In Texas we are experiencing cold weather causing freezing temp. I did all I was suppose to do, kept cabinet doors open for heat to circulate, covered exposed pipes from outside home. Left all faucets running last night. When morning came I turned on kitchen faucet it spitted out rust, and then ran clear but pressure is extremely low. Left faucet fully open to high pressure in case later on in the day it would get back to normal, went on my lunch break to check it, still the same. What does this mean? All other faucets have normal pressure and hot water is working fine. Is this a pipe breakage or just freezing in the piping in this area of the kitchen? Help!
