Features:
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
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.

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.

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.
