Is a 90 on the pump intake ok?

post #1 of 4
Thread Starter 
I'm having a tough time trying to keep my water line and pump below my reservoir. it would be a lot easier if i could just have a 90 on the intake but would that effect performance?

I'm not worried about water pressure, more so if the pump will receive ample water so it doesn't create bubbles.

In a closed loop system, all pressure exerts outward at the same pressure, regardless of location. So, no, but not using a 90 in your loop will benefit

At the velocities encountered in a PC WC system, it is unlikely that there will be any issue with have a 90º fitting on the pump inlet.
Many stock and high performance after market pump tops even have an internal 90 at the inlet to the pump.

I'm glad this is not true, or my whole industry wouldn't exist, and modern society as we know it would not be possible because there would be no refrigeration or air conditioning.

In a closed loop system, the flow will be the same at all points in the system, but every component in the system causes static pressure losses, even the tubing and fittings, so the pressure will be different at different points. Obviously the biggest pressure drops will be at the water blocks.
