What You'll Need

A kitchen sink sprayer can have a leak at several sources due to stress being caused by tight gripping or overextending the hose and so on. At a low cost of $15 (used to purchase a new sprayer and hose assembly) you can repair this problem yourself. Though you can do the repair work without actually turning off the water supply, you need to be careful to not turn on the faucet at a wrong time. Here's how you need to do the job.

Step 1 – Find the Leak

First of all, turn on the faucet and press on the sprayer trigger. Now, carefully check the sprayer head for any signs of a leak. Then, check the plastic coupling which joins the host and the sprayer head for signs of any leak. Third place to look for leakage is under the sink where the faucet is connected to the hose.

Step 2 – Leak at Plastic Coupling

If the leakage is at the plastic coupling, tighten the connection. To do this, firmly grasp the sprayer and turn the coupling clockwise, as much as possible.

Step 3 – Check for Leaks

Now, turn on the faucet and press the trigger again to check if the problem has been fixed. If not, proceed to the next step.

Step 4 – Check the Plastic Sleeve

Turn the plastic coupling counter clockwise to remove the sprayer head. Now, again turn on the water faucet and check the plastic sleeve of the hose for any leaks.

Step 5 – Replace the Hose and Head

If the leak still exists, you would need to replace the sprayer head and the hose.

Step 6 – Check the Washers

Press the washers in the coupling and if you can feel movement, they may have dislocated. If not, proceed further.

Step 7 – Check for Leaks

Put back the coupling, hose and sprayer head. Repeat the first step to check for any leaks. If the problem still exists, detach the plastic coupling and the sprayer head, as earlier.

Step 8 – Replace the Washers

Pry out the washers, present on top of the coupling, using a screwdriver. Press in the new washers, firmly, in place of the old ones.

Step 9 – Check for Leaks

Put back the coupling, hose and sprayer head. Repeat the first step to check for any leaks.

Step 10 – Tighten the Faucet Connection

If the leakage was under the sink, use a wrench to tighten the faucet connection. If the leak still exists, use the wrench to detach the hose and the faucet, in this case you will need to shut off the water supply before you detach the hose.

Step 11 – Dry the Threads

Dry the external and the internal threads of the faucet and hose and use a Teflon tape to wrap around the external threads.

Step 12 – Final Check

Connect the hose and the faucet by first hand screwing them and then using a wrench. If the leak still persists, replace the entire hose and the sprayer.
