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

This replacement flange did the job! Easy to install, easy to install the toilet on, easily adjustable as well. I recommend.

Saved lots of money flange wasn’t straight

This worked perfectly to fix my (c. 1890, 130 year old) corroded 4 cast iron flange. I measured the inner diameter at about 3.8; I needed to work at it a bit with a chisel and wire brush in a drill to get the rust and scale out, and then it fit right in. The old top of flange was close to flush but just higher than the finished floor; the new top of flange with this installed was about 1/4 or 3/8 above finished floor. The Sani-Seal foam ring Id bought would not fit with this new flange height, but a 1 wax ring worked perfectly.

Installed like it should.

Very good flange, worked very well for my purpose and solid quality, heavy duty. I installed this to an existing lead pipe. The product is described for use with Cast Iron pipe, but I found that it worked very well with the existing old lead pipe. After the 3 inner stainless steel hex screws are tightened the rubber gasket expands and secures into place and seals the flange to the lead pipe. Very simple to install.

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

Cracked due to slightly out of level floor. Kids are potty training, so it gets bumped into at odd angles a lot. I would order again, but only after i found an effective way to lvl the floor a bit more for reducing the stress on the closet bolt connection the pvc ring. metal reinforcement would be nice.

The toilet was clogged and the wax seal was broken in pieces. Be careful not to damage the steel flange that is in the floor. After watching a video, i almost did it. This replacement fits into your existing 4 flange. It makes the opening smaller but it is probably the easiest method to repair the hold downs for the toilet. This product squeezes the rubber between the plastic which expands so the flange seals inside of the 4 metal flange that is in your floor. Using a standard Allen wrench (Make sure you own a standard set of Allen wrenches or know someone that has tools. I used the Korky 6000BP Universal Toilet Wax Free Seal. It comes with hardware, and two dense foam spacers. https://www.amazon.com/dp/B00NOD4R7M/ref=cm_cr_ryp_prd_ttl_sol_10

I have travertine tile installed over the original slab. I DIY and the original iron flange finally rusted through. The original contractor (1968) just chipped away the slab and mortared and grouted to fiil and seal around and under the iron flange. Pretty sloppy work. Removing the original flange was impossible. I scrapped off the rust inside the drainpipe - an easy process with a chisel or screwdriver. I dropped the Oatey Flange, tightened the screws, the Oatey expanded to make a tight waterproof seal inside the drainpipe and everything went perfectly - it literally took me under 10 minutes! I sealed with silicone, dropped on a wax seal, replaced the toilet. PERFECT and FAST. When my other toilets go, this is definitely the only solution.

Exactly what is needed to convert old toilet (1948) to new toilet.
