Does a home inspector check the water heater?
Thursday, April 30, 2020
Inspecting the water heater is a routine part of any home inspection. The Standards of Practice of both national home inspector associations and the State of Florida require it. The American Society of Home Inspectors (ASHI) states that “the inspector shall inspect water heating equipment and hot water supply systems” and must “describe water heating equipment including energy source(s).”
The International Association of Certified Home Inspectors (InterNACHI) mandate is more specific: “The inspector shall inspect the water heating equipment, including the energy source, venting connections, temperature/pressure-relief (TPR) valves, Watts 210 valves, and seismic bracing.” It also does not require the inspector to light a pilot flame if it is off. Florida inspectors must inspect the “water heating equipment including energy source(s)."
While the Standards of Practice set minimum standards, a home inspector may choose to exceed them, or the inspection may be limited to less than what is outlined in the standards when agreed to by the homebuyer and specified in an inspection agreement. A four-point insurance inspection would be example of a limited inspection.
