text_A: My moms toilet started leaking a few weeks ago. She asked me to try and fix it but I didn't know how. Eventually the leak got even worse to the point of flooding. Her bathroom was flooded daily but we didn't know what to do! After awhile we turned the water off to the toilet and left it.
text_B: I found the water valve ends after we n't know what to do
not-entailment.
