We turned off the water supply going outside of the house during winter and we just turn that supply back on but there's no water coming out of the outside faucet. The lever connected to ball valve stem seems to be turning the stem properly and we pull the lever up and down a couple of times but not sure if ball is actually reopening properly. We turned on the drain valve while toggling the lever to see if any water come out, but there's no water coming out of the drain valve. Could something have been dislodged like mineral buildup that blocks the line or the ball valve is broken? Thanks.
