I’m wondering how you irrigate a green roof as far as getting the water up there and where the best place to put the valve is. I have two four-story green roof projects, and I have the MEC bringing copper pipe supply for irrigation up to the roof. I would think to get the diaphragm to actuate you need to get the valve up on the roof so the pressure isn’t an issue (and you’re not having to run a bunch of lines up for multiple systems)? Would the wire then have to run back down through the building to the controller? Has anyone used a wireless valve in this situation? Owners want only one controller in both projects. I’ve only dealt with one-story green roofs and had the valve on the ground, so this stuff wasn’t an issue. If anybody would be willing to share how they dealt with this, I’d appreciate it. In one case I’m dealing with recycled water, and in the other it’s potable required to have a separate connection from the building potable by the local water district. Thank you!!!!
