How to Install Kitchen Sink Clips

property investment

Kitchen sink clips are one of those things that you never think about until you really need them.

They are used to hold your sink securely to the countertop. Although in some cases, it can also be used to hold your kitchen drain pipe in place.

Kitchen sink clips come in many different shapes and sizes. But the processes involved in installing them are almost the same.

Not installing your kitchen sink clips properly can result in your kitchen sink dripping. This can be an annoyance, and if the problem persists for a long time, it can even cause damage to your flooring. 

How to Install Kitchen Sink Clips Properly

Kitchen sink mounting clips installation is a simple DIY project that can be done in just one afternoon, but it could take the entire day without proper planning.

Tools Required

To fit kitchen sink clips, the tools you will need include:

  • A basin wrench (or pliers as an alternative)
  • Adjustable wrenches
  • Screwdriver
  • Hand-gloves
  • Silicone Sealant
  • Sealant gun
  • Razor
  • Alcoholic solvent
  • Paper towel

Step 1: Ensure that you’re using the appropriate type of clips for the sink

To know which type of clips to use for your kitchen sink, check the sink installation instructions if you still have them. When you purchase a new sink, it comes with sink clips and instructions for using them. It’s essential to read the instructions because different manufacturers use different types of clips and design the sinks for those particular clips.

When installing sink clips to an undermount sink or hooking up top-mount sink clips, they may have to be glued or screwed to the countertop, depending on the sink and countertop material.

The instructions will also tell you how many clips you need to use and how far apart to space them. For example, you need fewer clips for a stainless-steel sink than you do for a composite one because stainless steel is so light.

However, if you can’t find the instruction manual, do not worry. Simply take the old clips to the store from which you intend to purchase a new one and request a similar type.

Step 2: Shut off the water supply to the sink

Before proceeding further with any work, the first thing to do is shut off the water supply to the sink. You can do this by simply turning off the main water valve.

If your kitchen has an unusual plumbing setup, you may have to turn off more than one valve before working on your new sink. This will prevent any potential damage that could occur while you are working on it. Also, you may seek help from professional sink plumber to properly set up sink clips.

Step 3: Remove the old sink clips from the faucet

To do this, gently unscrew the faucet handle that has a hole in it. Then, remove any pipe clips holding the pipes onto the tap and disconnect them from each other by unscrewing them a little bit at a time.

Be careful not to lose these pipe clips as they’re hard to find replacements for. Pull off the clips at the end of the faucet stem using pliers or vice grips to grip it tightly.

Step 4: Attach the clips to the sink

Your typical kitchen sink will have a channel at its bottom, which is designed to accommodate a rubber plug. So, the next step is to slide each clip into this channel. The clips are to be hooked on two bars that run across the channel, so you should be able to easily push them in.

This will prevent any water from leaking out of your drain. If you’re using multiple clips, make sure to use enough so that there is no movement whatsoever in the base of your sink!

Step 5: Apply a bead of silicone sealant to the edges of the sink

The purpose of using a silicone sealant is to create a tight, seamless fit between the sink and wall. Be sure that you are using 100% silicone sealant, not a mixture.

Insert the silicone sealant tube into your sealing gun and cut the end of the nozzle down to 1/4 inch wide. Gently squeeze the trigger as you guide it around the sink. Work it around the sink and down between each hole.

Step 6: Placing the clips appropriately and cleaning up

Place the clips, so they are out of the way when you lower the sink onto the counter. Turn the sink over and place it on top of your countertop. Gently press down to secure it in place. You should see some silicone leaking from under the sink at this point. Don’t worry about cleaning this yet as it is normal.

Now, position yourself under the sink. Align the clips so that they are now under the counter. Then, begin to tighten them one bracket at a time with the screwdriver. Alternately tighten one side and then the other until they are tight enough to hold in place.

Wait for at least 24 hours. Then use the razor to cut off any excess silicone. You can dip the razor in an alcoholic solvent to ease cutting through solidified silicone. Wipe away excesses with a paper towel. 

How kitchen sink clips work 

As small as kitchen sink clips are, they are quite essential and perform an important task. They may work by holding your sink securely to the countertop as well as securing your drain pipes in place. Also, they keep your sink from moving around when you put objects on it.

Finally, they prevent the water that is draining from your sink from dripping all over the counter. To tighten the kitchen sink clip, rotate it, so it faces opposite the center. However, you should avoid overtightening it.
