Replaces the valve for your RV's black-water tank. 3" Diameter passage allows wastewater to travel freely when valve is open. Valve body, seals, nuts, and bolts included.
Features:
To install, remove the broken waste valve and seals from your black-water tank. Then place the included seals on the flange fittings and position the new valve body. Tighten the provided hardware to complete installation.
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we're going to be taking a look at the Valterra Bladex Waste Valve. This is a three inch valve. It's going to allow you to replace, repair, or upgrade to a new dependable valve. It's got a metal handle right here on top. Very strong, durable design. You shouldn't have to worry about that ever breaking.
That's going to sit on top of a stainless steel shaft that's going to be strong and durable, as well as highly resistant to rust and corrosion. Now, these valves are interchangeable with most other brands. It's going to include the valve, the seals, the nuts and bolts for your full installation. The seals are made from a santoprene construction that's designed to resist chemicals and corrosion. Now, when you're ready to install the unit you'll need to remove your old valve and seals. Place the new seals over the lip of the existing flanged fittings. Insert the new valve, being careful not to dislodge the seals.
Then, tighten everything down for your full installation with the included hardware. A few measurements to go over with you real quick. I do want to mention just how easy of an operation it offers. Really nice design. Allows you to easily open and close the unit. You've got the T-grip handle right here and it just operates really nice and smooth.
Now, the overall length of the unit with it in a closed position is going to be about nine and a half inches. With it open we're looking at about twelve and three quarters of a inch. The width is going to measure about four and three eighths of an inch. Then, it's got four mount holes that's going to be a square pattern, so the distance that we have between each hole, measuring on center, is going to be about three and three quarters of an inch. That's going to be the same separation between each hole. That's going to do it for today's look at the Valterra Bladex Waste Valve..

Works great so far quality is why I went this route because thats what came with my high end motor coach. Thank you.
I was highly impressed with my first experience with etrailer and Karen, the assistant who helped me with my order. It was exactly as advertised and at a very fair price. I used economy shipping and received my order in three days.
I will definitely go right to etrailer the next time I need RV parts.

Perfect fit.
Valterra Bladex Waste Valve Body for rv waste tanks, fit and function was perfect. I purchased the valves with the new seals and bolts. Changed both in about 10 minutes. So if you have a gray water and black water tank, go ahead and replace them both. Your there one time to take care of any problems.
This item was out of stock for several weeks but etrailer stayed in touch with me and keep me informed of the status of the order on a regular basis. The item arrived last week and now I am ready for my next camping trip. I have ordered from etrailer in the past. Thier customer service and products are second to none.
There is nothing glamorous about buying 3" DWV fittings. But, etrailer made it easy with their great website and helpful videos. Was able to order all the fittings I needed to install a Sani-Con on my fifth wheel.
Easy to install. I would recommend to coat seals with petroleum jelly to hold in place while installing. Make sure black water tank is well drained and cleaned out before beginning install. Otherwise could be smelly business.
The product arrived on time installation took less than 30 minutes repaired my leaking problem very satisfied I will definitely be shopping with you guys in the future and I'm going to tell everybody I know that RVs

Holding up well still makes a great seal
The items were shipped right away and they were exactly what I ordered. I have not installed them yet, but I do not anticipate any problems as it looks like they have everything that I will need included.
Works good
Very fast delivery. Product fit perfectly . Good quality.
Good product
Original replacement part, fit as expected. Very quick shipping and delivery.
Good fit….works great!
Great price and products. Could have been shipped quicker.
Converting airstream thetford valve to vaulters. The combination I chose dropped the drain 2” below the belly. I’ll have to install a grey tank to tuck everything up in my 73 Sovereign 31’ center bath rv.
Only came with one gasket. I had to use an old one on the down stream side.
SMOOTH OPERATION
Thanks for the email
I don't have much to say about the product. It is static in the open position 90% of the time.
I do appreciate how you at etrailer have kept me informed and asked questions, insuring that I am satisfied.
You may be able to tell from the attached photos, we are using these as gate valve for a fume exhaust system.
These are old photos. We have moved to a new facility, and the hoses are upgraded.
Easy peasy to replace on my camper.
I installed this valve as a replacement, a year ago, and have had no problems with it. this is well made.
item as described and delivered as prom ised.

It works and I’m glad etrailer had it in stock. I accidentally bought the wrong one the first time, no fault of etrailer, but a little disappointed it cost $[XX] to ship the first one back.
I just like to thank Greg. I believe that was his name for checking on the delivery time of my item that I ordered from E trailer he assured me that the peace would be here today and low and behold I got it. Thank you very much. Oh, and if I could just say one thing to E trailer, you should offer a discount for military personnel I think you would get a lot more traffic. I know I would shop there more thank you very much.
Working with the ETrailer staff was very easy and they provided great customer service. The 3" Valterra Bladex Waste Value is well built and was easy to install.

The 3 Valterra Bladex Waste Value has been working well without any issues since I installed it a year ago
Perfect and easy to install…saved $1k in installation by local RV (highway robbers). Thanks e-trailer!
