Removing a drop-in kitchen sink is easy, but can turn into a tough task due to some unexpected problems that can arise. You can run into pipe corrosion, nuts that are hard to reach or have barely any access to the fittings. These problems can be a result of exposure to water over a long period of time. This is a do-it-yourself project that can be completed using the tools and the steps below.
Step 1 – Prep Your Working Area
Remove any items that may be under the kitchen sink cabinets. Distinguish the hot water lines from the cold water lines. They should be marked to show hot or cold. If they are not, you can turn on the hot water to see which line warms up then mark that line.
Step 2 – Shutting Off Water Supply
Locate the hot and cold water lines underneath the sink and turn the knobs clockwise by hand. Before doing anything else, make sure the water is completely off. The faucet can be turned on to ensure all water has drained from out of the pipes.
Step 3 – Disconnecting the Water Lines
Look for the nuts that connect the water supply lines to the faucet tubes. It may be necessary to place an empty bucket or large coffee can under this connection to catch any water that may remain in the lines. With an adjustable wrench, hold the upper nuts, and then use the adjustable pliers to loosen the lower nuts. There may be corrosion on the nuts causing them not to loosen easily. Spray lubricant can be used to break up the corrosion. Loosen the nuts at the valve with adjustable pliers to completely remove the water lines.
Step 4 – Remove Sprayer
Loosen up the sprayer hose underneath the faucet or underneath the sprayer handle. There should be connector nuts on both ends of the hose. Adjustable pliers can be used to remove the hose from one end.
Step 5 – Removing the Mounting Nuts
The mounting nuts are located underneath the back end of the drop in sink. The nuts will be a plastic one-piece nut that you can turn by hand or either a metal hex nut over a metal cap. These can be completely removed with adjustable pliers.
Step 6 – Clearing the Work Area
The faucet can now be pulled out of the drop-in sink. It can possibly be stuck from sitting so long; if the sink is stuck apply pressure to the spigot moving it back and forth until it breaks apart. If there is a rubber gasket under the base of the faucet, remove it and clean the entire area around the 3 holes. Clean the water supply connector threads with steel wool. A new drop-in kitchen sink can now be installed.
