Hey everyone. I'm a little bit puzzled by this so I'm hoping someone can help. We have 4 valves under the kitchen sink but only two are hooked up. One seems to be feeding the faucet and the other the fridge for ice. When we shut off the 2 valves water still runs when we turn our faucet on. Another weird thing is when the water was shut off and we turned the faucet to the left for hot the water turned off but you turn it back to the right towards the cold and water flows again and still valves are shut..how is this possible?
