I just hooked up the water line from my fridge to the cold water pipe underneathe the house that leads to the kitchen faucet and for some reason now there is about a 50% loss in pressure for both the hot and cold from the kitchen faucet. Everything else in the house runs fine. I checked my work for any leaks and made sure the valves were completely open. I also took off the valve stem on the kitchen faucet to check for debri but none was found. I can understand doing something to lose pressure from the cold water line but from both? I’m lost. Someone please help.
Turn off water under sink and take supply pipe loose and see if you have lots of water there, if you have then you might have got something in spout are the deverter valve is sticking, check it out let me know. What kind of pipe did you connect too, really sounds like something in your faucet.
