Searching for Revain found a 3" DWV flange. Haven't looked. they do not claim DWV in their description. I agree with the reviewer that people who sell fittings should list the ID and OD to save a lot of time. There are so many versions of 3 inch pipe, from water to sewer, from metal to PVC. The price was right and if you are sure you need this product then the quality looked good. Looks good in the shopping cart.
