I just purchased a 99-year-old house in April, and water pressure is fine throughout the house, except for from my kitchen faucet, where this is as much volume as I get, regardless of hot/cold
I should also mention that water pressure from the sprayer seems normal; it fills up a glass of water in about 1/4 the time that the faucet does. So, the problem seems to reside between the sprayer diverter and the base of the faucet arm.
Today I finally got up the nerve to shut off the valves in the basement and take the faucet apart, but unfortunately I didn't get very far. The screen at the faucet outlet was fine. I unscrewed the topmost piece of the faucet assembly, everything seems OK here:
Pulled off the faucet, and now I'm stuck, I don't see any way to disassemble further. Nothing will unscrew by hand pressure, and in the interests of not chewing up thread teeth, I haven't applied too much pressure with the pliers yet.
Any suggestions for a next step? Thanks!
