I mentioned in a previous question that either our pipe burst or our outdoor faucet broke. It leaked into the house. Our main water line is shut off currently. We can't locate a shut off valve to the outside faucet.
The main water line comes into our utility room. It branches off into 3 lines(2 cold and one hot). Is there a chance that one of the colds is for the exterior faucet only? Is there a "typical" scenario?
