Each day if different, it depends upon the job. One day I might install pipe assemblies, fittings, valves, for a dishwashers or water heaters. The next day I will, fill pipes or plumbing fixtures with water or air and observe pressure gauges to detect and locate leaks. I may do pipe cutting, assembly, or installation of new plumbing systems. My day depends upon the job. Each day I check my tools and supplies, work orders and schedule my appointments depending upon the amount of time each project/work order will take.
