A
new sink will improve the look and usability of your kitchen. Fortunately,
installing a new sink isn’t a difficult project. Here’s a quick how-to.
Measure Your Existing Sink
Measuring
your old sink will allow you to identify the location of drains and make the
necessary adjustments during your installation. If your new sink has different
dimensions or drain locations, you’ll likely need to make countertop
adjustments or additions. It’s a good idea to hire a pro to alter your
countertops, especially if you have sensitive materials like stainless, natural
stone or solid surface.
Examine Your Hardware
Decide
if you’re planning to replace your fixtures as well. If so, it’s best to tackle
your hardware replacements during your new sink installation. If
you’re adding new components like soap dispensers or hot water sinks, you may
have to cut additional holes in your sink. Most sink models come with between
one and four pre-drilled holes. You can avoid sink alterations by planning
ahead and selecting a model that has the right amount of holes for your new
fixtures and extra components.
Remove Your Old Sink
Removing
your old sink will require several steps. Here’s a quick guide:
Turn Off Your Water:
Begin by turning off the water supply to your old sink.
Most hot and cold water supplies are below your sink. If you’re unable to find
these valves, shut of your home’s water main. It’s also a good idea to snap a
photo of your pipe and valve configuration before disconnecting your water
lines. This will help you reconnect your water lines after your new sink
installation.
Turn On Your Faucet:
Turn on your sink faucet to relieve the existing water
pressure and drain the main line.
Disconnect Your Supply Lines and Disposal:
Use an adjustable wrench to remove your
supply line connections. Have a bucket nearby to catch any drips. Next, turn
off your disposal’s circuit and unplug it. Disconnect the P-trap and
let it drain. Use the same bucket to catch drainage from your disposal. Remove
your disposal motor according to the manufacturer’s instructions.
Loosen Your Sink:
Locate the clips that hold your sink from underneath. Use a
screwdriver to turn the clips toward the sink bowl. Next, use a razor blade to
cut the caulk around the top of your sink.
Remove the Sink:
Push the sink from below to separate it from your countertops.
If the sink doesn’t move, revisit the caulking with your razor and double check
that all the clips are facing toward the sink’s bowl. Scrape away any grime or
leftover buildup on your countertops with a putty knife.
Install Your New Sink
Adding
your new sink isn’t difficult. Here’s how:
Double Check the Fit:
Place your sink over the hole to ensure it fits. Call a pro
if your sink is under or oversized. Kitchen specialists are able to shim
and adjust your countertops to fit your new sink.
Attach the Clips:
Flip your new countertop over and attach the clips. Ensure
they’re facing toward your sink’s bowl.
Attach the Strainer:
Roll plumbers’ putty into a thin strip and apply it around
the edges of your strainer and drain. Press your strainer into the drain putty
first.
Add the Gaskets:
Place your sink on its side, apply the rubber drain gaskets
and thread your flange. Repeat these steps for any other drains that don’t have
a disposal. Remove any putty pushed through the drain and into the sink bowl.
Install Your Sink:
Screw on your disposal mounting bracket and apply a bead of
silicone caulk around the underside of your sink. Lower your sink onto your
countertops, making sure to position it squarely. Rotate the metal clips toward
your sink bowl to secure it in place.
Seal the Outside of Your Sink:
Apply a bead of silicone caulk around the
outside of your sink. Wipe away any excess with a wet rag.
Attach Your Components:
Reattach your water supply lines and garbage disposal. Attach
any additional fixtures, like soap dispensers or hot water faucets, as well.
Call a pro if you’re unsure how to tackle this task. Fixture installation
mistakes can result in leaks, malfunctions and reduced utility efficiency.
Reconnect Your P-trap:
Screw your P-trap back into place and turn on your sink’s
water and electrical lines.
