Low pressure supply line
The hot water pressure to the kitchen sink has gotten worse and worse and is now a little more than a trickle. I'm assuming we have calcification, or something restricting flow in the line. I've pulled off the supply lines at the sink and confirmed that this is not a faucet problem.
Is there anything I can do to clean a line? Can a plumber clean out the line? Or, is this going to require replacing the line?
