Want to get rid of two separate sewer hoses because your camper has two dump ports. These items can make it easy to convert to solid pvc piping to combine two hose connections into one. Makes everything look neater and be more sanitary. All it took me was two item T-1028 and one item T-1029-2 rigid pipe fittings from etrailer to do it. These items are high quality and easy to install, and not expensive at all. All it takes is these adapters and some pvc fittings and a afternoon of easy assembly. Hopefully the pictures show enough to help anyone tackle the change. You'll really be glad you did. By the way, etrailer seemed to be the only place I could find these. But then they always have the best selection, prices and shipping.


Excellent product! I am leaving my trailer at the trailer park on a permanent basis and used the product to attach to the sewers with ABS pipe, so it would be more durable than the flexible hose. After I had glued the pipes together to the adapter, I was able to connect to the park sewers and then the rotating bayonet hooks made it easy to attach the whole assembly to the trailer. Thank-you.

After a year, it works just as well as it did last year.


I bought adapter so that we could go to
Waste Master cam lock system. My RV is still under warranty. So I don't want to change the factory hook up.
This adapter allow me to glue abs pipe to it to glue to Waster Master cam lock
setup. Also rotating hook up is detachable from RV in the event of cam lock hose problems. Then a bayonet style hose can be used to drain tanks.
Also with camlock on the outside of bay
It's easy to hookup. I don't have to get on the ground to reach up to pull hose up to bay floor.


Works as expected, to glue rigid ABS pipe onto a seasonally stationary RV in place of a flexible sewer hose. This item attaches to the RV's sewer outlet like a standard flexible sewer hose would, and then you glue the ABS pipe to the other end of this item. The other end of the ABS then threads into the RV Park's sewer riser.


The 3 inch side for pipe does not really fit a 3 inch pipe it is super lose and requires a lot of quick drying glue to hold the 3 inch pipe in the cupler side

I have pulled some of these and measured them. I do see that the inner fitting of the pipes diameter is 3.50 inches. I have sent some extra measurements to add to our site.


Best $ I’ve ever spent
Was as described
in the pictures & specs
No problem hooking up
Got the job done
Thanks etrailer!!!!!

Jesse R.


A year later an this product is still at it This is a must have thanks again etrailer!


Product works as expected. BUYERS TAKE NOTE! This will only accept schedule 40 pipe! Thin wall schedule 30 drain pipe will not work. Would have been great info to have prior to purchase. Valterra should update their info. Overall great product tho. No fault by eTrailer.


Love this attachment, works as its suppose to and makes it easy for me to disconnect the PVC from the RV at the outlet without having to dismantle the PVC to the ground drain.

I like to backwash my tanks about once a month so this attachment allows me to complete that process easily since I have to remove the PVC for the backwash attachment.

5 stars for me.


I haven't used it yet but it is exactly what is needed to finish hooking up our sewer line to the septic tank we put in, thanks


Worked like champ, solved all my septic issues!
Shipping was very fast!

Collin K.


Still working perfectly! Thanks!


OK got the new fitting today, very excited. Took about 5 minutes to glue my pipes together and boom no more dealing with nasty flex pipe for sewer. The 3" Pvc pipe hooked up.


Works as designed.


Perfect fit for my application, connecting RV bayonet connection to macerator . Good quality, 4 tabs instead of 2 make it more durable.


Works well so far.RV is in a permanent position and was unable to find a product like this locally.Thanks for the quick shipping.



Still working as it should


Great customer service and fast delivery


Fare price,fast shipping


After placing a incorrect order I emailed them and they quickly responded and corrected my issue


Product as described. Good price and fast shipping.


great product, exactly what I needed, already installed and working.


Excellent part is exactly as advertised and the price was right, I will definitely be using you again in the future
Thank you very much


Fast delivery, easy to order, product looks great. Exactly what I needed


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.


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.


Bought this to hard plumb my 5th wheel using 3" pvc and worked great. Etrailer is only place I found the right connector. If you are long term camping, this beats using the flimsy accordion style septic hoses.


Right parts shipped on time.

  • Could Valterra Rotating Adapter for Rigid RV Sewer Pipe Fit Schedule 20 and 40 Sewer Pipe
    There is Schedule 20 and 40 sewer pipe that has an outer diameter of 3-1/2 inches like what the Valterra Rotating Adapter for Rigid RV Sewer Pipe # T1028 is designed to work with so yes it would fit if the size was correct.

  • Does Valterra T1028 Rotating Rigid Pipe Adapter Leak
    Most likely the issue is related to the glue you used for your application. PVC and ABS require different glue types so you should verify that you used the correct glue for your application. If that's not the issue the problem is possibly the wrong size fitting.

    Yes, of course you can insert and glue the Valterra Rotating Adapter for Rigid RV Sewer Pipe, # T1027 if you choose to.

  • Fitting and Adapter for Waste Pump Sewer Pipe
    The Valterra Rotating Adapter for Rigid RV Sewer Pipe - 3" Hub to 3" Bayonet # T1028 is designed to fit onto a 3" waste valve with the bayonet fitting and the 3" hub will slide onto the sewer pipe so you can have your sewer pipe go between this adapter and the pump. There are other adapters, but they are all going to depend on the fittings you have. For example, the Clearview Adapter for RV Sewer Hose # T1026-1 is a clear and has a 45 degree angle, but uses 3" bayonet and lug fittings,...

  • Can the Valterra Rotating Sewer Adapter Be Temporarily Installed
    The Valterra Rotating Adapter for Rigid RV Sewer Pipe part # T1028 is designed to be welded to the end of a 3" ABS sewer pipe. However, if you don't want to permanently attach the sewer pipe to the hub fitting you could most likely just use a gasket maker like part # LT37467 to stop any leaks.

  • Can A 3 Inch Pipe Be Attached to the Valterra Adapter for RV Sewer Hose Part # T1025VP
    The Valterra Adapter for RV Sewer Hose part # T1025VP has a bayonet fitting on one end and then a tapered fitting on the other end. There would be no way to attach a 3" pipe to the tapered fitting but what you could do is combine the Valterra Street DWV Fitting part # D50-2892 and the Valterra Rotating Adapter part # T1028 to provide a bayonet fitting on one end and then a hub fitting on the other which you would then slide a 3" pipe into. Please note, RV's use ABS pipe construction not...

  • 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...

  • Flange and Gasket for Installing RV Toilet
    Though we do not carry either of those parts I can still help you out. What you are going to need - depending on how your hose threads - is either the RV Toilet Floor Flange # T05-0784, which has 3" diameter female pipe threads OR RV Toilet Floor Flange # T05-0782, which has 3" diameter male pipe threads. Additionally you will need the RV Toilet Floor Gasket with Hold Down Bolts # Q23653VP which is a universal design that works with the flange.

  • Parts Needed To Make 1-1/2" Waste Valve With 3" Bayonet Outlet
    I do have a way for you to get what you want, but that's not something that's made. You'll need a few parts: Waste Valve # T1001 Adapter # T1041-1 Bayonet Adapter # T1028 ABS Glue # A05-0303 You mentioned PVC but your 1-1/2" Grey water pipe should be black ABS plastic per RVIA regulations and not PVC however. You'll connect the waste valve to hub end to your existing pipe, the adapter to the other end of the waste valve, and the bayonet adapter to that adapter.

  • 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.

  • Will LaSalle Bristol RV Sewer Termination Adapter Connect to 3" PVC Pipe
    The LaSalle Bristol RV Sewer Termination Adapter # 34466V293B3S is designed to slide into a larger hub like what you see on the end of # T1028 and secured using ABS Solvent Cement # 3447530889. The inner diameter on the hub should be about 3-1/2 inches. If this is what is on the PVC pipe that you mentioned then it will work great. I don't recommend connecting it directly to another 3 inch diameter PVC pipe though, as this might not allow for the best connection even when using a healthy...

    I have a great roof rack option for you. However, with your WingBar Evo Crossbars # TH711520 (black) or # TH711500 (silver), the crossbars will not work with any Yakima components. This is because each crossbar model is designed to fit with specific feet and fit kits made by the same manufacturer.

This is a reinforced PVC hose for drinking water made of FDA-approved materials and BPA-free.
