Kitchen Sink Sprayer is Leaking – Here’s How to Fix


Loose connections and a worn-out hose or head will cause a kitchen sink sprayer to leak. Also, there’s water restriction when dirt, debris, and mineral buildup accumulate in the sprayer’s hose pipe. In return, pressure builds up, cracking the sprayer hose pipe or forcing water to exit via alternative openings like joint points or sprayer holes.

It’s easy to stop a sink sprayer leak—water puddles around the sprayer holes when you start using it. Also, water may dash out from below the sink or spray onto the sink cabinet. The leaking sight is disgusting. So, what do you do? Fix it!

How?

Fortunately, fixing a leaking kitchen sink sprayer isn’t rocket science. You only need to repair or replace the worn-out parts and unclog the pipes using the right tools and procedures. Also, use a reliable water softener if using hard water. In case of drips, use under sink mats to protect your sink cabinet.

This guide will explain different causes of a leaking kitchen sink sprayer and how to fix them through well-illustrated, simple steps.

Fix a leaky Kitchen Sink Sprayer

Why is Your Kitchen Sink Sprayer Leaking?

Probably you’re wondering why we’ve started looking into the causes of sink sprayer leaks instead of discussing the fixing procedure. It’s easy to fix the problem when you understand it.

Sometimes it’s tricky to discover a leaking sink sprayer, especially if the problem is with the connection or the spray hose. Not until you find water rushing out under your sink. But it’s obvious your kitchen sink spray is leaking when you see puddles around its nozzle unit or drips from its head.

But what could have caused the leaking? Kitchen sink sprayer problems result from the following problems;

1. Loose Sink Sprayer Parts

It’s a no-brainer; a loose kitchen sink sprayer connection, nozzle, or head will allow water to pass through. It’s evident when you run the sprayer. You’ll see water dripping from the sprayer’s head, base, or holes. The only solution is to tighten all the unsecured parts.

2. Worn Out Sink Sprayer Parts

A sink sprayer has various parts that can cause a leak when worn out. Parts like washers and worn rings are not durable. The duration of time they serve before requiring replacement depends on the sprayer use.

However, you’ll need to replace them eventually. Otherwise, you’re likely to see water splash out in the sink when using the sprayer. Will you enjoy drying water under your sink after using your sink? It’s not fun!

3. A Damaged Spray Hose

Have you ever run your kitchen sink’s spray and its hose sprayed the cabinet and the entire area with water? That must have been a torn or cracked spray hose.

Most people tend to stretch their kitchen spray’s hose pipes when using the spray. It’s wrong because the overstretching causes it to tear or crack. Fortunately, fixing the kitchen sink sprayer that is leaking through its hose is easy. You only need to replace it with a new one or repair it, as shown in the fixing procedure below.

Another reason a spray hose may leak is when it twists on the point it connects to the faucet. If you discover this problem, align the spray hose by stretching it out.

4. Clogged Drain Pipes

Solid items such as food particles do not dissolve or pass through the trap. Also, some liquids like grease don’t drain easily down the sink, clogging the pipes.

Clogged water pipes do not allow water to flow out easily. When you turn on your kitchen sink sprayer, water builds up on the clogged area, creating pressure. The high pressure may cause the sprayer hose to expand and crack. It also forces water out through nearby openings such as the connection point or the sprayer holes.

Empty your kitchen sink trap and avoid running down thick and greasy liquids. Also, don’t allow large particles to go down your sink. Use chemical dissolving agents or high pressured water through a pipe snake to unclog a blocked water pipe.

5. Mineral Build-Up

Hard water is a common cause of a kitchen sink sprayer leak. Minerals such as calcium build up on the sprayer’s disc, blocking the water flow and creating pressure. In return, the sprayer starts leaking.

Mix household cleaning vinegar and water and soak your sink sprayer’s nozzle in the solution for a few hours to remove all kinds of hard water build-ups. Then run hot water through the sprayer for a while. If it still leaks, disassembles the nozzle and clean it.

Now that you’re aware of what can cause your kitchen sink sprayer to leak, you probably wonder how to sort the problem. How to fix a kitchen sink sprayer that is leaking is a common concern for most homeowners.

If Kitchen Sink Sprayer Hose Leaking

If the sprayer hose is severely damaged, the best option is to replace it with a new one. If not, you can rectify the leaking area. The following procedure makes fixing a kitchen sink sprayer that is leaking from a hose a doddle.  

1. Collect the Required Tools

You cannot undertake the fixing process without the right tools. You have to assemble them before you start. They include;

  • Two clamps
  • Scalper knife
  • Fitting tubing
  • Grease or Vaseline
  • Screwdriver or wrench

2. Secure the Water Supply

After having all the necessary materials for the procedure, turn off the water supply. You can do it from the main supply line or the valve supplying water to your kitchen sink.

Then open the faucet to allow the water in the pipe to flow out. It releases the pressure going into the lines.

3. Cut Out the Leaking Area

Following the closure of the water supply to your sink and draining the water in the pipes, study the leaking area on your kitchen sink’s sprayer hose.

Then take a scalper knife and cut the hose at the center of the leaking area.

4. Insert a Tubing into the Cut Hose

You now have two hose openings after the cut. Before inserting the tubing, put a clamp through each hose opening and secure it lightly above your fixing area. It will help secure the joints after inserting the tubing.

Then apply some grease or Vaseline to the outer side of the tubing. It will facilitate the tube to slide into the hose easily. Also, ensure the tube is long enough to cover the entire leaking area. Otherwise, the left-out part may still leak.

Begin by sliding the tubing inside one of the hose’s cut openings until the point where all the leaking area is covered. Then take the other edge of the cut hose opening and insert the protruding tubing until the non-leaking point. You’ve now joined the cut sprayer hose.

Loosen the clamps on both sides and adjust them close to the joint. Then tighten them using a screwdriver or wrench.

5. Turn the Water Back On

The junction is now complete. Open the water supply and test the sprayer hose by running it. You’ve successfully fixed your leaking sprayer hose if it’s not leaking.

 Suppose the leak happens from another area other than the fixed area, carryout the same procedure. But you’ll need to evaluate if it’s better to install a new sprayer hose or repair multiple places. Installing a new sprayer hose works better when fixing a hose with multiple leaks.

Moen kitchen faucet hose leaking can occur in various parts. Delta faucet sprayer leaks can also happen at quick connects. The repair procedure is easy peasy, as illustrated below;

If Kitchen Sink Sprayer Leaking at Quick Connect

A quick Connect can leak if damaged, improperly installed, or experiencing forceful pressure. This fitting comes with a simple design. It also has the O-ring, Connect, and Connecting Body elements.

The Connecting Body is where the water passes. It’s also the component that holds the fitting together. The Connect secures the fitting. It has teeth that bite on the tube to keep the Quick Connect in place. The O-ring is the watertight seal for the fitting.

With this information, fixing the kitchen sink sprayer that is leaking from Quick Connect is a snap. Use the following procedure;

Assemble the Necessary Tools

It’s the first thing you need to do because you cannot disconnect and put back the Quick Connect fitting without the right tools. You’ll require;

  • Tweezers, a nail file, or a toothpick
  • A new tubing
  • A new O-ring
  • Tube cutter
  • Razorblade

Turn off the Water Supply Source and Take Out the Connect

You’ll need to switch off the water supply first to prevent water from interfering with the process. Afterward, use your fingers to push out the Connect from the Quick Connect fitting’s mouth.

Inspect the Tubing

Eroded tubing or improper installation may cause the Quick Connect to leak. After removing the Connect, inspect its condition and if the tube fits in properly. If not, adjust it to its position. The tube connecting to the Quick Connect should depress the –ring and seal the fitting.

If the tube is worn-out or damaged, it can cause leakage. Remove it and insert a new tubing. Use a tube cutter to cut the damaged tube and insert a new tubing. Align the tube edges using a sharp razor blade. Otherwise, an uneven edge will not tighten the seal well.

Inspect the O-ring

When the tube is in order, check the O-ring. Is it properly installed? Is it damaged or worn out?

The O-ring is a round, flat, thin tool used to seal. Look for a small, sharp, thin tool such as a toothpick, pin, needle, tweezers, or nail file to get it out. Use the tool to loosen the O-ring and drag it out.

Inspect the 0-ring. If it’s okay, know the leaking resulted from improper installation. If damaged or worn out, throw it away.

Install a New O-ring

You don’t have to install a new O-ring if the other one is still in good condition. You only need to install it properly to prevent the leaking.

But if the O-ring was damaged, insert a new one. Ensure you install it properly.

Put Back the Connect

After adjusting the O-ring to seat properly in its place, or you have installed a new one, you can slide back the Connect. You’ll still use your fingers to push it back to its position in the Quick Connect fitting.

Switch On the Water and Test

After reconnecting the quick connect, switch the water source back on. Then run your kitchen sink’s sprayer to see if it’s still leaking. If not, you’ve fixed the leaking Quick Connect!
