Video Transcript for In-Depth Review of the Valterra RV Toilet Floor Gasket with Hold Down Bolts
Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a look at this Valterra RV toilet floor gasket with hold down bolts. Now, this 9/16 of an inch RV toilet floor gasket is going to sit within your toilet floor flange. Now, this is designed to be used with the replacement three-inch male or female pipe thread RV toilet floor flanges that you see there on your screen. I am including our item numbers to the male and female pipe thread flanges.
So, whatever one that you are needing, just take the item number that you see on the screen, put it in the search field of our website here at etrailer.com and it will take you to that flange that you need. The universal design of this gasket is going to work well with all types of RV toilets. And let me pull out my ruler here and just give you some overall measurements to make sure that this is going to fit your application. So, looking at the outer diameter first, we are sitting right at 4 3/4 inches. And then looking at the inner diameter, we're sitting right at 3 1/4 inches.
And then the height, we are sitting right at 3/4 of an inch. And the sponge rubber construction is going to give you a long-term seal. Now, as I mentioned and as you noticed, the hold down bolts and nuts are included for your toilet base along with a small sheet here of instructions for the installation process. That's gonna conclude our look today. I do hope that it was helpful for you.
Again, my name is Andy. Thank you for joining me..

I replaced a high profile Thetford Aqua-Magic which was 8 years old and original equipment in my toy hauler. The seal in the bowl was leaking so first I tried to replace the gasket and that did not fix it. This Dometic 320 is a bit larger and about 1/2" higher, but it fit. The first toilet I received was broken in pieces. It even had the word "BROKEN" written on top of the sealed box when I received it. I suspect it was shipped that way and didn't break during shipment. I contacted Amy J. at etrailer.com and sent pictures of the demolished toilet. She quickly approved a new one to be shipped and sent instructions on return of the broken one. I simply boxed it up and UPS came by and picked it up. The Dometic piping arrangement did not match the original installation so I easily installed a 1/2" Shark Bite X 1/2" MIP adapter on the 1/2" PEX water supply. The connection to the toilet is 1/2" MIP. Therefore, I got a long (18" to 24") flexible stainless steel "supply tube" with 1/2" FIP connections on both ends to finish the water supply. All of these fittings are available in the plumbing department of Home Depot. You may have to look intently for the "supply tube" with the 1/2" FIP connections, but they are available. While I was satisfied with my Thetford unit before the bowl seal failed this Dometic is clearly a superior unit and I am extremely happy with etrailer.com.

Very sturdy, well built and quiet. Works very well, It did develop a leak after a year of use, which ended up being the flush valve, it was a cheap and easy repair, even bought a spare to carry with us.

Fit nice and snug. Had to push down on the toilet for a nice tight seal. Didn't have that with my old gasket and that's why I had a leak.

Since you don't have the extra space you would need to stick with a 300 series with either the White # DOM64FR...

- What Kind of Sealant Should Be Used When Installing the Replacement RV Toilet Floor FlangeAccording to Valterra, you should use a non-hardening sealant safe for ABS plastic for the Replacement RV Toilet Floor Flange # T05-0784.

As far as installation is concerned, you will want to screw the Replacement RV Toilet Floor Flange # T05-0784 on until it is tight. I also recommend picking up the Valterra RV Toilet Floor...
