This sewer termination adapter connects your spigot to your sewer hose. 3" Hub slides onto your spigot, and secures with ABS solvent cement (sold separately). 3" Lug fitting allows you to connect to bayonet fitting on sewer hose.
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 RV sewer termination adapter. Now, this part is a black hard plastic construction, has a 3" bayonet fitting on this end and a 3" hub fitting on this end. Now, the 3" hub fitting, that's a female spigot end, it's for gluing ton the pipe, the 3" bayonet end is for connecting your sewer hose or your cap to. Now, the bayonet end, let me give you a few measurements on this. This is going to measure internal diameter of 3". The female end, of the spigot end, inside diameter is 3-1/2".
And the total length on this adapter is 2-1/2". But that should do it for the review on the the Valterra RV sewer termination adapter.

Ratings & Reviews
There is nothing glamorous about buying 3" DWV fittings. But, etrailer made it easy with their great website and helpful videos. Was able to order all the fittings I needed to install a Sani-Con on my fifth wheel.
I was impressed to find BOTH of these unique adapters in stock on your web site. I will now be able to eliminate using my flexible RV sewer hose, with it's drainage issues. These high quality fittings allow me now to hard pipe the drain and achieve assured drainage.
I was very pleased that my order was filled very Promptly. However, using the USPS Priority Mail was a huge mistake on my part - VERY VERY slow activity after the shipping label was created ! It made the "Pony Express" look like a better choice.
I will be very happy to continue to do business with your company in the future. However, I will take advantage of the better shipping options which you offered.
Thanks again George for the quick service on your part and for the follow up e-mail. I appreciate the fact that you and your company care about it's customers.
JUST WHAT I NEED FOR MY PORTABLE BLACK TANK
Hey! This is a great product for those who want to convert there old Thetford sewer set up to the new stuff that is common these days. Our Foretravel motorhome has the old Therford style stuff so I cut the old Thetford adapter off and glued this adapter on using the ABS cement (glue). This old style stuff used ABS plastic pipe and I have been told the Foretravel, AirStream, and Holiday Rambler used this on some of their RVs.
Bottom line, this is a great product for those wanting to convert the old Thetford sewer discharge pipe to the new stuff that is readily available for their RV. Easy to install....
Installed on another Valterra fitting after dealer ground off all the lugs thinking we were wanting to hook up pvc fittings for a park model. Thankfully it worked perfectly.
Worked perfect for my permanent sewer b uild!

Great,would buy again if needed.
These hard-to-find ABS bayonet end fittings for rv sewer lines are essential for anybody doing repairs to an RV or anybody wanting to make hard-line plumbing accessories that require connecting to traditional RV type flex sewer hoses.
Perfect fit, easy to install and fast s hipping.
Installed on a tiny home. It appears to be high quality and works well. Thanks
I had to shorten my drain pipe that connects to the hose where I empty my tanks. They pipe would drag on the ground when parking the camper in my driveway. So, I had to cut off about 6” of the pipe, including the connector the the hose attaches to. I ordered the T1029-2 to replace the one I cut off. It arrived a few days earlier than stated. I was really impressed about that. Glued the the part on , with the proper plumbers glue for that type of pipe material. Works like a charm as if it was from the factory build of camper.
Part arrived quickly and is a perfect fit for the 3” waste pipe in my motorhome. etrailer never fails to provide quality RV products at reasonable prices.

Product has performed flawlessly after a year of use. No failures or complications!
We are using a tote tank as a main black water storage/tote tank on a non-travelling Tiny House. Thus, I had to do a somewhat unconventional hook up. Never having dealt with the RV side of plumbing I was concern I might order incorrect parts.
The product videos on the etrailer site were VERY helpful. Not only did you show the product, you also gave actual measurements that went a long way to ensuring I got the right parts. THANK YOU, Thank You, thank you.
I could not find the plastic pipe adapter from Lowes or Home Depot or any other store. I ordered the part from Etrailer. The price and shipping was less than $x.xx. I receive the part in just a few days. Part worked great , thanks to Etrailer

You're very welcome Anthony, I'm happy we could help you out!!
Great ordering process, they have the parts that the local RV parts sellers do not have, and I got them quickly!
This adapter glued onto the schedule 40 sewer pipe and let me hook up a regular rv sewer pipe
I have a 2025 Winnebago View 24D with cable actuated dump valves, which either don't close and leak or are just very difficult to use..So I replumbed it to like the 2012 24J Winnebago View we traded in on the 2025. New valves are easier to operate and close tightly, looking forward to years of no problems now..been rving for 52 years never had these problems with any other rvs we have owned..Thanks for the parts
