plumbing question

[johnston]

so my here is my question; on my return I have two 3/4 bulk heads and im using a Neptune core 20 pump with a 3/4 output. so I know I have to tee the line but I cant find a true pvc wye I want to stay with hard pipe and have been told tostay away from hard 90's and tees cause the will cause bubbles in the water column can some one help me out on how you got around this?

Where did you hear about the bubbles? I would say the majority of people don’t have wyes unless it’s a check valve.

wut?

T fittings are fine for return lines. Not for drain lines. You'll want a valve on each leg after the T to balance the flow.

The bigger problem is that a 3/4” output on the COR 20 is going to kill your flow.
