Hi, everybody, Andy here with etrailer.com. Let's take a real quick look at this B&B Black RV City Water Inlet. Now, this city water fill with check valve is going to replace a leaking or damaged valve on your RV. The check valve is going to prevent backflow into the city's system when under pressure, and this lead-free, brass is not going to rust or contaminate incoming water. And this removable screen right here, that's a little filter that's gonna be very easy to clean and replace. The cutout required for this is going to be 1 1/2 inches in diameter.
That rear water connection is a 1/2 an inch NPT, and let me see if I can show you the flange diameter. So, as you can see, we are sitting right at three inches on the flange, outer diameter. And then the depth, we are sitting right at about 1 11/16 inches on the valve depth. This grip collar is going to let you easily attach and detach your hose. This tethered plug is going to protect this fill point when it's not in use.
You just pop it into place just like that. And this is made here in the USA of corrosion-proof plastic. It's UV-stabilized plastic, so you're not gonna have to worry about this fading. It's gonna hold up really well against the elements. This does include the mounting hardware and butyl tape.
This is NSF, IAPMO, CSA and TEI certified. Well, I think that's gonna wrap up our real quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

Sorry to hear that, Roger. I would have thought the pipe this fitting attached to would have held everything in place better. I will be forwarding your picture over to B&B Molders to see if they can maybe start doing something to strengthen this part. What did you install this on?

Still works perfectly. Havent even given it a thought. The large knurled plastic knob extension makes turning the fitting very easy. The knurled knob is a slip fit over the fitting so I have pulled it off a few times by accident but it slides right back right into place so no biggie.
Do you have a question about this RV Water Inlet?

Looks great, Kailin! How long have you been doing mobile grooming? I think the whole idea of it is pretty cool :)
