Tenet stated kitchen sink and washer drain is not working Found kitchen sink drain line backing up due to old cast iron piping. Disassembled ptrap and ran pistol snake to clear.

Need to replace the ptrap from the hub to the washer box and bust out blocking to replace the drain line all the way to the washer box to insure there are no more issues Job is not completed Estimates ready to send
