Never had to fix somthing like this. etrailer made it stress free! Great price, the part showed up a day early and the install left me feeling like I hadn't done much at all! Thank you etrailer!

Use it everyday, no leaks yet!

Thanks for the follow up. The shipping was great and the parts got here on time. I did the installation today. Attached are before and after pics The others are after I finished - no more cable actuated valves - YAY! Feel free to post them!

- T84

As nasty as playing with the poo pipes this was great to install. I only wish I would have noted to myself that there are grey and black handles to determine what tank you're draining. This version fits perfectly as a female fitting to 3" abs pipe.

- T84

My grey and black sewer lines were damaged after being forced onto the interstate shoulder by a semi. I tried to replace the ABS pipes from local HW stores to no avail.A After five minutes on the phone to etrailer I not only found all of the components but they shipped them out right away. I am very happy with both the products and the customer service.

A year later and still works exactly like day one! etrailer will always be my go to for trailer part needs :

Haven’t installed it yet, but it definitely feels well built and solid.

- T84

Easy install. Nice to be able to turn the outlet a bit so it can be pointed down for better drainage. Different colored handles is a nice feature. The ease of being able to drain both tanks next to each other.

  • Recommended RV Waste Valve For 3-Inch Line
    The double valve you need to install on the 3-inch waste pipe in the photo is part # T84. This is the female valve designed to fit over a 3-inch pipe. To cap the 3-inch line you would need part # T50B. This is a waste valve that comes with a 3-inch bayonet cap. If you are wanting to cap the 1-1/2 inch waste line you can use part # T1001C. This has the hub that fits over the 1-1/2 inch waste line and a threaded cap included.

  • Can I Replace individual Drail Valves Or Must I Replace The Entire Valterra T84 Unit?
    On your 2010 Winnebago Vista 30W, if it has the Valterra Double Rotating Waste Valve - 3" Hub x 3" Hub x 3" Bayonet Cap # T84, # T85 or # T85B, then you can replace the individual valves. For the valves, you will want the Valterra RV Waste Valve - 3" Hub x 3" Hub # T40B and you will use the already existing tube connections and utilize the inner assembly.

  • How to Improve Access to Black and Gray Water Drain Valve
    Thank you for the photo of the black/grey water drain valve on your Forest River Salem 31QBTS travel trailer. I see what you mean about this being well under the trailer and not located for convenient access. Sometimes the presence of slide out mechanisms or other RV features can limit the placement options for the waste valve. RV makers might choose to keep the drain well under the trailer to avoid a nasty problem were it to leak while you're driving. (Consider what would happen if...

  • Replacement Waste Valve Assembly for a 2007 Keystone Passport Ultralite
    I would love to help but I do not have any information that tells me what size drain pipes are on your 2007 Keystone Passport Ultralite so you will need to measure this for yourself. 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. The grey water tank could also be a 3" diameter and if that is the case then you will want to use the Double RV Waste Valves part #...

  • Availability of Replacement Double Valve for 2010 Pleasure Way Plateau
    Sounds like you are looking for a double valve similar to the part # T84 from Valterra. That said I'd need more info to know for sure which of these is the correct fit since they are all universal. Pictures would help as well. I attached a link to a page that has all of the double valves we carry as well. In case the terms "hub" and "spigot" are confusing the difference is that hubs fit over spigots.

  • What is the Difference Between Double RV Waste Valves # T84 and # T84B
    The outlet tubes on Double RV Waste Valves # T84 are larger than those on Double RV Waste Valves # T84B. On the T84 the 3" Hubs slide OVER your RV's black-water lines. On the T84B the 3" Spigots slide INTO your RV's black-water lines. I have included links to videos on each.
