Replace a leaky or clogged sprayer hose and head in fifteen minutes. The trick is getting to the hose connection under the sink.
Use an open-end or basin wrench to unscrew the sprayer hose from the hose nipple. Pull the old sprayer and hose out of the sink grommet. Slide the new hose through the grommet on top of the sink and reconnect it to the faucet.
Hold the base of the sprayer in your hand and twist off the sprayer head. Screw on the new head.
Over time, sink sprayers often break or become clogged with mineral deposits. Or the sprayer hose can harden and crack or wear through from rubbing against something under the sink. The best solution in these cases is replacement. You can pick up just the sprayer head ($5) or a head and hose kit ($10) at a home center or hardware store.
Photo 1 shows how to remove the entire sprayer head and hose assembly. You may be able to get a small open-end wrench up to the sprayer hose nipple, but space is very tight. If there isn't enough room to turn the wrench, you'll have to purchase a basin wrench ($15 to $25 at home centers and hardware stores). If your sprayer hose is in good condition, simply unscrew the head and replace it (Photo 2).
