School plumbing repair. The drinking fountain is tied into the drain from a roof head. When we get excessive rain, it backs up into the drinking fountain. There is an existing mop basin line in the same room; we can disconnect the drinking fountain from the storm drain and tie into the sanitation line. The tie-in points are 8’ apart from each other, and there is open access. Disconnect the drinking fountain from the storm drain that keeps backing up in the drinking fountain when it rains. Cap off storm connection with 2” pvc clean out. Cup into 3” cast iron drain and add 3x2 wye and wrap around room to drinking fountain and tie into drinking fountain drain. Added a 2” wye and clean out in run for future rodding. Anchored 2” piping RO cinder block wall with 2” 2 hole straps. Everything ran and tested, and working as it should
