A rule of thumb is that a typical plumbing inspection should take about 3 hours. The amount of time the plumbing inspector will be at your home or business depends on a few things. The size of your property and the specifics of what needs checking—especially if we’re looking into things like your sewer line—can influence the time spent doing the inspection.
If the inspector discovers any issues along the way, that might add a bit more time to the clock. While it’s not an exact science, planning for around 2-3 hours in your schedule should be a good ballpark.
