Removing the Flange: Step By Step

If you are a bit lost on how to remove the flange from your bathroom sink, don’t worry. This step by step instruction will show you exactly how to remove the flange. It will also show you what to expect during each step and how to handle it. If you follow this guide, you should be able to remove your flange in no time.

Step One

The first step is to look under your sink. In order to perform the removal of the flange, you will need to access the sink from the bottom. To start, make sure that the retaining nut is off. This is in the sink drain basket.

To proceed, you’ll need to use a pair of pliers to remove the securing nut from the basket. One thing that may happen during this step is that the sink drain could spin while removing the nut. If this occurs, simply secure the sink basket or have a helper secure it.

Step Two

For the second step, you will likely need some assistance from another person. You will have to ask them to hold the pliers inside the drain basket. This is to keep the basket there while you go to work on removing the retaining nut. This nut may be rusted on and hard to remove. If it is, spray oil on the threads of the nut and come back in about an hour or two. This should make it easier to remove the nut and complete this step.

Step Three

Now that the nut is removed, you can start the process of removing the flange. This is done by cutting around the edge of the flange. You should use a utility knife to do this. This should free the flange from the putty that holds it into place partially.

Step Four

In this step, you will finally remove the flange from the putty that binds it to the sink. To do this, use a board and place it against the bottom of the sink drain basket. Pound on it lightly with a hammer. This should result in the putty breaking free.

Step Five

For any remnants of the putty that remain, use a putty knife to free the flange around the perimeter of the flange. This should result in the flange being completely free from the sink drain.

Installing a New Sink Drain Flange: Step By Step

Now that you have the sink drain flange removed, you might be wondering what the next step is. You obviously need to replace it. However, many people are unfamiliar with this process. This detailed guide will show you

Step One

The first step to install a new flange is to prepare the new unit. This includes removing the mourning nut and putting in the plastic washer. The steps you will have to take here will depend on the unit that you purchase.

Step Two

The next thing that you will want to do is use a pipe joint compound. This will bind the unit to the sink. Put it on the top side of the washer that you placed in the first step. This will create a tight seal and prevent water from leaking through.

Step Three

Next, you will use plumbers putty to the bottom side of the flange. This also helps to create a seal. Plumber’s putty is a commonly used substance for jobs related to sinks and draining.

Step Four

In this step, you will connect the various components of the drain for installation. Push the flange through the opening in the sink as high as possible. Hand screw in the fixture until ready for final tightening.

Step Five

Once you have the flange in place, you will need to tighten the entire assembly. This will hold it in place and it is now ready to be there for the long-term. Tighten the nut while holding the unit with pliers or by hand. This is done to reduce spinning.

Step Six

The next step is to put the drain stopper in. Push it down into the opening in the sink, where it will rest in place.

Step Seven

This step is to install the lever that will be used to raise and lower the flange. This will be specific to your unit.

Step Eight

Once the lever is in place, the only step that remains is to connect it to the drain. Do this using the designated clip provided with your unit.

Reasons for Flange Becoming Stuck
