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.

Valterra Bladex Waste Valve for RV Black Water Tank - 3" Hub to 3" Lug - T50

Average Customer Rating:  4.9 out of 5 stars   (98 Customer Reviews)

Replaces the valve for your RV's black-water tank. 3" Diameter passage allows wastewater to travel freely when valve is open. 3" Hub slides onto sewer pipe. Bayonet cap fits over the 3" lug fitting that connects to your sewer hose.

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:

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:

received T 50 valve one day earlier




by:

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




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:

Solid construction. Very smooth valve operation.




by:

showed up early and install was easy




by:

Builders who don't make the last sewer connection like this one are negligent. This is only way to prevent drips. Easily installed.




by:

Great product exactly what i needed




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:

Don’t know where it shows it was delivered but I never received it the last report was it was to be delivered Jan 31 2022,but never received it I was in need of it because of leaving on a trip, I had to buy one to be delivered next day


Comments
I will have our customer service team reach out to you.
-- Etrailer Expert Jenny N - 02/19/2022


by:

Shipping was prompt. Received in perfect condition. Fit perfectly. Operates perfectly. All I could ask for.




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:

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


Comments
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.

Arrived quickly..!




by:

Good stuff it fit great




by:

Products are delivered as promised.




by:

Great product and easy to install. Solves the problem of leaky valves leaving a surprise when opening the dump cover to hook up hose.




by:

out standing,,love the detail of tracki ng.




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:

It’s nice to have you to depend on with your quick service.
Thank You




by:

Installation was quick and easy. Fits like a glove. Love it




by:

Fitment is excellent and works as it should! Nice tight close. I bought this to add at the end of my drain as the one inside the body wasn’t quite closing off properly leaving slight drainage.




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 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,

    The Valterra Bladex Waste Valve for RV Black Water Tank - 3" Hub to 3" Lug Item # T50 can fit a 3.5" outside diameter pipe to connect to your 55gal barrel or if you cut a hole in the barrel and use some waterproof caulk you could attach it directly to the barrel.

  • T-58 Waste Valve With Bayonet Connection
    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.

    The Valterra RV Waste Valve, part # T50A, consists of both the 3-inch valve spigot and the 3-inch bayonet outer cap. You can see this item in the linked 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...

  • 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...

  • 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...

  • 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.

  • Recommended Black Tank Valve Replacement on 2018 Jayco Camper
    I believe that I understand what you are saying and recommend you use the Valterra Bladex Waste Valve for RV Black Water Tank - 3" Hub to 3" Lug # T50 instead of the threaded # T50C. You would simply use the Valterra ABS Solvent Cement - 1/4 Pint # A05-0303 to bond the two pieces.

  • 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...

  • Availability of Valterra Waste Valve Body without Cable
    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,...

  • 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.

    There isn't a guide showing the exact black tank waste valve used on your 2016 Airstream so I have a few examples for valves you can use. If you are replacing just the valve between two flanges then the Valterra Bladex Waste Valve Body for RV Black Water Tank # T1003VP is what you'll want.

  • Replacement 3 inch Waste Valve to Replace Bristol Waste Valve
    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. You will want to make sure to use Solvent Cement, like part # A05-0303, for a complete and secure installation.

  • Replacement RV Black Water Waste Valve for 3-Inch Sewer Pipe
    It sounds like you're looking a for a new valve assembly for your black water tank. For a black water waste valve for a standard 3-inch diameter twist-on bayonet/lug fitting you can use Valterra part # T58. If your RV instead has a straight sewer pipe you can use the slide-on Valterra valve # T50. This item must be glued on using Valterra ABS cement # A05-0303.

  • Replacement Blackwater Valve for 2003 Montana Fifth Wheel
    Since the valves are plastic welded to the sewer pipe you'll have to cut off what you have and install a new one. So you could use the Valterra Waste Valve for RV Black Water Tank - 3" Spigot to 3" Lug # T50A which you'd use the solvent part # A05-0303 to attach the spigot end to the pipe and then can use the lug cap to go over the valve when not used.

A few of the different styles are a single 3" waste valve like the Valterra Waste Valve for RV Black Water Tank - 3" Spigot to 3" Lug # T50A, or a combined black water and grey water valve like the Double RV Waste Valves - Sewer Wye - Rotating - 3" Spigot and 1-1/2" Hub # TR38A.

  • Recommended Waste Hose Setup For A Flagstaff E-Pro E12RK Travel Trailer
    Based on the photo you sent in it looks like someone glued on a piece that isn't going to allow you to use a standard waste hose. The solution to this issue would be to remove the waste valve and replace it with another that is compatible with a standard waste hose like the Valterra Waste Valve # T50A, which would allow you to use the # D04-0115 waste hose you were looking at. Waste valves fit specific size pipes so you'll need to ensure you're getting the correct size before ordering....
