With the new sprayer fully installed, it's time to check your work. Slowly turn the water supply shutoff valves back on by turning the handles counter-clockwise. Turn on the main faucet to cold, then hot. Pull the sprayer out and press the trigger to divert water through the new hose and head. While the water is spraying, use your flashlight to carefully inspect the quick-connect fitting under the sink for any signs of dripping or leaking. Also check around the mounting nut and the base of the sprayer on the sink deck. Using a dry paper towel to wipe the connection point is an excellent way to reveal even the smallest leak.
Step 1
⏱ 2 min
Prepare the Work Area
Begin by completely clearing out the cabinet underneath your kitchen sink. This will provide you with ample space to work. Place a bucket directly under the area where the sprayer hose connects to the faucet body to catch any residual water. It's also highly recommended to use a flashlight or a headlamp to clearly see the plumbing connections in the dark space. While not always strictly necessary for a sprayer replacement, it is best practice to turn off the hot and cold water supply by turning the handles on the shutoff valves clockwise until they stop.
Step 2
⏱ 2 min
Disconnect the Old Hose from the Faucet
Under the sink, locate the sprayer hose. It is typically a thinner, flexible hose connected to a diverter nipple on the main faucet body. Based on our assumption of a quick-connect fitting, you will need to disengage it. This is usually done by squeezing two tabs on the sides of the connector or by pressing down on a colored collar while simultaneously pulling the hose downward. Pull firmly but gently. The hose should detach from the faucet port. Be prepared for the water trapped in the hose to drain into your bucket.
Step 3
⏱ 2 min
Remove the Sprayer Assembly
Now trace the sprayer hose up to the underside of the sink deck or countertop. You will find a large plastic or brass mounting nut threaded onto the sprayer's base, holding it in place. Using a pair of adjustable or channel-lock pliers, grip the nut and turn it counter-clockwise to loosen it. If it's hard to reach, a basin wrench may be necessary. Once the nut is completely unthreaded and removed, go to the top of the sink and pull the entire sprayer head and hose assembly up and out through the hole.
Step 4
⏱ 2 min
Install the New Sprayer Base and Hose
Before installing the new unit, take a moment to clean the sink surface around the sprayer hole. Take the new sprayer and hose assembly. From the top of the sink, feed the connection end of the new hose down through the hole until the base of the new sprayer is resting flush on the sink deck. From underneath the sink, slide the included rubber or plastic gasket (if provided) over the hose and up against the underside of the sink. Then, thread the new mounting nut onto the sprayer's base shank. Hand-tighten the nut firmly, then use your adjustable pliers to give it an additional quarter-turn to secure it. Ensure the sprayer head is aligned properly on top before the final tightening.
Step 5
⏱ 2 minConnect the New Hose to the Faucet
Take the quick-connect end of the new hose and align it with the diverter port on the faucet body where you removed the old one. Push the connector firmly onto the port until you hear and/or feel a distinct 'click'. This click confirms that the locking mechanism is fully engaged. After connecting, give the hose a gentle but firm tug downwards to ensure it is securely attached and will not pop off under pressure.
