Video Transcript for Valterra Bladex Waste Valve for RV Black Water Tank Feature 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 in your RV's waste system. It's going to be made from a strong and durable, black plastic construction. This is designed for three inch diameter piping. It's going to feature a male pipe thread on this side and then, we're going to have a female pipe thread on this side. If we take a measurement of the outer diameter right here on the male pipe thread, that's going to give us an outer diameter of about three and a half inches. Here on the female pipe thread, just the threads that are on the inside of the pipe, inner diameter is pretty close to three and one quarter inches.

It's going to feature the easily accessible T-handle. It makes opening and closing the gate quick and easy. It's going to be black in color. The unit is already assembled and has the appropriate seals installed for leak-proof performance. If we take measurement of the overall length going this direction with the handle in the closed position, that's going to give us a measurement of pretty close to nine and a half inches. If we open that up, take another overall length measurement, that's going to give us a measurement of pretty close to 12 and three quarters of an inch. Also, I want to point out that on the male pipe thread inside, we're going to have a little nib right here.

That's an attaching tether 00:01:36 if you want to use like a threaded cap for this side so that's there that we can attach it and you don't have to worry about misplacing or losing the cap if you want to do that. That is sold separately. That's going to do it for today's look at the Valterra RV waste valve.

Needed a secondary valve on my black water line. This valve works great.



by:

Impressed with the quality when inspecting when received. Valve opened and closed smoothly and the seal felt solid.



by:

still waiting for this to show up



by:

I wanted to take a moment to thank Rose. I wrote a review because my product hadn’t come for over a month. I had no confidence that I would get it. However Rose called me and was very apologetic and shipped me out another, which I got within two days. It was good seeing that someone actually reads the reviews and corrects the issue



by:

Fit perfect no leaks



by:

It prevents any surprises. You will need to cut off the twist fitting and use ABS glue for the installation of this model.



by:

We have a unusual application for these valves. We use them to empty the water out of sample drawers that we use to bring up deep sea animals and rock samples etc.. The drawer in the photo holds 50 gallons of sea water. Once the samples are removed, we need to empty the internal water as quickly as possible. These valves when open empty the 50 gal in minutes. The low profile design helps save valuable space. The sample drawers are mounted on robotic submarines capable of diving several thousands of meters deep.

Fort perfectly

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:

Amazing service, their team offers great assistance to fulfill your needs.



by:

I have a Hitchhiker 2 that features a waste valve connected to the tank, which is located in the middle, under the camper, with extended handles that I purchased, enabling me to access the valve from the side of the camper. Once I removed the under belly and replaced the valve they seem to work great



by:

Works perfectly for our motorhome. Great product.



by:

Fast shipping and everything seem to work great.



by:

Fit perfect & was made heavier, better quality, than the one I replaced it with.



by:

I had to replace approximately 24 inches of pipe, elbows, and blade valve. It took me awhile to find out that ABS pipe is measured Inside Diameter, and I didn't want to cut the pipe until I was absolutely sure. Once I was sure, it all went in well. I used a flexible straight connector to put it in place, and that solved many problems. Attached is a photo of my finished assembly.  By the way, that "liquid sealant" sold in stores is Worthless!



by:

I purchased 4 gate valves for a home-made pond filter system (the MK-2 from England). They have worked as advertised. I have had to re-apply some additional rubber caulking due to a tiny leak (not due to the gate valve). Otherwise, no complaint. If I've ever the need, I'll probably look to this gate valve again in future.



by:

The valve arrived as promised in excellent condition. The valve was made of heavy duty material and fit perfectly.
