Installation was a breeze. I purchased a 2ft section of 3" & 1-1/2" ABS pipe, two 1-1/2" right angle, one 1-1/2"coupler and one 3" coupler, cleaner (MEK/Acetone) and ABS cement. I cut all pieces first fitted them all first before gluing. Prepared all sections with cleaner first before applying ABS cement. Pictures show the "before" with duct tape in leaking sections.

The installation looks clean Jake! Really appreciate the before and after photos as well. Feeback like this really helps the next person looking to tackle this themselves.

The double waste valve assembly looked pretty well-made. However, I had to return it as the ends didn't match my motorhome. I chatted with Audrey through email and she was very helpful.
I tried to contact e-Trailer shortly after I ordered it, to cancel. Their customer Service process is crap. It took 3 business days for them to respond. By then the order had shipped. Bottom line, I had to pay the return shipping. I'll just go back to [online vendor]. Free returns.

Good product, quick delivery.
by:
The product arrived on time and was what I ordered
by:
Product works perfectly and is exactly as described. Seals are tight and had no issues with leaking or difficulty with getting the part into place. I would highly recommend. Had a blowout destroy the previous valve setup and etrailer's customer support was very helpful in finding us a part that would go right in. We were able to get back to rolling thanks to their help.

The item seems to be well made and the design is perfect. I used to have to reach way back to drain grey water, not any more. I would definitely recommend this product!

I held new piece up to old, leaky piece and it looks as if it should bolt right into place. I am doing some work on pickup which won't be back together until next week so wont's be able to pull camper trailer into shop and out of snow till then.

Hi Henry, we hope you're staying warm with all this snowfall! Whenever you get the chance to install, please let us know what you think!

Excellent product, perfect fit, functions better than original
by:
Arrived in a timely manner and was a breeze to install. Since the install time, it works as it should.
by:
These waste valves are exactly as described. Etrailer.com sent the order quickly and it arrived 3 days from when I ordered. The order was complete no missing parts. I have used Etrailer.com before and I will continue to use them in the future. They answer their emails and the phone promptly. They are helpful and caring and they even phone you if they have questions regarding your order before they send it to you. Wow!
by:
My experience was excellent. The online purchase was quick and smooth and I was kept informed during the whole shipping and delivery process. Based on this experience I will not hesitate to recommend etrailer to my friends!

On time and what I ordered. Good service again.

Exact replacement. Good fit works well

Great product! Fast shipping. Very easy installation. Took about 10-15 to install.
by:
Customer service, Lori, was very helpful on the phone. She explained that like so many other businesses these days, they were short staffed- so even though the product was in the warehouse, it was schedules to take 9 days to pull the product, then whatever time it took USPS for standard land delivery. ( at which point I would have missed my camping reservation). So I paid the expedited shipping fee, which also sped up pulling it from the warehouse, and I got my product in 3 days as promised. Thank you.
by:
I received it quickly so I can get this changed out and our RV back in service. The one that is one is replacing had a crack and leaked.
by:
I built a fully equipped toy hauler from a bare shell cargo trailer. This valve works perfectly every time. It was easy to install.
by:
I bought these parts to replace a poorly done replacement on my 2015 Thor Axis. Don't know why the valve set was replaced by the previous owner, but I intend to do a much better job.
by:
As always, service was great, shipment was prompt, and product was exactly what I needed! I love you guys--you are my first go-to when searching for a part for my travel trailer.
by:
Excellent product!, had a little trouble on the install due to location being inside a compartment on my Fleetwood Discovery, but valves work great!
by:
Great price. Costs less than the 2 valves as CW. Fits like a charm and relatively easy to install.

  • Dimensions Of Valterra Double Rotating Waste Valve # T80
    I went to our warehouse and took some measurements of the Valterra Double Rotating Waste Valve, part # T80 for you. I have attached a photo of the valve that has the dimensions you asked about. The distance from the end of the 1-1/2 inch inlet pipe to the end of the 3-inch inlet pipe is 10-7/8 inches. The distance from the outside to outside of the square face plates is 8-1/2 inches and inside to inside between the plates is 5-3/4 inches.

  • Replacement Double RV Waste Valve For a 2015 Nucamp 320s Camper
    Unfortunately Chris, I have no way to see which parts are installed on your 2015 Nucamp 320s. These double RV waste valves only have a few different designs so you will want to try and match yours with one from the list below. # T38 # T18A # TR38A # T80 # 34466NDHR19AAA # TR38B # 34466ND14AAR # T18C # T80A

  • Can Pipes on Valterra EZ Valve Double Electric Waste Valves Be Rotated
    Hey Joe, thanks for reaching out! The waste valves on the Valterra EZ Valve Double Electric Waste Valves # E84-8 are the parts that rotate. If you check out the linked photo you'll see that the Y section of this kit is in a fixed position and can't be rotated. When I took a closer look at your photo it looks like you need a 3" and a 1.5" connection so I believe the Double RV Waste Valves # T80 would be a better fit for your setup. This has hubs for both ends so you'll need to verify those...

  • Replacement Seals for Valterra Double RV Waste Valve Kit T80
    Hey Phil, thanks for reaching out! For a 3-year-old Double RV Waste Valve Kit # T80 you need the -9 versions which are parts # T1003-9VP and # T1001-9VP. You would use the -7P seals if you had an older system. How often have you used the valves?

  • Direct Replacement For A Bristol Double Hub V93B15
    Product # 34466ND13AAR is a hub, a hub or a socket is the common female connection to PVC fittings. While # 34466ND13BAR is a spigot, which is the end connection to a fitting that has to be assembled into another fitting; the spigot fitting has the same outside diameter as pipe. The spigot fitting can be inserted into a hub or socket. The Double RV Waste Valves # T80 is a direct bolt on for your Bristol Double Hub V93B15.

  • What is the Difference Between Valterra Double RV Waste Valves # T80, # T80C, and # T80A
    The differences between the Valterra # T80, # T80C, and # T80A simply has to do with the types of connections that they have. They vary between Hub (female) and Spigot (male) ends to suit your needs. The ends that change are on the side. The top of each part number has a bayonet cap that fits over a 3" lug fitting for your sewer hose. Part # T80 has a 3" Hub (female) and a 1-1/2" Hub (male) Part # T80C has a 3" Hub (female) and a 1-1/2" Spigot (male) Part # T80A has a 3" Spigot (male)...

  • Replacement for Bristol Dual RV Waste Valves V93B15
    Yes, the Double RV Waste Valves part # T80 is exactly what you need to replace the Bristol RV Waste Valves V93B15 that you have now. If you want to reuse your existing spigot flange then they will match up to those on the above as the four bolt flange has the same pattern. This will be a direct bolt-on swap for your trailer.

  • Replacement 1-1/2 Inch Hub and Valve for Valterra T80 Double RV Waste Valve Elbow
    The Double RV Waste Valves - Elbow - Rotating - 3" and 1.5" Hubs to 3" Lug # T80 will use the Valterra RV Sewer Spigot with Flange - 1-1/2" # T1005-1 to match the original hub. This secures to your pipe with solvent # A05-0303. The Valterra RV Sewer hub # T1006-1 will also fit but is designed to fit differently than the T80 original connection so it can be a replacement part as well. I've attached a video to help with the dimensions and a couple photos to further assist with dimensions...

  • Can the Valterra Double RV Waste Valves # T80 Be Rotated to Face Down
    Yes, you can undo the bolts on both sides of the closed valves of the Double RV Waste Valves # T80 and rotate it to face more down towards the hole. I am not sure how closely aligned that would make it because you'd have to rotate it to the next hole, not just exactly where you need it. You can see in the product photos that the # T80 valve typically has the handles coming straight out by the terminal outlet (like you pointed out), meaning whoever installed that valve has already rotated...

  • Can I Use PVC Cement with Valterra Waste Valves
    The Double RV Waste Valve part # T80 is more than likely correct for your 2010 Casita Spirit Deluxe. In order to be sure you will just want to take a quick measurement of the black and grey water lines. The black water line should be 3" diameter and the grey water line should be 1-1/2"diameter as this is standard for RV's but a quick check would confirm this. The PVC cement you have cannot be used with the Double RV Waste Valve as it is made of ABS, not PVC. The Valterra ABS Solvent Cement...

  • Replacement Waste Valves Needed for a 2000 Fleetwood Discovery Motorhome
    It actually looks like you have the Valterra Double RV Waste Valves # T80. This comes with both of the waste valves already installed and they can be rotated 360 degrees on the elbows for ease of installation. We do have replacement waste valves but to know exactly what you need you would have to take your current system apart. If it all comes off as one unit then you can install the # T80. If it comes apart differently please let me know and I can help you find the correct replacement...

  • Replacement Double RV Waste Valves Recommendation for RV
    Thanks for the picture. From that I can point you towards the correct valve setup to replace what's in it as part # T80A. But for the rest of the piping we won't be able to help you as we do not carry it. There are a few different variations of the valve though. Part # T80 has a 3" Hub (female) and a 1-1/2" Hub (male) Part # T80C has a 3" Hub (female) and a 1-1/2" Spigot (male) Part # T80A has a 3" Spigot (male) and a 1-1/2" Hub (female)

  • What is Difference Between Valterra RV Waste Valves T80 and T81
    The difference is the connection the two valves make after the valves come together. The part # T81 uses a spigot connection for a permanent install and the # T80 uses a bayonet style fitting which allows for easier connection and disconnection.

The standard size is 1-1/2" for the grey water tanks and 3" for the black water tanks. If this is what you have then you will want to use the Double RV Waste Valves part # T80.

  • Recommended Double Waste Valve For A 2005 Roadtrek 190 Popular Motorhome
    To determine the correct replacement for your 2005 Roadtrek 190 Popular you'll want to just match how the pipes run since there a few different designs. The # T80 line has both the 3" and 1-1/2" lines running in horizontally to the main dump tube opening with different spigot and hub fittings on the ends for the connection. As long as each of these lines up correctly with how your pipes run you can use any of them and just un bolt the flanges on it and the old one and just swap it out....

  • Is the Double RV Waste Valves # T80 a Replacement For Airstream Valve Part #601482
    The 601482 number you provided is an Airstream part number. But I was able to locate some information with that number and it looks like it is in fact the Double RV Waste Valves # T80. After comparing the Double RV Waste Valves # T80 to the valve I located using the 601482 number, it looks like Airstream just changed the part number to 601482 and the # T80 is the same waste valve you currently have.

  • Recommended Replacement For A LaSalle Bristol V93B1 RV Sewer Fitting
    Thank you for the pictures of your LaSalle Bristol V93B1, it made it a lot easier to find the correct replacement to get your RV's sewer system back in working order. The V93B1 appears to just be the actual drain pipe with the gray dumping into the black line and doesn't include any valves. You'll need the Valterra RV Sewer Heel Inlet # T1030. This is going to have the same 2" hub fitting and 3" rotating flange as your V93B1 so you can easily swap it out. You'll need some ABS Cement #...

  • Can A Single Gate Valve Be Replaced Or Does The Whole Assembly Have To Be Replaced
    Each gate valve is held in place by four bolts that you can just unscrew and then swap the gate valve out with a new one like Valterra's Bladex # T1003VP and bolt back in place. If your gray gate valve ever needs to be replaced you can use part # T1001VPM. This method means no cutting and gluing in extra fittings for just a simple valve replacement. I've attached a video where I show you exactly how to do this.

  • Difference Between 3 inch Hub and 3 inch Spigot for Doulbe RV Waste Valve Setups
    Basically the easiest way to describe it is that hubs fit over spigots. So the Double RV Waste Valves - Elbow - Rotating - 3 and 1.5 Hubs to 3 Lug Item # T80 that you referenced has a 3 inch fitting that is 3 inches in internal diameter designed for fitting over a 3 inch outer diameter (spigot) fitting. These kits do not come apart so you'd have to replace the entire thing.

  • Replacement Valves for the Double RV Waste Valves Part # T80
