Which is hot and which is cold

[Carvona]

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?

This possibly sounds like you have a crossed hot/cold line somewhere, or the stop isn't totally shutting off. Has the place been repiped?

A mixing valve such as a kitchen sink valve. will let cold into the hot side and hot into the cold side of the valve

it is mixing, thats what they do

so when you turn on the cold handle, water will come out of the hot side if it is not hooked up

if you want to find out what is going on. unhook the faucet. get a bucket, turn on each valve one at a time

verify what is coming out.or where they go. hot ? cold ? filtered? ice maker? dish washer ? instahot ?

hook a supply tube to the valve, blow air, see where it goes

I have no idea I just purchased the home 3 months ago.

Looks like the 4 stop angles are:
1- cold supply for faucet.
1- hot supply for same faucet.
1- cold for refrigerator or ice maker.
And the last one hot for dishwasher.
Do you have hot and cold water in your kitchen faucet?
