New Sprinkler drops in existing System: Please read
(OP)
My building just recently went through a fire inspection in which some some sprinkler heads are run off 1/2" pipe. I must replace this with 1" pipe and then use a 1" x 1/2" reducer for the sprinkler head. However the inspector tells me that I must replace the 1" x 1" x 1/2" Tee with a 1" x 1" x 1" Tee so that the sprinkler pipe is no longer on 1/2" pipe. The sprinkler system is existing and for me to replace the Tees would mean that I would have to remove the piping to get at the Tee for replacement. What can I do to replace the Tees? Is there a pipe fitting where I can tap into the existing pipe and run my sprinkler drops from there? Pipe sizes run from 6" to 1".

That being said I do not believe it is a very good practice and I do not allow it on my projects. Read the appendix material in NFPA 13 for additional clarification of the intent of this section of NFPA 13.

As for mechanical tees on smaller pipe sizes the smallest I am aware of is 1-1/4". This is a victaulic snap-let product. Check out the following link:
