Step 1 – Remove The Nut Using A Channellock
The first thing you need to do is grab your channellock and remove the nut underneath your sink. Please get a bucket to catch the trap water and prevent the floor from getting wet.
Once again, grab your channellock and remove another nut which is just above the one you removed earlier. This nut can be a bit stubborn, so please feel free to use a hacksaw if channellock doesn’t help.
Now that we have the nut removed, you can remove the strainer basket with ease. This should be rusty and greasy, so please use a pair of gloves if you have.
Once you have removed the basket, you need to clean up this area using a paper towel.
Now that we have finished the clean up, we need to separate the kitchen strainer. First you will be removing the metal lower half of the basket, then the paper ring and the rubber gasket.
Take some plumber’s putty and finger roll it and apply it uniformly to the new kitchen strainer.
Once you have applied the putty, you can place the new kitchen strainer back into the sink and apply little pressure if necessary.
Fix the metal lower half from underneath (the paper ring and the rubber gasket) and tighten it with the brass nut below using pliers or channellock
Using a channellock, make sure that all the nuts are tight and fit snugly in order to avoid any leakage.
Once the nuts are tight, come back up and remove the excess plumber’s putty by hand or by using a paper towel.
After all the hard work, now you only need to run the water from the faucet to make sure that everything works as intended and there are no leaks.
