Hi everyone. New to the forums and this is my first post. My problem is that I have a Crane kitchen faucet from 1947(wing type handles style mounted on a "Sunnyday" sink)that keeps losing pressure. I'll turn it on and after about 10 or 15 seconds, the pressure drops to almost nothing. I turn the pressure up more and the same thing happens two or three times until I have the handle turned up almost all the way. It seems to be worse with the hot water side. It won't hold constant pressure. Any help or suggestions would be greatly appreciated. Thanks
