Video Transcript for Feature Review Replacement RV Toilet Floor Flange

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.

Replacement RV Toilet Floor Flange - 3" MPT - T05-0782

Average Customer Rating:  4.6 out of 5 stars   (31 Customer Reviews)

Replaces the floor flange for your RV toilet. 3" Male NPT end threads into your RV's black-water system.

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.

Great value, good processing.

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.

  • Can An RV Toilet Flange Be Replaced Without Ripping Up The Floor
    Hey Tom, I would first see if your flange is screwed on like the # T05-0784 or # T05-0782. If not and it's glued on you can use a rotary tool with a cutting wheel to cut the pipe from the inside out to avoid pulling the floor. Depending on how they sealed the bottom up you might just have corrugated plastic as the bottom of the trailer that you can cut to gain access to the pipe from below and then just patch back closed with zip ties and RTV sealant. If none of these options work then...

    Yes, the Replacement RV Toilet Floor Flange # T05-0782 will work for your Dometic 310 Part-Timer RV Toilet # DOM37FR toilet as these parts are universal. The correct corresponding gasket to work with this, is the Valterra RV Toilet Floor Gasket with Hold Down Bolts # Q23653VP. As far as sealant goes, Valterra recommends to use non-hardening sealant safe for ABS plastic.

  • Which Way Should the Valterra RV Toilet Floor Gasket Be Facing
    Correct, the tapered end of the Valterra RV Toilet Floor Gasket part # Q23653VP should be facing down towards the tank. In regards to the back and forth rocking, this would be hard to diagnose without seeing your particular setup but the issue could be the thickness of the floor flange or the fit of the gasket inside the floor flange in which case you would need the Replacement RV Toilet Floor Flange part # T05-0782 or part # T05-0784 as well as the Valterra RV Toilet Floor Gasket.

  • Should Sealant Be Used On Valterra T05-0782 RV Toilet Floor Flange
    According to Valterra, you should use a non-hardening sealant safe for ABS plastic. Don't use standard pipe dope or teflon tape as the pipe dope will harden over time which can cause leaking. Teflon tape acts as a lubricant, not a sealant. The danger of using that with ABS pipe is that it can cause the installer to over torque the fitting which causes the pipe or fitting to deform which would then very likely leak.

  • Replacement Flange Needed To Switch Out A VacuFlush Toilet For A Dometic 320
    Hey Ted, Is your VacuFlush a four-bolt flange with the bolts more in an x-pattern rather than lined up with a standard toilet flange, like you'd see at your house? If so you can use Dometic's RV Toilet Floor Flange Adapter Kit # DOM73FR to transition back to a two bolt flange and mount the 320 # DOM87FR. If your flange is just broken and in need of replacement then you would want to check how it mounts to the drain pipe. If it screws on then we have ones with internal threads # T05-0784...

  • Are Offset Toilet Floor Flanges Available To Gain More Rough-In Clearance
    Hey Robert, We don't currently offer an offset flange but you could just use a residential floor flange with an offset from your local hardware store. You'll likely have to cut the floor to accommodate the offset. The current flange could be screwed on like # T05-0782 or # T05-0784 (hopefully), but it could also be glued on like # 3446336347 which would require you to cut the drain and would probably need to pick up a couple more fittings to reroute the pipe.

  • How to Remove RV Toilet Floor Flange
    You will need to find a way to twist the flange off as it will be threaded. We have the MPT (Male Pipe Thread) part # T05-0782 and FPT (Female Pipe Thread) # T05-0784 flanges which both are for 3" sewage pipes like what you have on your 1998 Northlander Supreme. If all of the places where the bolts hold the flange down are cracked and broke off when you removed the bolts then you may need to get a little creative. The flange will likely be a bit of a bear to remove so keep that in mind...
