Took a look at 4” cast pool floor drain line from open pipe in pit 50’ to direct drain in pool supply room with x2 tie ins, x1 tie in from floor drain in pump room, and second tie in from x2 floor drains near pool 40’. Also looked at drain line for track around pool 10’ to double wye with cap on back end could not string up double wye. ***Recommended cutting section of track drain bigger to get small camera in track to find outlets
