I have recently put a kitchen area in my basement. After running the water lines (1/2" cpvc) and installing the faucet, I am only able to get a trickle of either hot or cold water. I disconnected the supply lines from the faucet and it seems like I have good water pressure through the supply lines and through the spray diverter. I have also tried a new faucet and I'm having the same problem. Any advice would be appreciated.
