Hey Everyone.

I bought above pump off a member here, but came without instructions. What is the inlet and outlet on this pump?

(PS Looking to buy another and Dual XSPC Top)

The inlet is the one toward the center of the pump and is slightly higher than the outlet which is to the side.

It's a centrifugal pump, so water is fed into the top of the pump and pushed out to the sides.

Thus the outlet should almost always be the lower of the two holes. if they're both on the side.

Easy, the outlet has an arrow pointing outward towards the fitting. Look at the top of the pump.

That's usually good to know from the start. The model would be even more helpful.

Assuming it's an XSPC acrylic top, the center hole on the top is the inlet. The water is then spun in the centrifugal magnet with the impeller and pushed out the side.

Inlet is the tube which leads to the centre, outlet is the other tube.

If you're still unsure, stick some lengths of pipe on each, grab a bucket of water, power up the pump and dip a pipe in the water and see if it sucks the water up. If it sucks, that's the inlet.

This doesn't work since the DDC isn't a self-priming pump. It pushes water, but doesn't suck it up. That's why you need a res feeding it.

The bucket method will work, but the bucket needs to be elevated above the pump and feeding the pump water via gravity.

If you still haven't figured it out post a pic of the pump (would have helped from the start). That way we can see exactly what you are talking about and describe the position of the inlet.

But it really is the one leading to the middle of the impeller (black spinny thing).
