I have an existing inground sprinkler system and have an area I would like to add another sprinkler head. The black flexible tubing on the side of my home where I wish to add the new head runs to my front lawn to one of the zones. It is exposed having dug up the area to prepare to seed. The area is roughly 25'x15'. Could I split the black flexible tubing and add a tee to aaccomplish this?
