Figured I had nothing to lose but a couple gallons of hot water if it

didn't worked so I tried it.

About half a gallon in, the water apparently hit a certain height

and the toilet flushed itself. I am guessing due to the weight of the

water triggering the flush. So, does this change the diagnosis and

possibly the treatment.

Hers is a two story house and I have vertigo so climbing up on the

roof really isn't an option.

I agree with your suspicion that it's a venting problem. I don't
see how a blockage could cause the toilet to later drain itself.
Also, never heard about the hot water fix either.
