4 Tips for Replacing Toilet Flange Bolts

A toilet flange is held securely in place by toilet flange bolts. In replacing the toilet, it is in the removal of these bolts where most do-it-yourselfers find the most difficulty. However, there are now many products and methods on the market that makes the task easier than before. Bear in mind though that your situation may differ from another and may require a unique procedure to have the best possible repair.

Preparing for the Task

Before removing your old toilet, make sure that you measure the distance of the wall behind the toilet to the back hold down bolts. This measurement is called a “rough in,” and most toilets were made with a 12” rough in. If there is a variation in your measurement, ask your local toilet store for assistance.

Once you are done with the measurement, the first thing to do is to turn off your water supply. You should then flush the toilet to empty its tank. Hold the trip lever down so that all the water runs out. The remaining water in the tank and bowl can be dried up with a sponge.

Getting to Know Your New Toilet Flange Bolts

Flange bolts come in sets which usually include a plastic washer. If necessary, you can use this plastic washer to hold the flange bolts in place at the correct height. If there is no plastic washer included in your set, you should buy yourself a new washer set. It will save you a lot of time and trouble, and it will just be a tiny cash investment.

Removing the Toilet Flange

Aside from bolts, a toilet flange is also sealed in place by lead, which is the soft metal that you can see between the inner sewer pipe and the outer closet flange. Drill out as much lead as possible and take out any of the remaining metal using a heavy screw driver. If there is a trim cap hiding the bolts, pry each one of them off with a screwdriver. You can then unscrew the bolts. If you have trouble doing it, you can saw them off with a mini hacksaw. Use masking tape on the surrounding area to protect the finish of your bowl. For an extra stubborn toilet flange, you may have to use a chisel and hammer to loosen it. You can even break the remaining flange if you really cannot remove it. Once you have removed the bolts, you can lift the bowl and seat unit. Rock it back and forth to break its seal with the flange and floor.

Replacing the Toilet Flange Bolt

The new flange bolts should be installed into the slots on opposite sides. 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. Use half turns only to ensure that you do not over tighten them and crack the porcelain of your toilet.
