RGLYONSJR - hi, if you had dirt/grime clogging up the faucet, it's very likely you got some of the same stuff up into the sprayer. Anything that came loose and fell into the water supply line would be able to feed up into the sprayer tube, since both feed from the same water supply line. You may need to disconnect the sprayer feed line from the faucet and see about cleaning it out. I'm not sure how you'd do that, so hopefully one of the expert plumbers (which I'm not) can give you a tip or trick to try. The only other thought that comes to mind is when you reassembled the faucet, something may have blocked the sprayer feed line. I don't know if you can insert the lever ball mechanism backwards or not, but I know the slots cut into the ball have to line up properly. Good luck! Jim D/West Point, VA

Often times its not the sprayer itself, but the diverter inside the faucet. Each faucet (almost every manufacturer) has a diverter inside the body of the faucet which is replaceable. This diverter senses the change in pressure created when you pull the handle on the sprayer and diverts the water to the sprayer. When it becomes clogged with dirt and debris, it will no longer function. Sometimes removing it and cleaning it out will solve the problem, other times, you have to replace it. They are not very expensive. Unfortunately, they are typically under the faucet spout, inside the body of the faucet. On some single lever Delta And Moen faucets (and knockoffs) its under a cap below the handle. Other faucets you actually have to remove the spout to access the diverter, which will be in a little depression in the side of the brass body.

Good Luck
