Sometimes connecting the hose to your RV city water inlet can be a challenge. Even if the connector looks like it is out in the open, it may not be easy to remove the cap and/or the hose once attached. That is why installing an aftermarket quick release connector or adapter to your water inlet is recommended. Doing so will make connection and disconnection from water sources a breeze.
These adapters come in a variety of styles and materials. Plastic ones are less expensive; however, the metal ones will last longer and are highly recommended. Some of the more expensive quick release adapters have both male and female connectors making it easy to connect to any hose no matter what the connector style is.
Quick Release Adapters for Your RV City water Inlet
Another option, though it is not a quick release adapter, it to install an elbow fitting, which easily twists onto the water inlet and can stay installed on the side of the unit at all times. This makes it easier to screw the hose onto the inlet.
If you are having difficulty removing the cap of the RV city water inlet it may be necessary to use some WD-40 to loosen things up a bit. Once removed, you can install an adapter or an elbow to make it easier to hook up to and disconnect from public water sources.
Your RV city water inlet is what brings pressurized water into your RV. That is why it is so important to ensure you get everything hooked up correctly. In addition to hooking up a quick release adapter, you may also want to include a water filter and a pressure regulator before connecting to your water supply.
How about hooking up to a filter first? Some “city” hookups are in small towns or even campgrounds.

Do they make a cover for the quick disconnect so that dirt and road debris doesn’t get into the city water fill? I saw the comment on the rubber stopper, but haven’t found anything that fits.

This is a great idea! Thank you for this content. I didn’t even know such a thing existed. It would be helpful to your users if you linked to the products, and beneficial to you if you have an Amazon affiliate account.
*Edit: I see further in the comments there are some links, but it would be easier to find in the description area.
Plastic vs brass quick disconnect:
I switched to hose quick disconnects some time ago for our two RVs (big for seasonal stays, quite small for ‘weekend trips’). I started out with lead-free brass but have migrated to quality plastic. Sure the brass is less likely to be damaged – but they are FAR more subjective to corrosion, not only making a watertight seal more difficult, but also making the disconnect sleeve harder to actuate. Sure I can coat parts with WD-40, but cringe at applying a petroleum based product on my potable water system. So long as they are not subject to abnormal abuse, the useful life of the plastic variety disconnect is longer – – and less expensive to replace if need be.
Hi guys do they sell the orings seperately? Or better yet include extra orings with it?
Hello Dean,
Thank you for contacting us.
You should be able to get the O-rings at local hardware stores for it, I don’t believe they come with extra ones. The newer style from Camco uses a different type of quick connect that doesn’t need O-rings from what I have seen. They do work well, here is a link to the newer style.

What’s the brand of the brass quick disconnects that you use in the video?
Hi Alan!
I wasn’t able to get the name of the ones specifically used in the video but I will share some links below to good commonly used quick connects.

I would recommend Gardena all metal quick connects. A little more expensive than brass or plastic, but non toxic, auto shutoff on disconnect, and easy to use. Worth every penny.
First I have concerns that you’re spraying WD-40 on a fresh water inlet. I recently purchased a brass quick disconnect fitting but then noticed it says “For garden use only”, as well as wash hands after handling, and “this product contains one or more chemicals known to the state of California to cause cancer and birth defects….” Are there specific quick disconnects that are drinking water safe, like the specific drinking water hoses?
Hi PJ,
Camco makes plastic and brass ones that were made for drinking water. I have included a link for more info and purchasing options. I hope this helps!

Gardena makes excellent all metal (non-toxic) quick connects. They also have plastic ones, but they are not as durable as the all metal connectors. I have been using the metal ones with great success and love them. They are durable, and form a secure connection that does not leak. They are expensive, but worth it.
Why would you ever spray WD40 on a water fitting? DUMB IDEA. this is your drinking water! nasty chemicals in parts per million and parts per billion with WD40. STOP this practice.
Hi Jim,
You are correct and I should have stated to be careful not to get it inside the connection. It would be better to use mineral oil or a food grade oil such as olive oil etc. Thanks for the catch!

You might use the brass right angle with the connection as well. Helps with reducing pressure on the fitting.
What about the wet road won’t they bring in contamination in to the system ?
Hello Alain,
That’s a good point! I typically have used this quick disconnect on units with the city water connection located in a compartment protected from the road, however our demo unit was the older type with an outside city connection. I would suggest either plugging the opening with a rubber stopper you can get at any home improvement store, or not using it in this situation. We will add a note to the video, again thanks for the comment!

Having a quick disconnect for the fresh water connection would be handy. But I am hesitant to add anything, even a quick disconnect, that makes my trailer more susceptible to damage from branches, etc. Is that something to worry about?
Hello Sam,
You shouldn’t have an issue with adding a quick disconnect to the side of your rig as it only adds about 1” with the typical indention of the city fill valve. If branches and other items get that close to the rig you’ll have problems with awnings, vents, and other items which would not be as solid as this?

I have found the L-shaped connector also reduces a kink in the hose at the city water connector. Also, I remove the L-connector when traveling. I may just leave it on from now on as I don’t believe that a danger of theft can occur while traveling. I may look at getting a quick disconnect to attach to the L-shaped connector.
Where can you purchase the quick release adaptor
Thanks for visiting the RV Repair Club site, the quick release adapter can be purchased at and RV dealer or parts provider and at most home improvement centers such as Lowe’s and Home Depot. I’ve also found them at hardware stores like Ace and True Value and recently even at WalMart!
Hope this helps, and happy camping.
