Does a home inspector check and test shut-off valves?

Saturday, July 6, 2019

A home inspection is primarily a visual review of a home and the inspector is required to examine the visible, or readily accessible, shut-off valves. What the inspector is not required to do is test the valves, and with good reason. Old or defective valves often leak when opened or closed, sometimes the leaking cannot be stopped by resetting the valve, and older valves are sometimes frozen in position due to corrosion. So the inspector cannot tell you if the valves actually function, but older valves with corrosion should be noted for further evaluation by a plumber—like in the photo above.. 

   The State of Florida’s standards, along with those of the International Association of Certified Home Inspectors (InterNACHI), specifically state that the inspector is not required to test valves. The American Socity of Home Inspectors (ASHI) standards do not directly address the issue, but it is not in the list of required inspection points.

   Inspectors ARE required to describe the location of the main water shut-off and main fuel shut-off valves. This is important to know for emergency use. We make a point of showing the homebuyers where they are if they attend the inspection.
