I am installing four inch sewer line.

45 down two feet, 10 foot run, 45 right turn, 45 down to existing work.

I remember having trouble the last time I did this type work.

Is it best to assemble all parts "cold" no glue before starting to glue?

Is there an easy way to disassemble the above?

I remember comming up a little short and forcing the last fit.

Is it smart to end with a coupling?

Is there a "best way" to start and end an assembly?
