In the same are two kitchen sinks. Sink number one works great. A couple feet away (in this little church) is sink number two. It has no cold water but hot water works and occasional it will cough and sneeze hot water (from trapped air pockets.) If you're nearby you will be splashed unexpectedly. This sink has a cold/hot valve under the sink. They're open all the way. The water comes from a well and isn't salt treated. Valves get stuck often. It's so stuck that in order to shutoff water, we'd simply cut power to the well pump. How do I unclog the kitchen sink cold water line?
Thanks
