There
are many types of kitchen sinks available in the market, but the most
popular among them is made of stainless steel. Sinks are easy-to-install,
easy-to-clean, and show less wear and tear than their counterparts. Still, with
age, they occasionally need to be replaced. With a few tools in hand, it is
possible to remove sinks with the least fuss and bother. If there is a cabinet
underneath, you may want to remove its doors so you can make more room for ease
of movement.
Follow
these steps to learn how to remove your old kitchen sink.
Disconnecting Your Sink
1. Assess what type of sink you have. Kitchen
sinks come in 2 basic designs: under-mounted, which are attached to the
countertop from underneath, or drop-ins, which simply drop into the sink
opening in a countertop. There are only slight differences in how you remove
each kind of sink and they will be explained as you go through the steps.
2. Open the cabinet under the sink. Most of your
work will be done here so clean out everything you can from this space. It will
give you more room to move around and more space to place a bucket or your
tools.
3. Put on your protective eyewear and gloves. The
under sink area is small and confined, with lots of pipes and other hazards to
your eyes. This job can also be messy and hard on your hands, so wearing gloves
is a good idea. Remember that wearing personal protective equipment can seem
like headache at times but it could save you from pain and injury in the long
run.
4. Unplug your garbage disposal, if you have one. Electricity
and water don't mix, so unplugging your disposal as soon as possible is a very
good idea. You may even want to turn off the circuit that the disposal was
plugged in to. Go to your home's fuse box and turn off the circuit breaker
controlling the garbage disposal plug.
5. Turn off the water supply to the sink. You
should have two separate valves located below the sink, one for the hot water
and one for the cold water. In some cases, the hot water shut off knob will be
red and the cold water shut off knob will be blue, but this is often not the
case. Either way, turn both of the handles clockwise until they are all the way
off. Double check that they are closed by turning on the water in the sink. A
few drips at first are fine but the flow of water should be gone.
A. If
you still have water coming out, you may need to consult a plumber to change
out your shut off valves or you could do it yourself by following these
B. If
are no water shut off valves under your sink, you will need to locate them
further down your water pipes. Trace the water supply lines as far as you can,
looking for valves where you could shut off the flow of water. If all else
fails, there should be a main water shut off, either where water comes into
your house or at the curb in a meter vault.
6. Disconnect the water supply lines from the underside
of the faucet. Water supply lines that connect to kitchen sinks are most
often flexible plastic tubing that connect on both ends, at the sink and the
water shut off valve, with metal nuts. Because the connection to the sink is
found on the backside of the bottom of the sink, it may be a bit awkward to get
to.
Use an adjustable wrench, channel-locks, or an open-ended wrench to loosen
the nut on the water line, whichever you can most easily get into the space.
Hold the line in place with one hand while you loosen the nut with the other,
so that when it becomes disconnected you can keep the line upright. A bit of
water will still be in the line, so have a bucket handy to pour out the water
trapped in the line.
A. It's
a good idea to spread towels across the bottom of the under-sink cabinet in
order to catch small spills and reduce clean-up time later.
B. If
the connection between your water lines and the sink are totally inaccessible,
you can usually disconnect that lines at the water shut off valves. Remember,
though, that you need to be gentle with the connections at these valves, as
breaking them would send water streaming into your kitchen.
7. Disconnect the drain pipe from the sink. The
drain pipe is connected at the bottom of your sink strainer with a slip nut or
a coupling nut, that connects plastic drain piping to a metal sink strainer.
First loosen the nut that attaches the strainer to the drain pipe with channel
locks or an adjustable wrench. This is usually a plastic nut that can be
loosened by hand, with a bit of strength of course.
When this nut is loose
don't pull the connection apart yet! You will also need to loosen the slip nut
at the far side of the P-trap, which is a distinctive J- or U-shaped span of
pipe in the drain line under the sink. Loosening this nut as well should allow
you to take off the whole piece of piping between the strainer and the far side
of the P-trap without damaging the piping. Remember to keep your bucket handy
to capture spills.
A. If
you have a sink that is mounted underneath the counter you may need to remove
more drain piping in order to have space for the sink to come out. Remove your
drain pipe further past the P-trap, giving space for the sink to be angled out.
Whatever you take out can easily be replaced, as long as you leave at least an
inch of pipe sticking out from the where it enters the under sink area.
B. A
slip nut connection is designed for removal by hand but if you can't get it off
by hand, you may want to wrap a rag around the nut and gently turn the nut with
your channel locks, so that the slip nut doesn't get damaged.
8. Disconnect your garbage disposal, if you have one. First
you will need to disconnect the drain pipe from your disposal. Unscrew the main
connection between the garbage disposal and the drainpipe with a screwdriver.
A. You
may also need to remove the drain line for the dishwasher, if you have one
connected to the drain through your garbage disposal. This is a simple
connection that should be easy to detach with either a screwdriver or wrench,
depending on the fixture.
9. Remove your garbage disposal, if you have one. Some
garbage disposals have a special Allen wrench that unlocks the assembly from
its connection (this should come with your disposal when you buy it). Use one
hand to turn the special wrench counterclockwise and keep your other hand under
the disposal.
Other types of garbage disposal units use snap rings to connect
the disposal to the bottom of the sink. With this connection, one ring is
attached to the bottom of the sink and one ring is attached to the disposal.
Then the two rings have several screws that sandwich them together, which can
simply be loosened and removed when detaching the disposal. Either way, the unit
will come off quickly and you'll need to have a good grip on it so that you're
ready to catch it.
A. In
many cases, a sink with two bowls will have one bowl connected directly to the
drain and one connected directly to a garbage disposal. If this is the case you
will need to remove both connections.
Removing Your Sink
1. Cut through the caulking around your kitchen sink. Use
a utility knife to carefully slice through the sealant along the edges of the
fixture. Be sure not to cut into the countertop if you are going to continue
using it.
2. Detach the sink from the countertop. If you
have an under-mounted sink you will first need to have someone hold the sink up
while you detach it, otherwise it could fall down onto you. For top-mounted
sinks, this step can be done by yourself. Unscrew the metal clips that connect
the sink to the countertop. Use a screwdriver to carefully take off the tiny
clips. These screws may be difficult to access or be a bit rusty, so just take
your time and be patient getting them off.
A. In
order for your helper to hold up an under-mounted sink, remove the strainer
from the sink, allowing them to hold onto the sink through the strainer hole.
The strainer is connected to the sink with a locknut that is located below the
sink. You will need to use large channel locks to loosen the locknut, turning
the locknut clockwise until it is detached. Then simply tap the bottom of the
strainer up and it should pop up and be easily removed from the sink.
3. Reach under the sink and gently push up on the sink
to loosen it. If it doesn't move easily, move from side to side of the sink,
pushing up until the fixture is loosened on all sides. If you are having
trouble getting the sink to detach, and you are worried it may pull off pieced
of your laminate countertop, have a helper gradually cut along the caulking as
you push up on one side of the sink. This should allow you to remove the sink
without accidentally pulling off some of your counter's finish.
4. Pull the sink out of the countertop. Stainless
steel drop-in units are light enough to remove by yourself but older porcelain
sinks can be heavy, so get someone to help you take that type out. Getting
under-mounted sinks out is just a bit trickier. You will need to angle it out
of the cupboard doors, being careful not to damage any cabinet surfaces or
remaining piping.
5. Clean up surfaces and spills. Scrape off any
old caulk or plumber's putty from the countertop with a paint scraper or a
razor blade. Make sure the surface is clean before you begin installing a new
kitchen sink. Also remember to sop up any water that may have come out of the
sink during removal.
