I bought this for a sewer bypass project to reclaim the washing machine and shower water for other uses. I have not had time to get this project up and running yet. I am certain that this bypass valve will work for this project.



by:

Great product and friendly staff, would highly recommend.Thanks Tammie in customer service.



by:

Took some adjustment to hanger straps, but the Manifold was a great replacement fit.



by:

I just received the product. It’s exactly what was advertised. Great product for the money. It is going to be a great replacement part for my travel trailer.



by:

Product was delivered as ordered. It was the part I needed and came in good packaging. It was easy to track the shipment as it came across country. This part will go into a trailer we are rehabing.



by:

This Product T18C worked great. I was able to change out my old Septic fitting and remove my Gray water outlet and combine it into this fitting and now I have one Septic outlet for my camper.
I highly recommend this product.



by:

I was pleased to see so many RV products available through this site. The part that I ordered was exactly what I needed to replace on our motorhome. Quick shipping was also a plus. Thanks!



by:

Exactly what we needed, and etrailer had it. No one else did. Had it to us in record time. Got our customer finished and on his way before Christmas! Love having etrailer on our team!



by:

We rent rvs and we had a customer break off the old drain pipe connection. Thought it would be harder to find but etrailers had this peice that was an exact fit! Great part, great fit, great results! Thanks etrailers!!



by:

The shipping was as promised, with the correct item. We actually lived in our camper for awhile this year during a home remodel so its gotten some heavy usage and is holding up well so far.



by:

Everything looks good and arrived on time thank you



by:

My etrailer buying experience was absolutely top shelf. From the moment I landed on the site I knew I was in good hands. I couldn't find exactly what I was looking for and when I called in, they spent a lot of time with me helping to locate the correct part. When I ordered the communication was excellent, in fact they shipped it quicker than expected. I ordered regular shipping and they upgraded me to express at no extra cost. I highly recommend etrailer and will absolutely be purchasing from them in the future.



by:

I just received the product today and at first glance it looks to be exactly what I need. I went to Home Depot and bought ABS pipe and ABS pipe glue, along with other connectors required for the gray water line, and hope to cut the ABS line to fit and complete the assembly and repair in the next few days. The product was purchased because my rear tire on my RV blew off its tread while driving, and the force of the tread splitting off knocked off my previous RV holding tank valve assembly and dropped it somewhere on the highway! Here is a photo after the original valve assembly broke off! Travel on!



by:

I put this on a 1980 trailer. It almost went right in. I had to extend the gray water inlet to fit up with the original mount location. It is very handy that this assembly pivots so I could easily align the discharge line from the gray water to the valve. I then just added a section of PVC to make up the short fall. I am very pleased with this manifold, valve assembly. It came complete with the gaskets.



by:

Great service, fast shipping.



by:

Went on easy and works great



by:

It was past time to replace existing waste valves. Black valve was ok but the flange holding the grey water valve was broken causing a grey water leak/drip.
Removing old valve and replacing was a little over a half hour; no leaks and no blood was spilled during installation.
Angela at etrailer was very helpful in making sure I order the correct part.

  • Replacement Waste Valve for 1990 Gulf Stream
    Hi Steph; all of the dimensions are the same on the T18 parts. The difference between them is the connection. The # T18 has a 3" hub that slides over your black water line and a 1-1/2" hub that slides over the gray water line. The A, B, and C have a mix of hubs and spigots. If you compare the # T18 to the # T18C in the picture below you can see the difference in the connections. The spigot slides into the lines instead of over. If your existing waste valve slides over both lines then the...

  • Replacement Double RV Waste Valve For a 2015 Nucamp 320s Camper
    Unfortunately Chris, I have no way to see which parts are installed on your 2015 Nucamp 320s. These double RV waste valves only have a few different designs so you will want to try and match yours with one from the list below. # T38 # T18A # TR38A # T80 # 34466NDHR19AAA # TR38B # 34466ND14AAR # T18C # T80A

  • Differences Between The Valterra Double Waste Valve # T18, # T18A, And # T18C
    Hey Dirk, I'd love to explain the difference, a spigot is essentially just the male fitting and hub is the female fitting. The spigot will slide into a hub fitting and can be glued in place with some abs cement # A05-0303. The # T18 has a 3" Hub and 1-1/2" Hub The # T18A has a 3" Spigot and 1-1/2" Hub The # T18C has a 3" Hub and 1-1/2" Spigot Each of these have a 90 degree angle for the gray tank connection to black tank connection so it's important to make sure this design lines...

  • Differences Between Valterra Double RV Waste Valves T18, T18A, and T18C
    The differences between the three Double Waste Valves you mentioned comes down to the differences between hubs and spigots for their fittings. Hubs fit over spigots. The part # T18 has a 3 inch hub and a 3 inch spigot. The part # T18A has a 3 inch spigot and a 1-1/2 inch hub The part # T18C has a 3 inch hub and a 1-1/2 inch spigot.

  • Replacement Seals and Hardware for 3" Valterra Waste Valves
    We have # T1003-7VP which is the older style 3” seal kit for valves made prior to 2000. But if you have a newer unit, you need part number # T1003-9VP that is the newer style 3” seal kit for current valves made after 2000.

  • Replacement Valterra Waste Valve for RV Gray Water Tank
    That is correct Larry and you sure can. The Double RV Waste Valves item # T18C has a a standard "T" shape and the Double RV Waste Valves item # TR38A branches of in a Y style angle. Both of them fit a 3" hub and 1-1/2" spigot. The Valterra Waste Valve for RV Gray Water Tank item # T1001B will replace the 1-1/2" waste valve on both the item # TR38A and item # T18C. It'll simple bolt in in place of the current one you have installed. It'll keep you from having to replace the entire assembly....

  • Replacement Sewage Waste Valves In a 1999 Coachman
    Great question. I can help you get what you need but I will need more information. Unlike vehicles RVs are not at universal and variations are common place.

  • Determining The Correct Replacement Waste Valve Fittings For A 20007 Keystone Trailer
    If you're looking to just replace the valves on your gray and black tanks then the Valterra Waste Valve Bodies w/ Flexible Cables for RV Black Water and Gray Water Tanks - 72" # TC1372 you were looking at would replace the valves. These valves bolt in-between two hub flanges. If your current valves don't have bolts and are glued in you would need different valves. If you send in some pics I can help find the correct fittings. If you're looking for a double waste valve like the Double...

  • Determining If Double RV Waste Valves # T18C Could Fit 2016 Coachmen Leprechaun
    The Double RV Waste Valves # T18C that you referenced is a very common valve on RVs like yours. Theres a good chance this is what you need. This slips over a 3 inch pipe on the bigger siade and the smaller side slips into the 1-1/2 inch pip.
