Video Transcript for EZ Coupler 4-in-1 Threaded RV Sewer Adapter Review

Today we're going to be taking a look at the EZ Coupler four-in-one threaded RV sewer hose adapter with a 90-degree elbow fitting, part number F02-3305VP. You can pick up just the sewer adapter with part number F02-3103 or the threaded attachment with part number F02-3105. This threaded adapter makes it easy to connect your RV sewer hose to a dump station. It's going to work with your standard 3-inch RV sewer hose. It simply threads in place for a gas-tight fitting. There are no clamps or hardware required. With it in place, we have our slip fitting that can easily be attached to any dump station. It also includes an adapter with a 3-inch, 3.5-inch, and 4-inch thread should your dump station require it.

It simply slips in place over your slip fitting. The 90-degree elbow reduces stress on the hose by preventing it from bending. It features a 0.75-inch threaded fitting so you can connect a second gray water tank. When you're all done, you can remove the slip fitting and place on the drip cap for storage. Just a tip, when draining your tanks, you want to be sure and empty out your black water tank first, followed by your gray water tank. That will help flush out any remaining solid waste particles. That's going to complete our look at the EZ Coupler four-in-one threaded RV sewer adapter with a 90-degree elbow fitting.

This product has helped on a number of ways to hook up your sewer hose. Without the various attachments, I wouldnt of been able to dump at a few campgrounds Ive stayed at.

This is a good quality heavy gauge fitting.
by:
I've been RVing for over 14 years and sewer hose or parts get worn or broken. This past Spring (March) my end connection got stubborn when I packed up to put my RV in storage for the summer. I tapped on the connection and it immediately broke. So I've searched both RV stores and the internet for this end connection and found that this one fit my needs in both cost and it'll be ideal when I hook up again. It'll go allot better for me in that it comes in multiple pieces to fit multiple RV Park RV sewer connections. The catalog picture doesn't reflect the multiple hook ups. I also like the fact that this piece has a water hose connection for ease of flushing out the hose system. I'm looking forward to putting it to use

versatile fit for a replacement sewer adapter.

This is the perfect RV waste elbow. It's clear so you can see exactly what's happening as you dump, and also it's a one-piece unit. I HATE all the other two-piece units, the tiny little ears get sheared off trying to screw them in or out of the sewer ground connection, or they simply get unscrewed partially, then the top half pops off and it turns into a crappy situation!

Still working great, never leaks or comes loose!

We purchased a used washing machine and gas dryer that I converted to LPG. To keep neighbors happy I wanted to direct drain water into the septic system.

Happy to hear! Where do you have your permanent spot at?

by:
Second time ordering from etrailer. In both instances my items were shipped the same day that I ordered them, and I received them a few days later. Items were exactly as described. It is obvious that etrailer feels strongly about getting customers orders shipped as soon as possible and I appreciate that. Never had a problem with the items I ordered, so I can't speak to their customer service. I suspect however, that they will strongly stand behind the products they sell.
by:
These are awesome for monitoring the cleanliness of your waste tank but do not work well when the threaded connection is more than an inch below grade and concrete is sloped around the connection. The elbow threads could an inch or so taller. As with all RV trips, you may need an extension adapter.
