I am a highly skilled and experienced home service professional. I recently completed a job that involved shutting off valves and installing PVC pipe. The job required me to use a variety of tools and techniques to ensure that the job was done correctly and efficiently. First, I began by shutting off the water supply to the affected area. This involved turning off the main water valve located in the basement or utility room. I then used a pipe wrench to loosen the connections on the pipes that were to be shut off. Once the connections were loose, I could remove the pipes from the wall. Next, I installed the new PVC pipe. This involved cutting the pipe to the appropriate length, threading the ends, and using PVC glue to secure the joints. I then used a pipe cutter to cut the pipe to the desired length. Finally, I turned the water supply back on and tested the pipes to ensure that they were working properly. I also cleaned up the work area and disposed of any waste materials properly.
