I'm in the process of putting in an outdoor bathroom (before I start my pool build next month) and on the outside of the Pool house/Bathroom I'm going to install a shower head to rinse off. I have the Pool house connected to the sewer line but when the inspector came out. I was told I need a drain hooked to the sewer for the outside shower as well. The problem in my opinion is you don't want rain water openly going into the sewer, and my pool is going to slope towards where the shower is. My plumber doesn't understand this either, and has never had to hook to the sewer line in the past. Has anyone else that has an outdoor shower have to connect to there sewer line?
