Coolant leaking after Water Pump and Valley Pan replacement

Coolant is leaking from both the water pump and the rear of the engine after I replaced the valley pan gasket and water pump. This is only happening while the car is on (after the coolant starts circulating) and for a couple minutes after the car is off. I did also replace the o-rings for pipes (2 rear, 2 front). I lubricated the o-rings prior to putting the pipes back on and the slid right into place. I also torqued all bolts to spec. I am unable to see the origin of the leak from the rear but the front leak seems to be coming from the water pump gasket. Is there something I am missing? Coolant is streaming out not dripping.

I will follow this thread since my mechanic stated my coolant is leaking and the water pump needs to be changed to fix this leak.
