Video Transcript for EZ Coupler RV Sewer F02-3106CL Review

Speaker 1: Today we're taking a look at the EZ Coupler Cap from Valterra. This is a valve cap that fits a standard 3" waste valve. It features a built-in handle for easy operation, so it allows you to easily install it and remove it from the actual waste valve. It also features a 3/4" gray water drain. Now, this product is made from a durable plastic construction. It's clear when it comes to the coloring, it does already feature the installed seals, so it's going to ensure leak-proof connections, and it comes with two tethers to keep the caps close by, so you don't misplace them or lose them.

One right here is for the main drain cap and then the other tether is for the gray water drain cap, the 3/4" water drain.That's going to do it for today's look at the EZ Coupler Cap from Valterra.

EZ Coupler Cap for RV Waste Valve w/ Handle and Gray Water Drain - Clear - F02-3106CL

Average Customer Rating:  4.9 out of 5 stars   (50 Customer Reviews)


I got this to add vegetable oil via a short hose to lubricate the drain valve.
The handle makes removing the cap a snap. I already had one of these in black for everyday use. No more kneeling on the ground to reach the awkward cap.


I replaced a similar black cracked ABS cap. I like the feature that you can see what is in the drain pipe. I added a small hose drain valve to the cap so I can relieve pressure build up or drain a minor amount of waste fluid into the drain hose before opening up the cap(valve cuts down on surprises).


So much easier to remove cap. Highy re commend.


For my set up the drain is not at the bottom, it’s a little to the side which is annoying.


Love it! As a single woman pulling a trailer, my hands are not big or strong enough to easily take the sewer cap off so it is quite a process. This item makes everything sooooo easy.


Not very glamorous as products go, but extremely strong, and well designed; and perhaps the highest praise I can offer for a sewage product, it does what it's supposed to do.



A big fear among many RV owners have is opening that port and finding out that one of the valves has been leaking and you now have a mess that you could have prepared for had a bucket if youd known. This cap gives you that knowledge. Im thankful its never happened to me, but Ive seen and smelled it and never want to be the cause. The cap is well made and will probably last as long as the RV.


Exactly what I was looking for. Excellent product and Fast shipping!


Easy to attach, and it fit fine. Nothing different than what I expected when I ordered it.


Bought two because previous caps kept breaking the ears off. So far I have yet to break an ear and it’s nice to be able to see that the line is empty Before removing cap.


This is probably the most useful item I ever purchased. It meets the three needs for a sewer cap: 1) it’s easy to take off; 2) you can see if you have any leakage; and 3) you have an easy way to drain the pipe without creating a mess.


Great item to have.


The Item functionally is great. The handle makes it easy to twist on and remove. The item was substituted because it did not have the eTrailer printed on the handle, but functionally it is the same. seems sturdy, but time will tell. I really love the handle since without it, it is difficult for me to twist on and off a cap without this added feature.


Works just like a normal cover, but the hose connection allows connection of a garden hose in case the distance to a dump is longer than your normal accordion. Should only be used for gray water.


Quality product, exactly what I needed. Would purchase again.



Seals have held up! Fits very tightly around drain so it doesn’t fall off. Have used male hose fitting and it works well


Looks good


Great thing to have. I had an incident where the black tank valve was cracked open and when i went to hook up the hose.... Well it wasnt the best situation. LOL

This will allow me to see if anything is in the drain line and it has a way for me to drain anything that might be in the line without getting dirty.


With the designed handle it is so much easier to remove the cap. The clear plastic provides a quick way to check for liquid prior to removing the cap.


I've been putting up with my leaky old cap that was both hard to put on and take off. This new cap is fantastic tic from the big grip handle to the hose drain, to the great seal. I definitely recommend this product.


It is what it said it is. I love not having to grab the body. Greatly decreases the potential to get black water on my gloves.


Great idea and product. Solved several problems for us, especially taking it off and on


Works great when I am pumping my grey water into a barrel.


I am very happy with your product. It ws just as the it said it would be. It wfits and works on the trailer very well. I will shop from you again.


Great service, just what I wanted



works great


Works as one would expect and allows you to see if there is any liquid in there before you open it.


Constructed much better than factory cap which broke.
