Removing An Old Sink
Like many plumbing projects, removing the old sink can be the toughest part of a replacement job. Fittings may be rusted or fused tightly, and getting around under the counter can be tricky. If it is a cast-iron sink, it will be very heavy, so make sure there is someone else to help you.
Before you begin, make sure the new fixture will fit properly into the old hole.
Turn off the water supply valves to the hot and cold water faucets. Place a bucket beneath the drain trap. Loosen the slip nuts and remove the trap. Support the bottom of the trap with your hand while loosening the nuts.
Remove the bucket and place a shallow tray or rags underneath the sink supply lines to catch remaining water.
Remove the coupling nuts connecting the supply tube to the faucet tailpiece.
Disconnect additional plumbing for disposers, dishwashers, and sink sprayers.
Slice through the caulking around the rim using a utility knife.
Lift the sink from the countertop using drain hole as a handhold.
Look from water damage to the countertop and clean any excess caulking around the rim before you
install the new sink.
Then call you local waste removal service for instruction on disposing the old sink.
