Toilet move

Hi, My plumber roughed in my toilet piping before I completed the space due to a scheduling conflict. The problem I have is that I'm an inch and a half off of center of the toilet stall. I can access the plumbing from the basement. My question is; Can I extend the pvc by cutting the main line and inserting a coupler? Is there actually some kind of piece that I can insert on the cut pipe to extend it the 1 1/2"?

Thanks

Basically, that would be the way to do it, however just a coupler would not add that much length. You likely will have to use 2 couplers and a short piece of pipe cut to the length needed.

length

couplers do NOT add length. They just let you insert the piece to make it longer, and then usually use two couplings.

thanks guys.
