Problem: Your kitchen sink strainers are cracked or worn.
Solution: It's easy to replace kitchen sink strainers.
Equipment list:
plumber's putty
large and medium slip-joint pliers
large and small flat head screwdrivers
safety glasses
Although plastic strainer assemblies are less expensive, they can crack easily under pressure. It's a good idea to use a metal strainer instead.
If you have a garbage disposal, turn off the power at the breaker box before you begin replacing the strainers.
Remove the existing strainers
- Use the slip-joint pliers to loosen the slip nut and free the tailpiece from the drainage system.
- Remove the tailpiece washer.
- From above the sink, use a large screwdriver to disconnect the strainer assembly. Remove the strainer bell from the top, and remove the strainer body from underneath.
Remove the disposal
Check your manufacturer's instructions before removing the disposal.
- Loosen the collar nut on the drain line coming from the disposal.
- Support the disposal with one hand. Remove the disposal from the collar by turning the collar clockwise with a screwdriver.
- Disconnect the collar from the sink by loosening the mounting screws and popping out the locking ring.
- Remove the strainer assembly from the drain hole.
Install the new strainer assembly
- Apply a thick bead of plumber's putty underneath the lip of the new strainer.
- Insert the strainer into the drain hole and firmly press it in place for a good seal.
- From underneath, place a fiber gasket and rubber gasket on the lip of the strainer body. Set the strainer body in place and attach the locking bell and nut.
- Replace the slip nut and washer from the tailpiece.
- Place the new disposal strainer in the drain hole using the same procedure as before.
- Reverse the order of removal to reconnect the disposal. Make sure you get the locking ring and mounting screws in place.
- Wipe off any excess putty and run water through both drains to check for leaks.
