4 Easy Steps for Replacing Toilet Flange Bolts: A Comprehensive Guide

The process of replacing a toilet flange and the bolts that secure it in place can be a difficult task. When done properly though, it can help keep your plumbing system functioning for years to come. If you’re tackling this job, here are four tips to make the process easier:

1. Measure the Rough-In: Before you start the job, measure the distance from the wall behind the toilet to the toilet flange bolts. This is referred to as a “rough-in” measurement and is usually 12 inches. If your rough-in is a different size, ask your local toilet store for assistance.

2. Turn Off the Water Supply: Once you have the correct measurement, turn off the water supply and flush the toilet to empty the tank. Hold the trip lever down so that all the water is flushed out and dry the remaining water with a sponge.

3. Remove Trim Caps: If there are trim caps hiding the bolts, pry each of them off with a screwdriver. You can then unscrew the bolts. If they won’t unscrew, you can saw them off with a mini hacksaw, using masking tape on the surrounding area to protect the finish of your bowl.

4. Remove Lead: Some toilet flanges are sealed in place by lead, which is a soft metal visible between the inner sewer pipe and the outer closet flange. To remove this, you’ll need to drill out as much lead as possible and then remove any of the remaining metal with a heavy screw driver.

Once you’ve collected the necessary parts and tools, you’re ready to begin the replacement process. Place the new flange bolts into the slots on opposite sides and install the toilet bowl over the flange and bolts, letting it drop exactly in place. Put the washers over the flange bolts and hand tighten them using a wrench. Make sure to only turn the bolts in half turns to ensure that you don’t over tight them and crack the porcelain of your toilet.

Replacing toilet flange bolts does not have to be a difficult task. With the right tools and instructions, you can be done in no time. To make sure your new toilet flange bolts are secure, check the parts regularly to make sure they remain tight. Regular inspection and maintenance can help avoid future repairs and guarantee the success of your project.
