 Low cold water pressure
Author: k9cop (VA)

I had to change all my copper pipe with CPVC going to my kitchen. After I changed all the pipes my cold water pressure is low. hot water no problem, and the pressure is fine in the rest of the house. I thought that I could have a clog. so I replaced the cold side pipes. The only pipe I did not change was the straight one going up through the floor. still pressure is low.

Do you mean the cold water pressure is low at the kitchen sink, nowhere else?

Do you have a shutoff valve below the kitchen sink for the cold water supply line? If so is it fully open (turned on)?

Maybe debris trapped at the outlet of the valve, inlet of the supply line.

That's what I was thinking. Seems odd to go from copper to cpvc, unless the copper was failing in a way they thought more problems would occur.
