Video Transcript for Valterra RV Sewer - Waste Valves - T40 Review

Today we're going to take a look at the Valterra RV waste valve. It has the 3-inch hub side and a 3-inch spigot side. This is made of a durable, hard plastic construction. This waste valve will replace a broken or warn out one on your RV's black water tank. It is used to stop or allow the flow from the tank. You notice when you open it, it has a 3-inch diameter passage which will allow waste to travel freely when it's open.

When you do close it, there are seals in there, which will tightly seal off the black water pipes when it's closed. The 3-inch waste valve body, which is this whole section right here, with the handle on it, is a Bladex design. It is used to open or close the tube opening on the waste valve. The valve body itself, you can see when you open it, has a nice metal shaft with the plastic handle. If you notice the plastic handle is color-coated black also to let you know it's for the black water tank. I just want to give you a few internal dimensions here.

On the hub side, the internal dimension is going to be right at 3 1/2 inches, and on the spigot side, internal is going to be right at 3 inches. That should do it for the review on the Valterra RV waste valve, the 3-inch hub side and the 3-inch spigot side.

The OE gate had a long cable that was a problem from day one, I installed the gate near the exit of the system and am happy with the valve I have now it's got a positive close position with no leakage, I didn't remover the cable gate just left it open. I didn't have to use the termination adapter. I'm happy now. Thanks

Great product. Installation went good. Did it on a 7 year old trailer. My suggestion is for anyone that feels a drag starting with their valve and feel it will need replacement, to start by taking your time to remove the bolts carefully and replace them with stainless steel bolts. Once you get past the bolts froze in, valve replacement is a breeze.

This valve saved me from having to crawl up under my trailer and pull the PVC plumbing apart to replace the Thetford valve on the black water tank. The in-line valve would not seal/close completely. That meant when I pulled the cap off my drain to empty the tanks there was 'stuff' there waiting to spill out. I took that cap off and replaced it with this valve and it solved my issue for 6 months until I was ready for service. It stayed in place and did not leak.

First I have to comment on the customer service from Lisa D. She is the best, not 5 stars, but 7! She went to great lengths helping me find a solution to a particular need. I bought this Valterra RV valve to divert water between tanks in a rain water harvest system. It is smaller, lighter and easier to use than ball valves, etc. The product is good quality and very economical. The product is just what I needed, the shipping was fast and the customer service outstanding. I would highly recommend Etrailer.

Bought 3 of these to use as slide gates on the bottom of grain chutes in our barn. They weren’t quite as heavy duty as we hoped but probably fine for the price. All 3 are still working but the handle has broken on one of them.

We were having trouble getting the black water closed because the chain link that opened the drain was just not working. We called around about getting it fixed and after we heard how much it would cost decided to fix it ourselves. We found your product and bought it and my husband fixed the drain pipe yesterday. I'm happy to say it worked great and it was not too hard to install.

Great service on questions about my order. Sale dept contracted me that my order could not be shipped due to the manufacturer was behind in my part number. Sales/service was able to supply me with a similar part number and was able to ship it out right away. Sales /service told me it would be 7 to 10 days before I would receive it. I received it in 3 days. Thank you sales/service for a great job and for being so helpful in getting me my order so quickly. Pete E.

The dump valve arrived today. I have not installed it yet, but it looks like it is built very well. A high quality part, not cheap looking. It should install easy and last longer than the fifth wheel.

  • Replacement Waste Valve for Black Water Tank
    Based on your picture (they did make it through) it does appear that the Valterra waste valve # T40 is the correct part for you if it requires a 3 inch. The other common size is 1-1/2 inch but yours looks larger than that. I have linked a video review of this valve for you.

  • How to Determine Correct Waste Valve for RV Black Water Tank
    Ok so it sounds like what you are wanting to do is just replace your black water tank's waste valve, and I can let you know how to determine the correct one, as there unfortunately isn't a way for us to know the exact valve for your R-Pod. It's pretty simple though, because you just need to know if the valve you are replacing slid over your pipe or into your pipe.

  • Replacement Valterra Waste Valve 601607-11 For Airstream Trailer
    The Valterra Bladex Waste Valve Body for RV Black Water Tank part # T1003VP will replace the valve but the part that you have now has a 3" spigot hub on both sides. This valve would require some modifying to fit into the same place as your old valve because you would have a gap. Therefore I recommend Valterra Bladex Waste Valve for RV Black Water Tank part # T40 which is a 3" hub to 3" hub spigot like you need. That is the reason the Valterra Bladex Valve part # T1003VP is listed differently....
