Kitchen sink water pressure

[McVoyagers]

Hi all,
Hope all of you are well. We have a 2016 Newmar Bay Star. The cold water side of the kitchen sink barely trickles out. Pressure in bathroom sink and shower is fine. I see no separate valve. I do see a brass adapter from the plastic tubing to the steel supply line, which I suspect may have an obstruction. Thought I would ask for opinions before I started mesh search. Thanks in advance. Stay Safe.

try removing tge aerator from the end if the faucet first. you may find the screen blocked with particulates.

If it's a single lever faucet and only the cold side has the problem, I suspect the cartridge valve is defective and needs to be replaced. If both hot & cold have low flow, then it could be the aerator screen on the spout.


If you suspect the pigtail that connects the cold side to the supply line, switch the hot and cold supplies and see if the problem moves or stays on the original cold side.
