Hi, there! Thank you for taking interest in our manifold setup. No, this does not come pre-assembled. This manifold setup is delivered unassembled to minimize damage and to save storage. It is, however, easy to set up and install so you should have no problem with the assembly. Hope this helps. If you're interested, please feel free to click "Add to Cart". Enter your zip code on the next page and you're all set. Also, feel free to visit our Sprinkler Design Center for FREE custom made sprinkler system layouts! Thank you and we hope to see you again here at PlumbersStock.com!
