Brian, This would be a cross connection of the potable water system with wastewater. At minimum you would need a 1" air gap. Chris Dorn From: Brian Harris <[email protected]> Sent: Wednesday, August 23, 2023 8:53 AM To: [email protected] Subject: [Sprinklerforum] Roof Drain / Sprinkler Drain
We have a project with standpipes and a basement. All floors above the basement drain through the Standpipe drain and empty at grade. We usually then drain the remaining (basement) section of standpipe through the bottom hose valve. The GC is asking if we can instead drain that last section by tying into the roof drain in the same stairwell that runs outside below grade. Is this a no-no?
