Low Flow? Flow Meter Not Spinning - D5 Pump in Loop - Page 3

Alright, I can do that. Before I put the flow meter where it is now, I was getting a recurring air bubble there. Any idea why? That's why I put the flow meter there in the first place to monitor the flow...

Try flipping the res over and going pump->cpu->rad->res with the return line going into the bottom of the res.

It is sorta like a second res, but any air in there should get flushed out into the main res,
provided there is a spout going beneath the water surface in the main reservoir which it seems there is.

I just not convinced a flow meter above the reservoir is the cause of his complete lack of flow.
The way I see it, a typical air pocket is kinda like when you have a cup upside down and you push it into water, there's nowhere for the air to go.
Nearly all the air in the flow meter would naturally rise to the top of the loop as water comes in.
A D5 pump could easily blast that air out back into the reservoir.

I have a hunch its cause of the cross flow radiator, that he has an air pocket in there

With a vertical cross flow rad the inlet should be at the bottom, tbat will limit the ammount of air trapped at the top

guys, thanks for all the help. I will try all these suggestions and report back on Thursday. I'm currently on a tight deadline for work.

You appear to have the pump connected by two inlets instead of inlet and outlet. If so of course the pump runs but there will be no flow at all.
A better pic will tell for sure.

Scratch that, I was not familiar with that particular pump top, if its the Darkside model as it looks to be.
On most D5 tops the inlet will be towards the centre of any edge and the outlets will be towards one edge. So it looked as if you were using two centered ports both being inlets.The Darkside is different with both inlet and outlets appearing centred.

You do seem to be using the correct inlet and outlet ports.
