You need what is called a hub drain. Then route the I.T. to it, leave the appropriate air gap and you're done.
Unfortunately the hub drain also requires other plumbing for keeping the trap primed and the expense of installing one might not be justified for your sprinkler drain. Craig L.

I do have though, a domestic waste pipe near by. I know that NFPA13 does not allow direct connection of the two and I think I understand the reason for this, but can a check valve be put in the test discharge pipe to satisfy the NFPA requirement? Does anyone know of some sort of air gap device or other method to accomplish this? Never faced this situation before. Any suggestions will be greatly appreciated.
