cold water supply line blockage. How do you clear it?
I Have a 1930's house that has a water supply problem in the second floor bathroom. The cold water supply to the sink has a blockage but the bathtub has a good flow. the hot water is fine to both.
I took the on/off valve off of the pipe to make sure it wasn't the valve or the the faucet. With the main water line on that pipe still produces a small trickle. All other
flows in the house are fine. This sink has not been used for many years due to a large crack in it. I decided to replace the sink but now the water flow problem.
What options do I have to try and clear the blockage or am i out of luck and the pipe will have to be replaced. (ripping walls out ect yikes!)
thanks in advance.
