Replacing the kitchen sink is a project that will require the removal of the kitchen mixer tap from the old sink basin. Begin by clearing a path to provide access to the water supply pipes and kitchen mixer tap fixture connections. Then, remove the kitchen mixer tap. The homeowner can perform the necessary work in 30 minutes or less with a few tools that are readily available at a local hardware store or home centre.
Turn off the water supply to the kitchen mixer tap.
Open the kitchen mixer tap to relieve any residual pressure in the water supply lines.
Disconnect the cold water supply line fitting on the right side leading to the kitchen mixer tap by using the adjustable wrench. Turn the fitting in a counterclockwise direction to disconnect. Support the water supply line with the lockjaw pliers if necessary to avoid twisting as the adjustable wrench is turning.
Disconnect the hot water supply line fitting on the left side leading to the kitchen mixer tap by using the adjustable wrench. Turn the fitting counterclockwise to disconnect. Support the water supply line with the lockjaw pliers if necessary to avoid twisting as the adjustable wrench is turning.
Disconnect the sprayer hose from the underside of the kitchen mixer tap if applicable and pull the hose out from the sink top.
Remove the sprayer nozzle seat from the sink top by using the basin wrench under the sink. Turn the sprayer nozzle seat-retaining nut counterclockwise to remove.
Remove the kitchen mixer tap fixture retaining nuts from the underside of the sink using the basin wrench. Turn the retaining nuts counterclockwise to remove.
Wiggle the spout of the kitchen-mixing tap to loosen it from the surface of the sink.
Pull the kitchen mixer tap straight up and out of the sink top.
Many kitchen mixer taps are installed using plumber's putty as an additional sealant between the base of the fixture and the sink top. This is why a wiggling action at the spout will loosen the fixture for removal.
