How To Replace A Kitchen Sprayer Hose That's Leaking

Blog

One afternoon you pull out your kitchen sprayer to clean the inside of a large pan—and suddenly there's water dripping all over the floor. Or you suddenly hear water dripping under your sink and, after some careful water leak detection, trace it back to your sprayer hose. Even a small sprayer hose leak can lead to big water puddles.

It might be tempting to fix a leaking sprayer hose with a wrapping of duct tape. But a proper repair doesn't take any advanced plumbing knowledge and it's a relatively quick project to complete.

Things You Need:

  • Sharp kitchen scissors
  • Wrenches, various sizes
  • Pliers
  • Replacement sprayer hose

Step 1: Remove the Old Hose

Turn off the water supply to your kitchen sink.

Clear out the area under your sink so you can fit underneath to remove the old house. There are a couple of ways to find where the hose connects underneath. The easiest way is to have a friend or family member shake the sprayer above the sink so that the hose line jiggles.

Trace the line to where it originates. It will connect to the sink plumbing with a large brass nut. Before you do anything with that nut, you want to shorten the hose so you don't have to fight with its full length while you work. Use a sharp pair of kitchen shears and snip the hose a few inches away from that nut connection.

You don't want to actually remove that nut. Instead, you want to unscrew the hose from the nut. Use a large wrench to hold the nut in place and a smaller wrench to unscrew the hose.

Step 2: Remove the Hose from the Sprayer

Most replacement hoses come with a new sprayer head. If you want to use that new head, you can simply pull the old sprayer out of its hole until all of the hose has come out, too. You can then dispose of both the sprayer head and all of the old hose bits.

If you want to keep your old sprayer head, it's simple to remove the old hose from the head. Find the locknut at the bottom of the spray head assembly. Twist the locknut until the head loosens up. Pull off the head.

Remove the washer or washers on top of the locknut. Set those aside for safekeeping. Use a small pair of pliers to remove the c-clip that's around the hose end inside the locknut. Set the c-clip aside. Pull off the locknut, set it aside, and then throw away the hose.

Step 3: Replacing the Hose

Feed the hose down through the sprayer hole in the top of your sink. Place the other end somewhere it won't also fall down the hole, such as wrapped around the faucet or under a heavy dish.

Attach the threaded hose end to that brass nut under the sink. You can start the process off by using your hand to screw the hose until you can't turn it anymore. Use a small wrench to finish things off with one or two twists to make sure the connection is tight.

Switch the water supply back on. Remove the hose end from under the dish or around the faucet. Point the open end down into the sink then turn on the faucet. If a steady stream of water shoots out the hose hole, you hooked things up correctly. But you still want to check under the sink for any potential leaks while the water is running. If the hose is leaking near the nut, tighten the hose up more and try again.

You can now replace the old sprayer head or install the new one.

For larger leaks and more complicated projects, don't hesitate to call a company like Emergency Response Plumbing & Drain.
