Stop Flushed Paper Nightmares: Here’s How to Remove Toilet Flange Knockout

Are you struggling to remove the toilet flange knockout but don’t know where to start? This comprehensive guide will provide you with a step-by-step walkthrough and tips to help you successfully remove the knockout. Whether you’re a DIY enthusiast or a professional plumber, this guide will empower you with the knowledge and techniques you need to tackle this task.

Safety First

Before beginning, ensure your safety by wearing appropriate protective gear such as gloves and safety glasses. Turn off the water supply to the toilet and flush the toilet to remove any remaining water.

Step 1: Locate the Knockout

The toilet flange knockout is a removable section of the flange that allows for the installation of a closet bolt or a toilet wax ring. It is typically located in the center of the flange and is round or oval in shape.

Step 2: Choose the Right Tool

There are two primary tools used to remove toilet flange knockouts: a knockout punch and a utility knife. A knockout punch is specifically designed for this task and provides a clean and precise cut. A utility knife can also be used, but it requires more care and precision to avoid damaging the flange.

Step 3: Using a Knockout Punch

Align the knockout punch over the knockout. Ensure it is centered and secure. Strike the punch with a hammer or mallet until the knockout is removed.

Step 4: Using a Utility Knife

Score around the knockout using a sharp utility knife. Be careful not to cut too deeply and damage the flange. Once scored, use a screwdriver or pliers to carefully pry out the knockout.

Step 5: Clean the Knockout Area

Once the knockout is removed, clean the area thoroughly. Remove any debris or sealant residue that may interfere with the installation of the toilet.

Step 6: Install the Closet Bolt or Wax Ring

Insert the closet bolt or toilet wax ring into the knockout hole. Ensure it is properly seated and secure.

Step 7: Reinstall the Toilet

Place the toilet over the flange and align the bolt holes or wax ring. Carefully lower the toilet into place and tighten the nuts or bolts to secure it.

Finishing Touches

Reconnect the water supply to the toilet and turn it on. Check for any leaks around the base of the toilet. If there are no leaks, you have successfully removed the toilet flange knockout and installed the toilet.

Additional Tips

• If the knockout is particularly stubborn, you can use a penetrating oil to loosen it up.
• If you are using a utility knife, be sure to use a sharp blade to avoid tearing the flange.
• If the flange is damaged during the removal process, it may need to be replaced.
• If you are not comfortable removing the toilet flange knockout yourself, it is recommended to consult a professional plumber.
