Re: Leaking toilet or Leaking pipe
very odd to have the inspector say it may be from the fridge and the owner say it's the toilet -- unless the two are back to back upstairs it would seem from the basement you would be able to tell where to investigate depending what's above that spot in the basement.
If it is from the toilet area it would be a good idea to check the underside of the subfloor for rot --- providing the subfloor is visable form the basement. Otherwise, you could end up with a major repair of the floor --- or an unexpected bathroom remodel.
If the rest of the house checks fine then make a condition in your offer to have the leak fixed by a professional plumber ( receipt of proof ).
