I am trying to figure out how to figure the lenght of pipe i need to finish a plumbing project.
I am working with 1 1/2 water pipe. I have 2 legs that i want to connect together. The distance between the elbows is 3 feet.
Each leg has an elbow and both are straight opposite of each other.
I want to install a union between the legs.
How much gap is needed between the union halves to properly seal the union?
I know i will need some nipples.
