Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

Assuming where you are is below 2000' in elevation you can run 2" a max of 32' with 3 90 degree elbows. Each additional 90 deducts 6' from that length. If you go 3" you can go 75' with 5 90's with each additional 90 = 5'
