Kitchen sink only running with the sprayer
It is hard to be certain without knowing the type of faucet, but if you have the type that has a single lever, it could be 2 things I can think of. If you have seperate knobs, I can only think of one. If you have the type with knobs, take the aerator screen off the end of the faucet, The screen may be plugged with saw cuttings of pvc or what ever type of pipe, or even the water saver orifice may be stopped up. If water runs freely with aerator off, you obviously have a problem there.
If you have the lever type, the ball valve can be in backwards, or even a little way off, and the water can not get to the faucet. I am guessing, the whole faucet assembly MAY be in backwards, but that too can usually be fixed by changing the ball around.
Hope this fixes you up! Read More At : Home...
