RV sanitation tee combines rotating black-water and gray-water waste valves. 3" Hub slides over black-water line. 1-1/2" Hub slides over gray-water line. Bayonet cap fits over 3" lug fitting that connects to your sewer hose.
Features:
This RV sanitation tee with double rotating valves is a part of your motor home's waste management system. The T-configuration combines the flow of wastewater from your gray-water tank and your black-water tank. And the valves can be rotated as desired during setup to make it easier to reach them. Connect your sewer hose to the 3" lug fitting on the sanitation tee and open the valves to drain your holding tanks.
Ratings & Reviews
Excellent quality, fit great works perf ect.
I am extremely pleased with the waste value i ordered from etrailer. It arrived on scheduled delivery date. For some reason UPS transferred the package to my local USPS instead of delivering it themselves, so I did have to pick it up since it was to large for our mailbox.
Part was correct and good quality. It took 15 days to get part from the day I ordered it. It was over a week before it was shipped. That delay was longer than anyone else I deal with. If there was a problem I should have been notified.
!!!!!!!!!!!!!!!!!!!
This thing still works great after a year of use. It was easy to install and the slides are still smooth and easy to use. Thanks for a great, reasonably priced product.
have not had a chance to install yet. however looks good as a replacement.
This is a fantastic valve. It fit perfect. no modifications.
Product was as advertised and an exact replacement
The dual valve is exactly what I needed. It is identical to the OEM valve that came with my RV. I am very pleased with the overall quality and the speed with which the part was shipped to me!
shipping A+ product A+ expierence A+
Good product and good pricing. Staff was responsive and respecful. I will be using ETrailer again. Product is made well.
Exactly as described and pictured. Quick shipping was GREAT !!
Thank you.
My previous valve assembly was damaged when the temperature at Elk camp dropped below 20 degrees. This new valve bolted right on and stopped the dripping that was happening. The best part is that it survived the 2020 Elk camp!
Heavy duty valves, it is a Valterra product. I’ve installed every kind of waste valves made and now we use Valterra exclusively.
Had a blowout that wiped out the grey/black dump valves, along with a lot of other damage. This is a simple direct replacement for the 10 year old OEM installed valves. Saved lots of time & money. The rep at e/trailer (angela k.) was awesome to work with.
The product was great. Even though I don't know about plumbing the description and video tell you the measurements. But I didn't realize the 3" pvc pipe for fit directly into it. And I needed a 2" coupler for the 1 1/2 side. But once I figured that out it was quick repair for my vintage trailer.
This was shipped very quickly, and the price was great. Comes with both the large and small "input side" flanges, which I didn't actually need because it was a replacement for an existing valve set, but then you get all the new screws and gaskets too. Simple to replace my existing valves, where were cracked and leaking from road abuse.
Thanks etrailer!
Not quite what I was expecting based on the photos (1-1/2" inlet attached to 3" drain fitting slightly different than the old part) but it bolted up just fine, and as an added bonus the black tank 3" valve does not appear to leak like my old one did right from the factory.
Did a replacement of my grey and black water stopper valves. The seal of the black tank started leaking. So I purchased the new one came fairly quick. It was easy to replace doing all the work myself. Only taking up one afternoon of my time. I’m liking the ease of operation. I’m very happy with it’s turn out. Thanks
Product works as intended, easy installation. If you are mounting on an older camper, beware that the manufacturer used steel bolts that rust. you don't want to snap off the plastic valve flange when installing. Other than that, product works beautifully.
It's the right part, at the best price. Great service. Now I just have to install it. Thank you,
You guys did a wonderful job !!
From your easy website to the outstanding young lady I talked with about my order. WOW !!!! the order was exactly perfect and in the time frame it was promised.. great job!!
Thanks
My 2013 27/20 Trailmanor camper had separate discharges for gray water and sewage and I bought this to combine both discharges. It works fine as it has in previous TrailManor models prior to them going to separate discharges.

No problems at all, valve works very well
The previous owner did some very odd plumbing. I don't think they ever heard the saying that 'stuff only runs downhill'. For some unknown reason they put a 45 deg angle on the exit pipes which turned the waste valves pointing up. This new waste valve and some new junction pieces was just the ticket to get my rig back and draining properly. Valve was easy to position and install.
I wanted to get rid of a leaking black tank valve and get rid of two cables that operate the gray and black valves. All the black pvc and this valve was the perfect solution. I was able to decide the perfect position for every thing. I am not a plumber, just a diy guy. I will be posting on the Grand Design 23lde facebook page more details.

Excellent. I would agree with George Jthe original bolts can be a problem if they are rusted mostly likely they aresome may need to be hacksawed off, so be careful. If you can get the old off cleanly, its a perfect fit as far as assembly and installation.
