Loop finished, only one leak so far, no disaster...

I'm back...

So I filled the pump up with water, and ran a hose from the inlet into a bowl of water out the kitchen. I left a hose connnected the outlet in the air but naturally, facing towards the bowl.

I jump started the pump, and it made a very loud whirring sound, and the water just pulsated about 4 inches up and down the outlet pipe. It sounded like a moped that would revving low
 
Well..-

Use pliers or pay 4x more for the same thing from bits power...my fittings cost under £30 to get the same from bits power would have been £100+...

Yea OK :rolleyes:

My fittings look better.

U jelly?

edit: oic now I know which post this is, it's regarding rotaries where pliers don't apply.

My D5 whined like crazy (to the point I thought it was faulty) when I first started running fluid through it. It quietened down after 5-10 mins though. I put it down to the pump being dry.

So have you managed constant flow with the pump or is it just pulsing?

To be clear, do you have a bowl of water acting as a res with both inlet and outlet of the pump hooked into the bowl of water?
 
it was just pulsing.

I ran a pipe from the bowl into the inlet, but left the outlet pipe out of the water, and it pulsed up and down the outlet pipe.

I had already filled the res up with tap water first of course.
 
Try connect the outlet to the res and see if you can maintain a constant flow, if its pulsing it sounds like the pump isn't working as it should.
 
It sounds very likely to me you haven't primed the pump properly. Before you swicth the pump one there should be no air whatsover eith in the pump or in the inlet tube all the way to the res, or in this case, bowl. If there is then the pump will just try to suck air up the inlet, then burn out.
 
^^^ Possibly, but going on all previous info about the system overheating, it does kind of point to the pump.
 
Where does the D5 feed from? I thought as long as the reservoir was full and you kept it full, it doesnt matter. I've never run the pump with the reservoir empty. Always kept it full. Always started it up with coolant in it. The only thing I've done is disconnect the inlet a few times because of having to change the configuration of my sli bridge. Should I of disconnected the outlet when I did it?
 
Yes. The one in the v12 kit. Black res with xspc in silver on the front and a d5 screwed on the back. What initially made me suspect something was up, was turning the red screw on the back made no difference to pump noise.
 
Speaking as a cylinder res user, I have about 2" of tubing between my res and my pump, upon filling as soon as I hit the power the pump near instantly makes the fluid in the res vanish.

Is it possible for you to upload a short video? Just showing some tubing linking the in and out of the res/pump combo with the power on.

Pulsing it shouldn't do, to me it sounds like the red dial is fudged and its stopped the pump for putting any real power behind it.

If this pump is faulty its almost certainly the cause of your erratic temps.
 
So when you tested it just now, the res was full and the pipes were connected and put into the bowl? If so, then i stand by what i say that the pump is faulty.

That pump should be able put water out the end of the tube like a tap running.

Completely agree.
 
Sound, no rush buddy, I'll be about until the wee hours of the morning anyway as the new ace combat game has nearly finished downloading :D

@*Rich*, didn't realise you're from Ponte, that is where I was born :o
