Okay so I have a 2006 Buick Lacrosse CX and I have a coolant leak I’ve had the thermostat replaced also have had the radiator hoses replaced and the water pump is working perfectly fine had the cooling system flushed still leaking as soon as the coolant goes in it comes right back out not sure why just looking for some guidance on which route to take oh and the elbows are still in good condition

Has anybody done a pressure test?
 
Very easy to do yourself. Most large box auto box stores like Autozone, Advance auto, O'Reilly and others loan the pressure tester out for free. You pay the cost of the tester and they give you a full refund when returned. Also if it leaks out that fast you should be able to see where its coming from

I’ve tried to see where it’s coming from but I can’t get a clear view all I can say is it’s leaking in the front passenger side where the water pump is but again was told the water pump is good
 
You should check it yourself instead of taking someone's word that it's okay. Remove the serpentine belt and check the water pump pulley for excessive play. Like @ulycyc says if it's losing coolant that fast you should be able to see it.
How many miles?

One thing that I like about using the previously mentioned pressure testers is (if there is not much background noise) you can hear the leak when you apply the pressure.
