Draining Test

First year in business, trying to make a good impression so I am trying to get the job done quick. Had a water test on a two story house. I forgot to check to make sure I had drained the water from the waste pipes. I pulled the plug on the drain in the kitchen and was welcomed by two stories worth (Duplex Home with combined sewer) )of water as I tried frantically to try and put the cap back on to hold back the stream of water coming from the 1-1/2" pipe. Not only was the water wet but it had been in the pipes a little while. It seemed like forever to dry things out. Luckily I had my shop vac with me. Then I got back to work feeling and smelling great. Nothing like trimming a hot humid house with your whole upper body and side practically dripping wet..
