Hot water works but no cold water on single handle faucet
I have a single handle faucet in my bathroom. When I swing the handle to the cold side nothing come out. The hot side works fine. I tried to see if the cold line was clogged. After loosening the nut at the bottom of the line (near the cold water valve), I found it difficult to dislodge the line. The rubber washers were stuck. The plumbing is kind of old and I was afraid I might break something if I applied too much pressure.
Any suggestions/
