Upon arrival, customer informed me that his back master bathroom had an issue. He said the shower was draining slowly and would back up if two people took a shower back to back. I asked the customer if anything else in the bathroom was backing up and he said no. I advised customer that I would probably need to snake the shower drain and he agreed. I use the K 45 drill auger to snake the shower drain. I ran 10 feet of cable. After clearing the stoppage I ran the bathroom group for about 20 minutes to make sure the drain had integrity. Customer satisfied..
