Ratings & Reviews
Product was received in good condition. I was contacted by etrailer with notice that my shipment would be delayed. I appreciated the heads up so I could plan accordingly. However the product was received about the time I originally expected.
The product also worked for me. I was a little concerned that I would have to alter plumbing on my trailer, but fortunately I did not. Many thanks for the service and for getting me what I needed.
Bought this double valve to replace the one damaged on my RV. Received a quality replacement that fit perfectly. The replacement part was well packaged and shipped fast. Have made previous purchases from etrailer and will continue to do so.
think it gonna work great will be able to doo away with the cable valves
This is before installing. It arrived p romptly.
product purchase worked as needed to address the initial damage needing repair. service was excellent and product support was great.
Very easy replacement. Works just like it's supposed to.
Exactly as described
Arrived in less than a week. New, shiny and well made. Have not installed it on the camper as yet. Looks like the photo above.
Broke the old one on a rough non paved trailer truck turn around at a truck stop. Fortunately the tank was empty before the accident.
perfect fit, delivered on time !!!!
As always etrailer comes through with what I need and super fast shipping
You sent me the wrong part. I'm a disabled veteran and I've been in and out of the hospital for the last year and I never had a chance to return it
Parts were exactly as described. Fits perfect and easy to install. Quick delivery
After the initial horror of completely destroying my old dump valves, I shortly realized this was a thing and ready replacements were available. The biggest time sink was waiting for the blackwater tank to dry out and the only trick was getting a ABS pipe saw blade to cut the old gray and black water lines from the inside ($5 from any decent hardware store). The setting and gluing project was straightforward and the valves have been working perfectly since then - even better than the originals.
Very good quality, and fast shipping. Thank you!
Perfect fit! Thanks!!
The fit was perfect and it went on very easily. Especially on a 1986 fleetwod trailer I was worried that it wouldn’t work. Very nice product and service from E Trailer I have used them a lot.
Exactly what it shows to be
If you can DIY, etrailer is often the place that is priced most competitively of the pages of results that return on an [online] search but you go ahead and search the pages of results for confirmation. I got it when promised. It is for all practical purposes exactly like the one that I broke. Unfortunately I had to pay for fast shipping as a planned trip had to be delayed 5 days including 24hr leak test.[the dealer] did such a horrible install I used the time to gather parts to replace all of it and it seems more sturdy than the original. Something else very important when considering price, I had communication from etrailer each stage of the process that gets stuff to our door's. Thank you all so much and cheers to your continued success.
Great product, even better than the original! The rotating valve solved my alignment worries and makes it easier to open in that position. The original Valterra valve lasted more than 30 years, until I broke it. Love the DIY info and tutorials.

Still loving it! A sewer valve that works? Whats NOT to love?
The Parts I received matched up nearly perfect with the existing plumbing, that was ripper off when the inner duel blew out and took out all the piping along with the dump valves.

It’s been working very good, actual better than the original.
Looks like a good Valterra product. Shipped on time. Haven't installed it yet but plan to in the next week.
Was an exact replacement.
I ordered the wrong item but I was able to use some of the parts from the Y. I will save that for an emergency.
Fit was just perfect. I didn’t have to cut any of the old pipe.

Most excellently. No complaints. One thing I do recall is that multiple configurations of the assembly are available, be sure to order the right one.
