Replacing a Stainless Sink with Porcelain
Install a New Kitchen Sink the Same Size and Shape as the Existing Model to Complete Your Kitchen Overhaul
Finish updating your kitchen by installing a new kitchen sink that suits your preference of stainless steel or enameled porcelain. Choosing a sink model the same size and shape as the original eliminates having to rebuild a portion of the countertop or make special adjustments to the plumbing, but still offers options on finish and drain placement.
Choose a New Sink of the Same Size and Shape
Select the replacement sink, faucets and soap dispenser to fit the existing opening in the countertop and to suit your preference of stainless steel versus enameled porcelain or other composition. An off-center drain can be accommodated by simple plumbing adjustments.
Remove the P-trap and Dishwasher Hose beneath the Kitchen Sink
Switch off the electric circuit breaker that supplies the garbage disposal. Loosen the nuts and remove the P-trap beneath the kitchen sink. Detach the dishwasher wastewater hose from the disposal and catch waste water in a pan.
Loosen and Disconnect the Disposal from the Kitchen Sink
Disconnect the garbage disposal from the sink flange after loosening the retaining ring with a screw driver inserted in the loop provided. Disconnecting the electrical cable should not be necessary.
Detach and Remove the Old Kitchen Sink
Turn off the hot and cold water at the supply valves. Loosen and detach both water lines from the valves under the kitchen sink. Unscrew the clips that secure the old sink to the countertop and lift it out.
Install the Kitchen Sink Flange, Gasket, and Fastening Rings
Apply a roll of plumber's putty to the sink flange. Slip on a fiber gasket, a backup ring, the disposal mounting ring, and a snap ring to hold everything in place. Tighten the assembly and remove any extruded plumber's putty.
Mount the Faucet for the New Kitchen Sink
Set the trim plate on the sink deck and then pass the faucet through. Slip on the mounting bracket and tighten the mounting nut. Insert the sprayer hose, securing it to the discharge tube, and then install the nozzle.
Install the Soap Dispenser on the New Kitchen Sink
Detach the pump assembly and nut from the plastic soap dispenser. Drop the pump through the trim plate and secure it beneath the kitchen sink with the provided washer and nut. Thread the plastic bottle on the pump.
Secure New Water Lines to the Kitchen Sink
Flush the new water lines before attaching them to the new kitchen sink to remove any debris. Add the supply lines to the valves on the faucet and secure them with the attached nuts.
Glue the Kitchen Sink to the Countertop with Silicon
Mark the glue line with masking tape. Squeeze out a generous bead if silicon along the perimeter. Set the kitchen sink in place. Dip your finger in alcohol and running it along the edge to remove excess. Remove the tape.
Reattach the Kitchen Sink Plumbing and Switch on the Breaker
Attach water lines to the valves. Position the disposal and tighten the collar beneath the kitchen sink. Reattach the dishwasher wastewater line and the P-trap. Turn on the water and switch on the electrical breaker to restore power to the disposal.
