Forum, Has anyone performed the forward flow test through the main drain? I have a light hazard occupancy with 230 gpm system demand. I'm pretty sure I can achieve that with the 2" drain. My question is, do you add a playpipe or any fittings to the 45 on the drain or can you pitot the drain flow as is? What coefficient would you use if not adding a playpipe?
