Remove cast iron toilet flanges and replace with plastic ones. Learn how to update your toilet parts in these free bathroom repair videos from a hardware expert.
This plastic closet flange here that we worked on is intact. This building was built in 1999, so it's still in good shape. When you're in your older home, you're going to see a lot of cast iron closet flanges, such as this one, and you're going to find that this cast iron is very brittle. If the bolts were ever tightened at a prior date, or if someone bounced on it, or broke it one way or another, this flange could be partially broken. If it's partially broken, there's a product called the flange saver that you can put the closet bolt in, and slide the flange saver underneath, and with the bolt sticking up, when you install the toilet that will spread the force out on what is left of the flange. And that's one way to save a broken closet flange. Say this flange is broken beyond repair. Both sides are gone, and it's loose. Then we have a plastic J-Tech flange that actually will go down inside the hole with three Phillips or Allen head screws, and what happens is we slide it down in the hole, and when we tighten those screws, you'll see this rubber will pucker, and it will seal; make us a watertight seal under that flange. And this is one heck of an easy way to save a broken closet flange, and yet the waste is still forced to go past the flange, down the pipe, so there is very little chance of having any kind of a leak. These two repairs are two easy ways to repair a broken closet flange.
