Video Transcript for An In-Depth Look at the EZ Coupler Cap for RV Waste Valve w/ Handle and Gray Water Drain

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.

You can clearly see if there are any surprises before opening. Easy twist off handle. Gray water drain easily monitored. Everything you needed in a sewer cap but were afraid to ask for.

Glad we could help, Richard! It's always funny how so small a thing can make such a difference. ^___^ What's the next trip you have planned?

LOVE THE HANDLE
by:
I have arthritis in my hands and this is a GAME CHANGER!! Love it! It is so easy to open. Thank you thank you thank you.
by:
In my initial attaching of these caps I love them very much! The large handle is easy to reach and turn - Quite difficult to get the standard kind off without "2 handing" it.
by:
Now I open the Rv dump line with ease. Saves time, cleaner to open and no surprises.
by:
Great part. I didn't have any trouble placing it and removing it, compared to the one that came with my RV. I haven't taken the vehicle on the road yet, so I still have to see how it survives the ride.
by:
I have found that the products you send are always as detailed on your web site, communication is very good and always arrives as scheduled. Thank you!

Fast delivery

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.

These thing are a game changer. I originally bought it because I have a hard time bending over enough to reach under for the original cap. The new caps with a handle makes it a breeze. I also added a clear 45 deg. extension on my hose, and its now easy. But, the beauty of the cap is having a 34 hose fitting, I can use a section of hose with a funnel and add lubricant to the tank valves while theyre closed or open and I dont dump it on the ground. Your funnel just has to be above the level in the tank. Easy.

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).

The transparent caps are working well and allow me to see any and how much fluid is still in the piping to allow for connection without the black or grey water shower.

by:
I bought this to replace my previous cap which only had 2 ears and 1 of them broke off. I wanted to replace it with one that has 4 things... 4 ears, a handle to grab to install/uninstall, clear so you can see what's going on, and it has the 3/4" garden hose fitting to dump grey water. This one has all 4!!! The only thing I would change is the photos, it looks frosted, but it really is completely clear so you CAN see the water inside.
by:
Delivered fast as always.
by:
Sturdy construction. Easy to use. The handle provides a good grip for removing & reinstalling the valve cover. I’d recommend this to replace stock valve covers since the stock covers provide virtually no grip surface to twist them on & off.
by:
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.
by:
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.
by:
Very easy to install. High quality product. No more “wet surprises” from now on!
by:
It leaks. I'd first bought one from Amazon and it leaked, so I spent a whole lot more money on this one thinking that if I paid more I'd get one that didn't leak. I was wrong. Yet again more $$$ doesn't equal better quality.

Sorry to hear that Donald, Parts like this with seals and gaskets can be sensitive installs. There's a few things to check: Making sure the rubber gasket is seated flat and not twisted on the coupler Not overtightening the mounting screws Check the inlet thread since leaks sometimes appear to come from the body but are actually from the connections Inspect the clear bowl carefully for hairline cracks around the threads If it's none of the above, then you could have a defective unit and we can assist with that.

by:
We haven’t had a chance to use it while traveling yet. It looks like it’s going to be just great though! Thank you.
by:
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.
by:
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.
by:
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.
by:
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.
by:
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.
