Single-Handle Cartridge Faucet Diagram A single-handled cartridge faucet is easy to disassemble. Just pry off the decorative cap on the handle, remove the handle screw, tilt the handle back and pull it off. If there's a threaded retaining clip holding the cartridge in place, use needle-nose pliers to remove it, and then pull the cartridge straight up. In Richard's case, only the cartridge needed replacing. If the O-rings are cracked, remove the spout and cut off the old O-rings using a utility knife. After coating the new O-rings with nontoxic, heat-proof plumber's grease, reassemble the unit. Prep the faucet for repair The first task in any faucet repair is to shut off the water feed by closing the valves under the sink; if there are none, Richard shuts the water main. He turns on the faucet to bleed the pipes of water, then plugs the sink's drain with a rag. "The smaller the part," says Richard, "the more it wants to take a dive down the drain." To figure out the next step, "look at the faucet and try to understand how it was put together, then go in reverse," advises Richard.

This single-handled kitchen faucet has a cartridge under the handle. The cartridge has holes that mix the hot and cold water to deliver different temperatures depending on how the handle is turned. If it's worn or cracked, water will seep through to the spout. To remove and replace it, Richard first uncovers it by using a pocket knife to pry off the decorative plastic cap—similar to those on two-handled "hot' and "cold" units—to expose the screw that holds the handle in place. Richard removes the screw; then he gently wiggles the handle back and forth to loosen it and slides it off. The faucet handle isn't the only thing between Richard and the cartridge; he must unscrew the bonnet——being careful not to scratch this chrome cover for the cartridge assembly—with a pair of slip-joint pliers. Then he uses needlenosed pliers to grab the U-shaped retainer clip, which slides through the faucet base and around the cartridge to secure it in place. As he takes out the pieces, he carefully lines them up to the side so he's sure not to lose anything or mix up the order of the parts when it's time to reassemble the faucet.

Richard grips the stem of the exposed cartridge with his pliers. To overcome the suction resistance of the rubber O-rings at the top of the cartridge, he pulls up firmly, sliding the unit straight out without any side-to-side twists. Had the leak been coming from the base of the handle, Richard would have known that the O-rings needed replacing. But since this is a case of a dripping spout, he's already surmised that the cartridge is the problem. He installs a new one, making sure that he places it in the same position as the one he just pulled out, so the holes in its side that deliver the hot and cold water to the spout will not be mixed up.

Open the faucet to drain any excess water. Use a small adjustable wrench to disconnect the hot- and cold-water supply lines from the shutoff valves (Image 2). Using a basin wrench, reach up behind the faucet, and unscrew the coupling nuts connecting the supply tubes to the faucet (figure 1). Use the basin wrench to remove the mounting nuts holding the faucet in place (figure 2). With the mounting nuts disconnected, lift out the old faucet, and use an adjustable wrench to disconnect the sprayer hose from the assembly (figure 3). Lift out the sprayer hose. After the faucet is removed, use a scouring pad to clean the sink surface thoroughly.

If the sprayer-hose escutcheon cap is in good shape, you may want to leave it on. If not, replace it with the one included with the new faucet. Position the New Sprayer Hose Slip the new sprayer hose down through the sprayer hole, and feed it up through the center faucet hole. Use an adjustable wrench to connect the hose to the sprayer nipple. It's time to connect the new faucet's fittings with the water-supply lines. The manufacturer's instructions may direct you to set the new faucet assembly in place, then crawl back under the sink to make the new connections. Save yourself from struggling in cramped quarters by making all the connections you can before setting the new assembly in place. Then feed the connected lines down through the hole in the sink. With the attachments at the base of the faucet assembly already in place, the only work you'll need to do under the sink is to connect the supply lines to the shutoff valves. Attach the Flexible Connectors The hot and cold supply tubes on the faucet may vary in length, depending on the brand.

You may want to attach flexible connectors to adapt the faucet for a particular installation. If so, attach them to the fittings on the faucet's supply tubes. Use two wrenches to tighten each connection -- one to hold the faucet-fitting stationary and one to turn and tighten the female fitting on the flexible connector. This two-wrench technique will help prevent twisting and damaging the faucet's copper supply lines. (Note: Depending on the size of the hole, you may have a tight fit and thus be able to attach only one flexible connector before seating the faucet assembly. In that case, you may need to wait and attach one of them from underneath the sink once the faucet's in place.) Insert and feed the connectors and supply lines into the center hole, and, making sure that the faucet's gasket lines up correctly, seat the faucet (Image 1). From under the sink, install a washer and nut -- or a plastic nut-washer combo (Image 2) -- to the end bolts that will hold the faucet in place.
