I have been in the process of remedying and repairing issues at my daughters house. She just recently sold it and I am working a checklist from the home inspector. He is saying that I have issues with some GFCI outlets that will not respond to his external tester. I am trying to explain to him that a two wire, no ground, old wiring system will not respond to an external tester.
I am trying to find a link or a source to back up my assertion. Anybody have some help?

Anybody have some help? Is the house 100% 2-wire with no gfci's Or is the house half update with some gfci. |

Does a GFI circuit have to have a three-wire circuit to work properly? I have my parents home to worry about as it's older than dirt and was built back in 1951 and only has two-wire circuits.
My house is much more modern with 3 wire circuits and ground fault interrupter circuits around all the areas where water is located.
Now I did have two 3-wire circuits installed. One for my computer in the den area and another in the utility room. There is no ground fault interrupter circuits in my parent's house.
You may have to rewire some of the circuits in the house to get GFI to work. I would call in a certified electrician to inspect the wiring and give you some advice.

I got lucky. My house had the wiring updated from knob and tube to 2 wire but they ran all the wire in metal conduit along with metal boxes (cut into the wall studs behind the baseboards to run the conduit). Easy to ground to the metal box which goes back to the breaker box (that was upgraded to 200a service after I bought the place from the glass screw in fuses) Going to 2 prong w/ground and GFCI meant that I needed to ground to the metal box and I was golden (according to the circuit testers).

esshup is 100% correct and the easiest way to update. Sometimes you have to install a ground outside. I'm not up on the latest codes, but each receptacle needs to run to ground and each area with water needs a GFCI. Bathroom, kitchen, laundry rooms etc.

If you have, which you probably do, metal water pipes you can use those to get your ground. Then a wire from closet pipe to breaker box. Then ground out side with 2 rods 10 feet apart.

Receptacles within 3 feet of a water source has to be GFCI correct? At least that is what I have been told. As what high cotton asked I definitely think 12-2 or 14-2 would be needed thus providing a direct ground to the box with the GFCI, at least that is the way that I've wired some of my circuits that require GFCI.

Yes Or damp locations.
12-2 will be fine for your needs.
