    Cut out broken pvc tee and removed fitting. Installed new 3 inch ABS tee. Used 2 no hub bands and torqued them down to 60 psi as per code. Went upstairs to the powder bathroom and ran water in sink for approximately 1 minute to insure there was no more leak. Checked all my fittings and no leak was found.
