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.

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.


I had to epoxy two adapters back to back because Valterra does not make what we need.


The product was correct but the shipping didn't arrive when it was supposed to. That could be the fault of our mail system. Thank you for getting it to me as quickly as you did.


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.


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.


Working perfectly. I combined my gray and black water dump systems into one drain port. See before and after photos.


Worked great


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.


The exact part and fit i was needing fast shipping.


This was a tough part to find online. thanks etrailer for making it easier to find than most online sellers. It is a perfect replacement for the original.


Repaired a damaged pipe that was broke from a blowout. This was exactly what I needed.


Just what I needed. fast shipping from eTrailer


Great customer service


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.


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.


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....


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

James S.


great not one problem


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.


Product is excellent! What's even better is etrailer's service. I ordered this item late on a Monday afternoon, it shipped the same day and I received it on the following Thursday. We've been fulltime RVers for over three years and the service was beyond all the dealers I've worked with. Thank you eTrailer!!!


Finally upgraded the plumbing on our 5th wheel. Got rid of the flexible and changed up to 3" schedule 40 black pipe. These fittings worked perfectly. Thanks etrailer.


You shipped fast, but the USPS is another story....


Right parts shipped on time.


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!


I have been in need of this product and was thrilled to locate it at I have installed it and looking forward to using my leak proof sewer connection on our next trip.

The shipping was quick and received it in about a week. Customer service and easy of ordering was 5 stars.


Exactly what I was looking for and very fast delivery

  • 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.

  • 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.

  • 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.

  • What To Do When The Bayonet Lugs Break Off Of The Sewer Fitting
    The lugs of a sewer pipe fitting can not be fixed so you would have to completely replace the fitting. To do that you'll have to first empty out the tank, which since your lug fitting has broken off will require you to hold the hose in place to prevent anything from leaking out on the ground. I highly recommend wearing gloves and glasses as well as a mask to safely get through this process. Once the tank is cleared you can then remove the fitting and replace it with a new one. If you...

  • 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.

  • Recommended RV Sewer Hose for Black Water Tank
    It sounds like you're looking for the parts you need to dump the black water tank on your RV. You should already have a waste valve connection in place with bayonet fittings on it so you will only need a sewer hose like the RhinoFLEX RV Sewer Hose w Swivel Fittings # CAM39761. This hose has a 4 prong bayonet fitting that firmly secures to the RV black-water tank and will allow you to dump your tank. This hose comes with an adapter that will allow you to fit it on 3" slip or 3", 3-1/2" and...

  • Will The Camco RV Sewer Drain Cap # CAM39463 Fit a Portable Sewer Tank With 3" Outlet?
    The Camco RV Sewer Drain Cap # CAM39463 is designed to fit a standard 3" Outlet # T1029-2. This is the standard size and it has the 3" inner diameter you mentioned.

  • 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 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...

  • 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.

  • 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.

  • 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...

  • Recommended Bayonet Flange For Waste Valve
    For the bayonet fitting on your valve, you can use the Valterra Rotating Adapter for Rigid RV Sewer Pipe - 3" Hub to 3" Bayonet - Black Plastic # T1028, the Valterra Adapter for RV Sewer Hose - 3" Bayonet Fitting - Straight - Black # T1024VP, or the Valterra Hose Adapter w/ 3" Swivel Bayonet Fitting - Black # T1024-2VP.

  • 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...
