Looking for a leak, I turned off the water supply to the toilet at the shutoff valve behind it. Nothing else was touched , in fact when i went down to see if i may have been sleep-walking or something, the shutoff in the basement wouldn't budge. My problem is that no matter which way i turn the valve behind the toilet i get no water. in fact the silence is deafening. Absolutely nothing happens I'd truly appreciate some input. Thanks.
