Oatey GIDDS-173390 43539 Replacement Flange Forcast Iron, 4 Inch, PVC

Watched Ask this Old House, saw my problem and how to fix it, and did it.....

I am currently remodeling my bathroom and had to remove the toilet for the new tile installation. Once the toilet was removed it was revealed to have a old, rusted, and almost broken cast iron flange. It was ready to be replaced. I did my research online and decided to go with this simple replacement rather than call a plumber to install a new cast iron flange which I would assume would cost hundreds of dollars. Once I was able to chisel and hammer out the old cast iron flange, I took a wire brush and cleaned the inside pipe of any rust and debris from it(wear a mask for this part). Once the pipe was cleaned up, this flange slid right into place, no problem. I tightened up the screws that held it place very securely, added my extra large wax ring and installed the toilet with no problem. I also caulked around the base of the toilet for added protection against leaks and any movement of the toilet.

Worked great for the application I was using... Had an old busted cast iron stub surrounded by crumbled concrete, removed old flange which was not the correct one and inserted cup to hold shape while I let new concrete set up (about an hour) then removed cup and inserted Oatey Cast Iron Flange Replacement,... Secured and let concrete finish setting up for a full 7 days before we set toilet due to moister etc.. Now everything has sealed up better than ever! Would defiantly recommend this!

I had a toilet with a lead flange and it was stuck in place; I couldnt remove it. I beat the sides of the flange down and seated this perfectly inside that part.

Life saver. Struggled with replacing the old toilet flange. Made life easy.

We needed to repair a toilet flange attaching to old cast iron system with lead pipe. My local plumber gave me no options but replace all the cast iron pipe, which was several hundred dollars. This flange is designed slip inside the lead pipe and tighten 3 bolts that expand a rubber gasket and seal the connection. Works great, easy to install and saved me hundreds. Highly recommend! Found this method on you tube and then found product on Amazon.

When redoing our bathroom, we needed to replace the toilet flange. This one made it easy to use PVC in the existing cast iron pipe. Time will tell if it does a good job.

This flange grabs the inside of the 4 inch pipe very securely. Sadly for me, the installer did not shim or caulk the toilet. After about a week of use, (toilet pulling side to side on the bolts, which are in the PVC flange, those bolts cracked the flange. I had to remove the Oatey flange, and put a replacement in - i found the Oatey twist and set PVC at local store because i needed it right away. The PVC flange cant handle much torque and should have a steel ring, as many of the PVC flanges do. If toilet is properly shimmed and caulked down, this may not be an issue. But I would say, dont just rely on the bolts in the PVC flange. not enough, and the flange will break.

worked out perfect, make sure you screw it down to the floor before expanding the seal so it dont slip...very nice product...altho I did find it a few dollars cheaper at home depot.

Works well
