Amazing service. Fast shipping
Perfect replacement part for my truck c amper.
Looks well made and seems to operate smoothly. However, it will be awhile before I get to install it and use it so I can't comment any further at this time.
Haven't put it on yet but looks good. Fast delivery. Good price I guess. This was easy. I like easy
Fast shipping and great products!
Exact replacement. Didn’t have to replace any of the glued pipe
5 stars for sure
I am Amazed, Must be my lucky day, your plastic assembly made it

or any other protection, arriving in excellent condition ! Thanks!

Boy am I Lucky, That Valve Still Works !!
SOLUTION! This gets the valve well in the OPEN, making my life easier fer real. FYI dry fit everything first use a sharpie to mark the position glue and reassemble will make you a Happy Camper tooo
Was an exact replacement for my broken valve. Easy (but messy) to swap out.
Worked well. Exact replacement for. Took approx. 20 mins to remove and replace in my parking space. GreT to get the new valves as part of the package.
Very fast service! George J decided to expedite my order and it arrived VERY FAST making it possible to continue my trailer modification much sooner that I expected! Looks like high quality product and I'm sure it will last a long time. THANK YOU! THANK YOU!
Hey, I have a hard sided pop up that had a separate black and grey outlet. Trouble was there’s only one inlet for was and it was a struggle to empty the grey line. This tee fixed the problem.
exactly what I needed to repair my leaking tank valve. This valve so far has not leaked and seems to be a quality part.
Haven’t install it yet but looks pretty straightforward.

Excellent product provided a option from tearing out my enclosed valves on my older trailer.

After damaging our original, this was an exact replacement and easy enough to install using the appropriate glues. The outlet cap is much tighter that the original and really requires a universal oil filter wrench to remove and install.
This valve was perfect for the reconfigure of my gray and black tank. With both valves being able to rotate for installation, I was able to get the position I needed. Thanks for the video showing it's features, the ease of ordering and the on time delivering!
Cannot believe how easy this was - arrived in two days as promised and exactly what we needed. Unfortunately, when moving the trailer to install the fitting, we caught the black water tank on a covered rock. I know - we are very tough on exposed plumbing. Doesn't look like etrailer has those kinds of parts - too bad.
Fit perfect!!

Dont know. Sold TT before using it......fit when I put it on though.
Great replacement valve. Fit my kn sportsman classic perfectly.
exactly as advertised. both inlets rotate without any modification at all. The construction is solid and the dimensions are accurate. highly adjustable, heating the black tank outlet a bit with a heat gun made this unit slide on like butter. I used two CV joint boot Oetiker clamps of the appropriate size in the black tank inlet, instead of c-clamps.
The valve worked perfect
A hard to find part. Always rely on Etrailer for hard to find parts

Flawlessly. Ended up being the right choice.
A low driveway wipe out my dump valve. This was a exact copy replacement. I was able to replace the valve body and gate valves without cutting abs pipe. The original slip fittings matched perfectly. I'm very happy with this product.
Part arrived quickly, replacement well as part was almost an exact replica of the frost damaged one.
The rotating double waste valve was a prefect fit for my RV. It is a quality product. The valve was shipped promptly and exactly as described. I have consistently received prompt and reliable service from etrailer.
