Video Transcript for Valterra RV Sewer - Waste Valves - T50 Review

Today we're going to be taking a look at the Valterra RV waste valve. This unit simply adds or replaces a waste valve on your RV's waste system. It's going to be made from a strong and durable black plastic construction. It does come with the end cap right here for the drain outlet. The cap is going to be tethered to the unit so you don't have to worry about accidentally losing that or misplacing it. The connection point right here for your drain hose, this is going to accept your standard three inch diameter drain hose with a bayonet style fitting. That's got four attachment prongs on there.

Then you're going to have the easily accessible handle up here that's a t-grip handle. That's going to open and close the gate. The other side that connects to your RV's plumbing system. This is going to accept three inch standard plumbing pipe, so what we can do is simply take an internal measurement of that. As we do, you'll see that that is going to give us a measurement internally of about three and a half inches.

That's the diameter there, inside edge to inside edge, so your plumbing pipe on your RV, that's going to have an internal diameter of three inches. That's going to have quarter inch wall tubing on it. When you combine that three inch inner diameter with a quarter inch on each side of the tubing, that's where we get the three and a half inch diameter from, which will fit perfectly inside of the connection point here on this waste valve. Overall, it's a nice structural design. The hardware's included. The unit's already pre-assembled.

The t-handle's going to make opening and closing the gate quick and easy. The unit's already assembled and it has the appropriate seals internally to offer a leak-proof performance. The last thing I want to mention is I just want to go over some overall measurements with you. What we can do is I'm just going to take and overall length measurement of the unit with it closed and then with the handle fully extended. When we do that from edge to edge, we're looking at a measurement of about nine and a half inches. When we extend that out, that's going to increase it to around 13 inches.

That's going to do it for today's look at the Valterra RV waste valve.

Great…thanks for a good product



by:

I no longer have to reach under my motorhome to connect the drain hose thanks to the added waste valve. Works perfectly.

Winton

One of my best purchases. Really makes drain process so much easier and cleaner.



by:

Last November I purchased a drain valve from etailer. I recently got around to installing it on my 2018 Montana High Country fifth wheel camper. The valve shut offs are operated by (throttle) cable. These valves do not always close completely. I chose to install the valve at the outlet just in case the cable valves don't completely close. Attached is a before and after picture.
Thank you etrailer.



by:

It was exactly what I ordered,One on my travel trailer,hanger broke,it kind of disintegrated,before I noticed it,while dragging on the street.This looks easy to replace and will be good to go on my next camping trip.
I have order things before from ETrailer and am always completely satisfied.



by:

My experience with Valterra valves is that they're very reliable and of good quality. This valve fit perfectly for my application (on a 3in ABS sewer pipe) I was able to install in minutes. Used my old cap as it has a hose bib.
Very satisfied with price, quality and fitment.



by:

Fast service. Great product



by:

High quality, durable, made to last



by:

Product arrived as expected. I haven’t installed the product but have exercised the valve found it to be lubed properly and function smoothly and it confirms while my current valve is operable its not operating properly so I’m glad I’ll now be able to replace it with a quality product and have peace of mind that I’m not polluting the highways with you know what. It combines and replaces two separate parts for my specific RV so it’s all around a win win



by:

Works as intended. Slide is easy to move and seals to prevent water bypassing the gate.



by:

The waste valve is really a must have. If you have ever opened the cap on your sewer drain only to discover that one of your valves was not shut properly, you will understand why. It is easy to install and smooth to operate.



by:

I won't have any surprises next time I remove the cap to attach the sewer hose.



by:

Works very well. As always, very fast shipping, item as promised.



by:

I would swear I bought the slip on version but in my case this version that was shipped worked perfect. 2020 Jayco has two grey and one black exiting to this 3" RV drain. Consistently I would get at least one gallon of grey sewage when opening the cover. Could be a leaking valve (hidden away under the bellows skirting or it could be residual in the pipes. In either case I hacksaw cut out the existing bayonet hub then cemented this in (just like your PVC sprinkler pipes) it's place at the end of the run. So I now have 3 stock valves and one new 3" value exactly the same distance under the trailer as was the stock cover and bayonet hub. You might call it my emergency valve. Easy access and easy maintenance...the way it should be! I did not buy the ridiculous $5,000+ warranty and dealer wants $180 per hour not including the repair, plus the tech never called my back. Typical customer service in the RV world. Works if you have enough PVC exposed to make the cut. Sorry no photos.



by:

Great quality and item was as advertise d.



by:

Was a bit more difficult to install than anticipated. Matting up to the old plumbing was interesting. In the end was able to get everything working properly. Has seen limited use since the repair. Did do a cursory look at it the other day and all worked as it was supposed to. Happy with the results.



by:

Had a cable system for black and gray disposal. Always hard to open. Replaced with traditional valves. Worked perfectly.

Works good



by:

Products are delivered as promised.



by:

Had one of my valves that leaked and when taking cap off to hook up hose, out came a mess on ground. This installed on end of dump pipe ended that problem.



by:

Excellent quality, packaged very well. Arrived sooner than expected! Great online service for parts. Parts will be used to separate black water from grey water, black water to septic, grey water to tank for other uses. Thanks again,



by:

Great product to prevent surprises when it's time to empty the black and grey tanks. It's also a backup in case one of the drain valves gets stuck open.



by:

I ordered a Valterra 3" RV waste valve. This valve was shipped and received very fast. I haven't had a chance to install it yet. I'm sure it will do what I need it to do. It will be used on a portable dump tank.
Very good service from etrailer and I will order from them again.



by:

Excellent service!



by:

Easy to install, works great! Going to buy another to re-plumb my main sewer line.

William M.

7/8/2021

After one year the valve is still working great. I’ve now installed a second valve on my rear tank and can’t say enough good things about the quality and durability of the valve. Highy recommended.



by:

Everything is fine with the part....Wish you would have sent me the tracking # like I requested after your e-mail stated it was forthcoming. We live 18 miles one way from the Post Office and don't get Mail delivered to our Address, too many wasted trips.



by:

e-trailer always gives me fast service with fair pricing. I have 2 boats, 1 RV, and a motorcycle trailer all complimented with upgrades from e-trailer.

  • How Long is the Valterra Bladex Waste Valve for RV Black Water Part T50 From Each Fitting

  • How To Remove An Old Waste Valve Flange Fitting To Install A New Waste Valve
    Hi Nicole, The only way to remove a fitting with ABS cement used on it would be to cut it off from the pipe. If there's nothing wrong with the flange then I recommend just removing the gasket that's still sticking out from it and removing the flange fitting on the new waste valve # T50 and then bolting it to the old flange fitting. Just make sure you use the new gasket from the # T50 when connecting to the old flange. I've attached a video below where I did this on a double waste valve...

    The Valterra Waste Valve for RV Black Water Tank , # T58 has a bayonet style connection. It will lock in to place from the four bayonet connections on one end and 3" Lugs on the other. Please see the attached image. If you are looking for something that accepts standard 3" plumbing pipe, the Valterra Bladex Waste Valve for RV Black Water Tank - 3" Hub to 3" Lug, # T50 is available. This requires an ABS solvent for installation. Please note the attached product review video.

  • Why Are Openings on Valterra Waste Valve for RV Black Water Tank 3" FPT to 3" Lug Different Sizes
    The end of the Valterra Waste Valve for RV Black Water Tank # T50B that has the lugs has a 3" diameter but the other side with the threads is actually designed to fit over a 3" diameter threaded sewage pipe which is why it measures 3-1/4". As long as you have standard pipe sizes on your RV and the outlet as a threaded end this waste valve will work for you!

  • Difference Between Valterra Bladex Waste Valves T50 and T50A
    So the difference is purely in how the two connect to your sewer pipe, which will also tell you which one you need; one will slide into the pipe (the spigot) while the other will slide onto the pipe (the hub): - Slide Into Pipe: Valterra Waste Valve for RV Black Water Tank - 3" Spigot to 3" Lug # T50A - Slide Onto Pipe: Valterra Bladex Waste Valve for RV Black Water Tank - 3" Hub to 3" Lug # T50 To secure the valves to your pipe you would just need the Valterra ABS Solvent Cement # A05-0303.

  • Will the Valterra Extension Rod Kit # T1046-12VP Fit a Plymouth Waste Valve
    I am not sure if the Extension Rod Kit # T1046-12VP will be compatible with your current system but I did go out to the warehouse and measured the outside and inside diameter of the rod with a digital caliper and found those to be 0.30" and 0.20" respectively. If your current rod has these dimensions then it is possible it will work.

  • Troubleshooting An RV Waste Valve Gate That Is Not Opening When The Actuator Is Pulled
    It is completely within the realm of possibilities that the actuator has become disconnected from the gate internally causing the valve to not open. The Valterra Waste Valve Body for RV Black Water Tank w/ Coupler, Seals, and Hardware - 3" Diameter # T1003PBC you were looking at will mount with four bolts allowing you to easy swap out the old valve and install this new one. An example of this valve attaching to other fittings using four bolts would be the # T50A. I recommend just replacing...

  • Are RV Sewer Drain Hoses Universal
    There are generally two wastewater tanks on an RV. The grey water tank which contains waste from the sinks and the black water tank which contains waste from the toilet. The grey water tank generally uses a 1-1/2" diameter tubing whereas the black water tank generally uses a 3" diameter tubing. If you measure the diameter of the waste valve that should give you a good idea of what size you need but most do follow the 3" diameter for black and 1-1/2" diameter for grey standard. In addition...

  • Adapter Recommendation for Connecting to Bayonet Fittings of Valterra Waste Valve T50
    Sounds like you're possibly in need of an adapter to connect to the bayonet fittings of the # T50. The part # CAM39471 is an adapter that can swivel and has 4 different styles of fittings it can connect to. I attached a review video for this adapter for you to check out as well. Since you didn't tell me what kind of fitting you have I can't specifically say if this comes with something compatible. Or maybe you are looking for a 3 inch diameter PVC pipe to go from the waste tank to the...

  • 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.

  • What Adhesive Is Used For Valterra RV Waste Valves
    The waste valve you came from, part # T58 is not a valve that uses glue because it is designed to attach to the RV side and the waste tube with the bayonet adapters on each side of the valve. We do have waste valves that do require gluing. I have attached a link to the waste valves we offer. You can use the filter on the page to find the correct size you need. We do offer part # T50. This has a cap with a bayonet fitting that you attach your drain hose to. The other side of the valve is...

  • Adding a Blade Valve to the end of my Tanks Dump Plumbing
    While there isn't an adapter to go directly between the Valterra Waste Valve for RV Black Water Tank part # T50A can be added on in place of your current 3" lug cap in place now. Simply cut it off and attach this one using the LaSalle Bristol ABS Solvent Cement part # 3447530889. This will give you the valve in place to keep the stuff off of your hands.

    I do have an option for you, however the exact valve body that is included with the Valterra Waste Valve w/ Flexible Cable # TC372 you mentioned is not available as a separate part from the manufacturer. What you can use instead is the Valterra Waste Valve Body # T1003PBC. This is a very similar valve body that will work the same as what is included with the kit you mentioned. The body features a 3 inch diameter passage to allow wastewater to travel when it's open and the body, seals,...

    Yes, the Valterra RV 3 inch Waste Valves, like part # T50, are designed to fit standard waste fittings. The part that I referenced is just the regular waste valve. If you are looking at a specific design, you can find a variety of designs on the linked product search page.

    There's quite a few different styles of waste valves that could be on your 2007 Sunnybrook Titan 30FKS, so you'll need to take a picture of what you have and send it to me. The most common are a wye connection like the # TR38A which ties the black and gray water into the same outlet, or the single black water valve # T50A which just goes in-line of your 3" black water waste pipe. Let me know what you have and I'd be happy to confirm the correct replacement.
