the most airpockets/bubbles form in the pumps that are off (if the system isn't bled fully yet).

i use the wettest pump first...then both of them afterwards

Many thanks guys!

So I'm assuming the current crop of custom pump tops fit? How much nosier is it compared to the "older" gen of pumps?

i really like those new EK v2s...

explain further..i can't seem to understand your suggestion:confused:
