Today we're going to be taking a look at the Valterra RV Waste Valve with the included cap and tether. The unit simply adds, or replaces a waste valve in your RV's waste system. It's made from a strong, and durable black plastic construction. Here on this end we're going to have the cap and tether. The tether design is nice, because it keeps the cap from being misplaced or lost. Always keeps it connected.
Now you'll notice on this side that it's going to have the male threaded pipe. This is going to give us an outer diameter measuring outer thread to outer thread pretty close to one and seven eighths of an inch. Internal, which is inside edge to inside edge that going to give us a diameter of about one and seven sixteenths of an inch. One the other end this is going to give us an diameter measurement of about one and seven eighths of an inch, inner diameter is going to measure about one and nine sixteenths of an inch. It's designed for an inch and half pipe. On top we're going to have the easily accessible T-handle.
It makes opening, and closing the gate quick and easy. It's going to be gray in color. The unit is already assembled. It has the appropriate seals internally that's installed for leak-proof performance. Let me put the cap back on, and then we can go over a few more measurements.
I'm going to give you a length measurement with the handle in the closed position. That's going to give us a measurement of about six and three quarters of an inch. Then if we extend that out, and do that same measurement we're lookin' at about eight and three quarters of an inch. That's going to do it for today's look at the Valterra RV Waste Valve with the cap and tether.

Delivery was 2 days ahead of time and correct part. Great quality.
Excellent product. Had to wait awhile but well worth the wait. Been having trouble with black tank valve leaking by. Called and it would be July until our dealer could check it out. This will be a permanent fixture on my Fifth Wheel. Thanks etrailer for getting it to me.
Etrailer seems to be the only company that I can get things for my trailer at a reasonable price and reasonable time. Thank you guys!!!
The product really helps with my dump station duties. At age 81 I find it hard to reach the tank valves which are way under the trailer. This unit extends the valve assembly and makes it easier to reach. I have had a problem with attaching a built in position clamp which is behind the unit. Consequently, the unit has a tendency to rotate and is not locked in position. This problem is easily solved if I lie down under the trailer which I don't want to do. I'm glad I bought this valve because it solves the problem of ease of use for me.
Using this attached to my Y on the Black and Grey connection. It works great! Heavy duty! Worth the money.
etrailer customer service is exceptional. They shipped me the wrong item. However, I called on Saturday they immediately sent the correct item and I had it on Wednesday!!! Then they called to confirm the problem was resolved and I was satisfied.
It’s a nice valve. I would like it better if there was someway to lock the handle at a given orientation. For instance, I’d like the pull handle to remain in the 3:00 position. Unfortunately I can’t figure out how to do that as it will rotate after being installed.
This was an easy install and does prevent any leaks from the black tank or grey tank valves (if they leak) from escaping when the dump cap is removed to hook up the dump hose. I noted that the new valve can be removed without too much effort; however, there is a pin to insert in one of the bayonet hooks to prevent this from occurring. I think it is robust enough not to break while experiencing the vibrations during travel. If I do get concerned, I will supplement the bayonet connections with some tape or other means. I also noted that the dump cap installed on the end of the new Valterra Twist On valve twists off a bit easier than the cap on the original dump tube. I took the dump cap off several times to see if the new Valterra valve would twist off instead of the cap. This never happened; however, given I only need one hand now to twist off the cap, I will probable always hold the valve when taking off the cap to prevent the valve from possibly twisting as well as to relieve any stress I might put on the pin at the connection point. To verify the new valve connection was leak tight, I put water in the grey tank and opened the grey tank valve with the new Valterra valve closed. There were no leaks. The Valterra valve is installed on a Class B van with low ground clearance. Given the handle can swivel to provide flexibility, I will probable secure the handle to the undercarriage of the van to prevent the handle from swiveling down and possibly reducing ground clearance. I don't know if this would/could happen, but I don't want to find out the hard way. Overall, I'm very satisfied with the purchase.
excellent quality and very fast delivery nice!!!!!
I am using the for a flush drain for my tuna bleed barrel. And fast delivery. Mark
It has done its job so far, no leaks so far after a year.
I buy a lot of these and they work great, after a year i usually put a little lube on the gate valve. The only time they go bad is when they get hit.
GREAT DRAIN VALVE, MIGHT HAVE TO LUBE WITH SILICONE ONCE A YEAR DEPENDING HOW MUCH USE.
Excellent quality, packaged very well. Arrived sooner than expected! Great online service for parts. Parts will be used to separate black water from grey water, black water to septic, grey water to tank for other uses. Thanks again,
Drips from behind the rubber gasket after one year. The plastic seems like it has become brittle from the weather I guess?
Appears well made and outside diameter of slip fitting fits nicely. Cap tether pivots as not to break from repeated use, although recommend taking the time to support the tether when unscrewing the cap.
Had difficulty locating a 1-1/2” waste slide gate valve with a threaded end and slip fitting on the internet. I custom made living quarters in the front section of my GN horse trailer. The park where I take horses camping frowns deeply on discharging grey water from my showe and sink on the ground (although it is ok to wash horses..go figure) so had to plumb in a drain system. This valve will allow me to make a connection to a portable grey wastewater tank.
I’d share pictures but haven’t installed the drain system, just received all the fittings to do so.
Great product, if they get hard to open or close a little silicon lube every now and then keeps them working smoothly.
The parts are excellent, but it took two weeks to receive them. That really delayed my project.
Do you have a question about this RV Waste Valve?
