I am in the process of adding a bathroom to my basement. The bathroom is near where a former homeowner had a sink. I converted the cold/hot water leads into PEX and am running that for the plumbing. The leads are T'd off of the water lines running to my kitchen sink.
The hot water pressure is fine, however, the cold water has low pressure. There is no build-up in the PEX lines, and it would be difficult to check the T connection (but I could if necessary) for buildup. Is that the only way to fix this? I have no water pressure issues anywhere else in the entire house.
