Rated 3.7 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by Easy to install Great product for replacing damaged flanges. This makes a very secure and leak proof attachment for the toilet. Suggest to not only tighten the flange, but to anchor with a two or three screws. We have been using this product for years and are very happy with how well it holds up. December 10, 2013
Rated 1.0 out of 5.0 by Replacement flange failure When remodeling our bathroom from the bones up we discovered we had a broken flange on the cast iron. Hearing there was an easy fix we purchased this item. We placed this part in position and went to install the toilet. I don't know if our installer overtightened or what happened but the "flange" part of this then cracked. Figuring it was a fluke I went out and purchased ANOTHER of these pieces. The install this time went well. Placed the toilet and finished our bathroom remodel. Jump forward 6 months. Go downstairs and notice a white clothing cabinet that happened to be located under the upstairs bathroom is soaked in urine and "other" disgusting fluids. Call my installer. We think maybe a wax ring failed. Nope. This WHOLE unit failed. It had large cracks and hairline cracks all over it. We are not overweight (largest in the house is190). The toilet was installed correctly. I have lost a lot of money as I had to throw away the whole cabinet and all the soaked clothing. This time I got it fixed correct and had a new cast iron flange put on. Please don't waste your money on this item. Do it right the first time. December 4, 2014
Rated 5.0 out of 5.0 by Great for cast iron pipes. Great for cast iron pipes. We had noticed past leakage and the toilet would not seal properly. August 20, 2014
