Setting up two d5's in serial question/s

[TumbleButt]

1.) When I'm filling the loop, do I run the first pump first and run it through the other pump and run both of them once its "full enough"?
2a.) Will there be any downsides with flow rate in that scenario?

2b.) Will the downsides be negligible?

A question for you:
Why would you even want two D5s for your loop?

Redundancy (the peace of mind that if one pump does go down, atleast the other will still run)

imo not worth the price / bother / noise / power / space.

 

If redunancy it such a problem I would just have a backup motor at the ready ( I even think that you can swap motor's without completly draining )

If your asking about wether you should run one while filling the loop, then your right. Just run one D5, the one connected to the res and it will force the liquid through the other one, no damage done.

One, I don't want to debate whether its worth the price or not.

And no, I want a rig that runs while cooled. I don't want a pump to suddenly fail because reasons while I'm in the middle of work or gaming and I suddenly get BSOD because my PC is tapping out due to heat or my rig gets demolished or get a lower lifespan due to the heat it tanked.

Thank you very much for your reply

Another question, though. When do I start running the second pump? When the entire loop is filled? Or just enough when the water has passed through?

For safety I would say when the whole loop is filled up, but you should be able to run it when there is enough water to pass through. The only thing you shouldn't do is let it run dry.

Okay, thank you very much
