Video Transcript for Valterra RV Sewer - Connectors and Fittings - T1029-2 Review

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.

Exactly what I was looking for.


As advertised


Our order was delivered in two days was exactly what we needed and better quality then I expected very pleased will most likely do my business with etrailer from here on


Awesome worked as Described


Didn’t fit pipe had to buy another adap ter


These are the right parts to make our permanent sewer line for our 5th wheel.

Wonderful! Having our RV discharge lines made permanent has been a blessing. Not dealing with awkward sewer hoses in heat and snow is wonderful!

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.


Great product.


Still works for my needs perfect fit


Like always shipping was day before always great doing business with ETRAILER THANK YOU


Adapter fits


Fit perfectly


Bought this to replace existing black water connector that had a broken lug. Replacement was easy. Purchase the abs cement along with this part.


Worked fine.


As described. It well work for me.


Worked as I hoped it would.


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 haven't used it yet, but got the order in record time.


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

great not one problem

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....


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.


The nubs on my sewer hose connector on my fifth-wheel sewer outlet had broken off and a sewer hose could not securely be attached. I found this adapter that fits securely on the sewer outlet and I glued it on with ABS cement and now the sewer hose can be securely attached!

  • Bayonet Termination Lug Fitting for Attaching to Pipe with 3.5 inch Outer Diameter
    Since your current pipe has a 3-1/2 inch outer diameter it most likely has a 3 inch inner diameter (measure this to be sure) which would mean that you'd need a 3 inch spigot to lug fitting adapter like part # T1029-1 as this will slip into the pipe and give you the type standard lug fitting for the standard size bayonets to attach to.

  • 3-Inch RV Plumbing Adapter with Lug and MPT Fittings
    Thanks for clearly describing the RV plumbing fitting you need. For a 3-inch adapter with lugs on one end and male pipe thread (MPT) on the other use part # T1029-4.

  • How Does a Hose Get Glued into Valterra RV Sewer Termination Adapter T1029-2
    When gluing a new spigot or bayonet fitting use ABS glue. There should be plenty of surface area on the hose for the glue to work. You may have to bunch up the hose some if it doesn't have a what is essentially a collar at the end of the hose. If you have to do that then be sure to secure the bunched up hose after the glue has been applied and inserted in the connector so that it doesn't try to unfurl.

  • Bayonet Flange to Attach to RV Waste Valve
    We do have what you are looking for as the part # T1009. This will replace the flange side of your waste valve that you sent in a picture of and give you bayonet fittings you can attach to your sewer lines. It's hard to say but it looks like yours may have been broken off.

  • Holding Tank Fitting 3 Hub Fitting
    The closest match that we have is the Valterra # T1035-2 RV Sewer Elbow. The internal measurement on the spigot end is 3" and is meant for a glued connection rather than a push together connection with an o-ring.

  • Waste Valve Adapter for 1972 Timberline Marquis 21 Travel Trailer
    All of our hoses and fittings are for the standard fit bayonet which is not what you have. You can either use the adapter # T05-2285VP you referenced to adapt the older thetford fittings to the standard bayonet or if you don't want an additional adapter I recommend replacing current fitting with the Valterra RV Sewer Termination Adapter - 3" Lug Fitting to 3" Hub # T1029-2.

  • How to Connect an RV Waste Sewer Hose to a Portable Tote Tank with Threaded Fitting
    I think I'm following you. It sounds like your portable tote tank has a threaded fitting, but your sewer hose has a bayonet fitting like a typical sewer hose. If that is the case, then I have a solution for you, but we don't have a single adapter. Instead, you will want to use fitting # T1029-2 and fitting # 344633703 to make the adapter you need. The non-threaded end of part # 344633703, will fit into the end opposite of the 3 bayonet lugs on part # T1029-2. You will want to use ABS...

  • Will Sewer Hose with Broken Pins Fit Female End of Valterra RV Sewer Termination Adapter T1029-2
    Since your hose still has the connector on it just minus the pins it may or may not fit into adapter # T1029-2. But to be sure you can measure the outer diameter of the end of your hose in question. If it is roughly 3-1/2 inches then it can fit the female end of the adapter which has a 3-1/2 inch opening. Use solvent # A05-0303 to join the pieces. I have also included a link to the hoses we have should you decide to just replace the hose.

  • What Schedule Of Pipe Does Valterra RV Sewer Adapter - Item # T1029-2 Fit
    I contacted the manufacturer and the Valterra RV Sewer Termination Adapter, Item # T1029-2, fits standard ABS sewer pipes for RV uses. It is made from a very sturdy plastic and you would use something like ABS Solvent Cement, Item # A05-0303, to join the pieces.

  • How to Replace Spigot Adapter on RV
    If you need to replace the Valterra RV Sewer Termination Adapter # T1029-1, or a similar connector, then you should be able to cut off your current adapter and then install a new adapter using a coupler like part # D50-2935. Be sure to use Valterra ABS Solvent Cement # A05-0303 to make the connection after cleaning the pipes really well so that you get the best connection possible. If you are uncomfortable with this then I recommend checking in with a local trusted shop to have them do...

  • Semi-Permanent RV Sewer Connections Made To Septic and Fresh Water Supply Needed - 75 Feet
    Your fresh water hose is an easy recommendation, I suggest the Camco RV drinking water hose, 5/8" diameter at 75' Long, # CAM22803. This is a reinforced PVC hose for drinking water made of FDA-approved materials and BPA-free. Because you state that you are new to RV living I will make the suggestion that you also use a water pressure regulator, I suggest the Camco RV Water Pressure Regulator, # CAM40055. Please see the attached video for a visual of product. Because inconsistent water...
