How to Inspect the Main Water Shut-Off Device (UPDATED 9/14/17)
When the inspector is in the basement or crawlspace the main water shut-off should be located. Most of the time this will be located in the basement or the crawlspace towards the front of the home where the street would be located. This won’t always be the case and sometimes you will need to search in other areas of the home. Also, it is important to use your hands when inspecting the main water shut off to ensure there are no leaks on the handle.

No tools required to inspect the main water supply shut-off valve
- Locate the main water shut-off valve for the property. This is usually in the basement or the crawlspace at the front of the property facing the street.
- If the basement is finished check in the mechanical room or for access panels in the walls and behind furniture.
- Once located inspect the shut-off valve looking for any signs of corrosion or leaks. Touch the valve, surrounding pipe, and the valve stem, feeling for any leaks. Do not turn the valve on or off. Turning the valve on or off could damage the bushing and cause it to start leaking, it could break and flood the basement, and if turned on and there is a leak, then you are liable for damage to the property.
- Once the shut-off valve is located go to the section in the program and it will ask for the color/type/location of the valve. Next, the program will require two pictures of the shut- off valve. The first picture is a close-up of the valve and the second is showing where the valve is located.
- Main shut-off piping is leaking, corroded, not present, or damaged.
- Main shut-off knob is missing or damaged.
- Not taking the time to locate the main shut-off valve.
- Not feeling the main shut-off valve for leaks or cracks. (Use your hand)
