Today, we're going to take a look at the Valterra replacement 4 inch by 3 inch RV toilet floor flange. This replaces the floor flange on your RV toilet. It is a size 4 inch by 3 inch. That measurement, the 4 inch would be the top measurement inside diameter and the 3 inch would be the internal dimension of the bottom threaded section, 3 inches. Now the male, this is a 1.88 inch male threaded part. When you do go to install this, this would go down, screw into your black water system.
Once it's tightened down, then you'll put screws in there to hold it into place and then right in here is where your wax ring will go before you set your toilet down there. That should do it for the review on the Valterra replacement 4 inch by 3 inch RV toilet floor flange.
The threads are to short and it will not snug up with the base. Know I’m stuck with a product that does not work.
This was an exact replacement for the broken floor flange in our 2000 Roadtrek Popular 200. The floor mounting holes and the toilet bowl studs lined up correctly so the toilet sat square to the bathroom floor.
The only problem was the factory didn't pre-drill the floor mounting screws so they would seat squarely in the flange. Most of them were toe nailed in. I think that is what broke the original flange.
The bad holes will be ground out and filled with thickened epoxy. Then pre-drilled so the new screws will be installed without damaging the flange.
Worked as it should
I paid for expedited shipping. The product arrived today; 1 week later. etrailer’s word has no value.

I see that you chose ground shipping. We do not have any specified time frames when it comes to ground shipping. If you are needing an order in a specific time frame, you would need to pay for 3 day or 2 day shipping in order to guarantee a specific delivery date.
Great value, good processing.
Product was what I expected it did arrive two days later than was expected
Fits perfectly, as expected. Super fast shipping. Excellent transaction. Would shop here again and recommend to friends.

Oh no, that’s super frustrating Mike! The T05-0782 flange only has about 7/8" of usable threads, how much longer do you need them to be? I am sorry that we are not able to return plumping parts after they have been installed.
