Video Transcript for A Closer Look at the Camco RV Gray-Water Drain Adapter w/ Seal
Today we're going taking a look at the Camco RV grey water drain adapter. Now this adapter lets you drain your RV's grey water tank at a campground dump station. The unit is actually a two piece design, two piece construction. The sponge is going to be the piece that fits tightly into the dump station inlet to provide an odor-tight, leak-proof seal. Does not require any tools. It's just a press and seal application so you just push it into the opening at the dump station. Then the adapter fits into the sponge and you press it down until it's tight.
That's going to provide the attachment point for the waste hose for your grey water tank. Not only does the unit allow you to drain the grey water tank but the sponge can be used separately. It can be used with a regular drain hose and other fittings as well. The opening here at the top that's going to give us a measurement of about three and one quarter of an inch. Here at the bottom that opening is about two and three quarters of an inch. Now on this adapter it's going to feature an easy gripper.
This is an easy gripper design. This easily threads onto the garden hose drain hose and has the appropriate internal seal for an airtight, odor-tight and leak-proof connection point. The unit's constructed of engineered grade resins to provide strength and durability. Products made in the USA. A few other measurements that I want to go over with you real quick. Just here at the sponge, I want to give you the outer diameter, edge to edge, that's going to be about four and seven eighths.
Outer diameter here on the bottom, edge to edge, is about three and three quarters of an inch. Overall height is only going to measure about two and one eighth of an inch, and then the thickness of that material is about three quarters of an inch thick. That's going to do it for today's look at the Camco RV grey water drain adapter.

Everything works fine. The only thing I would suggest is having some type of mechanism to ensure that it stays tight into the sewer connection. Such as changing the sponge material to an actual crew in material. Other than that, all is good.

This is exactly what I needed to secure a gray water hose in place. An added benefit is I can easily remove the gray segment and safely dump the liquids from my compost toilet. Because the hose attachment is slightly elevated and I am unable to create a continuous downward release, the flow from the van is initially slowed but eventually catches up.

Perfect answer for draining my gray water into the camp sewer system. Especially great for parks that do not allow the release of gray water into the environment. Attaches easily to the adaptor and hose I have on my Aliner.

Great product to use with our new tent trailer. We can use it for draining our gray water (kitchen sink/shower gray water) into a rv camping site dump connection. It works great.

Products are excellent. I love the instructional videos. Sales was helpful in sorting out what I needed. I won't ever waste my time and money on manufacturer's towing parts having done both. These were much nicer and easier to install.

- Can The Camco Drain Adapter Be Used With A Black Tank As Well?Hey Steve, The Camco Drain Adapter # CAM39322 can be used on your black tank with that standard hose fitting on it. You'll just want to make sure that the inlet of the dump station or drain is between 3-4" in diameter for this to fit. Otherwise it will work well for that application. How often are you able to get out in that Newmar?

view full answer... - Gray Water Hose Adapter for a 2014 Northstar ArrowA popular gray water hose adapter is # CAM39322. We also have the similar adapter # CAM39111 which is the same thing just without the seal part which is # CAM39313. These adapters will work well for you.
view full answer... - Will Using the Camco RV Gray-Water Drain Adapter Cause Odor To Get Into TrailerI would love to help but I am a bit confused by your question. The Camco RV Gray-Water Drain Adapter part # CAM39322 is an adapter that allows you to drain your gray water tank at a dump station. This in itself would not stop odor from traveling though your waste hose, into the gray tank, and then into your trailer but that is why you have p-traps on all of your drains. If this does not answer your question please clarify this further for me so I can better assist you.
