Features to know about

Keep Everything Clean and Together: Compact Recessed Docking Station

This isn't a bunch of loose inlets scattered around your rig - this docking station keeps all your essential hookups in one tidy, recessed panel built right into your RV's wall. A thumb-latch door protects everything when not in use, and built-in gates let you close the door even with hoses connected. That means your setup stays clean, and your connections stay protected, all while keeping the outside of your rig neat.

Simplify Your Water Routine: Dual-Use Water Inlet with Flip Switch

Whether you're hooked up at a campsite or preparing for off-grid travel, you can switch between using city water and filling your RV's fresh-water tank just by flipping a switch. No crawling around to reroute hoses. Just hook up once and choose the mode that fits your day. It's quick, it's simple, and it makes camp setup easier every time.

Simplify Cold-Weather Prep: Dedicated Winterize Port

Getting your RV ready for freezing temps doesn't have to be a hassle. This docking station includes a dedicated winterizing port so you can easily introduce antifreeze into your water system or blow out the lines with compressed air. It's a faster, cleaner way to protect your plumbing before storage or cold-weather travel.

Reliable Water Safety: Check Valves Built Into Inlets

Both water inlets are equipped with check valves that prevent water from backflowing into your hose. It's one of those details you don't always see but makes a difference in keeping your water supply clean and your setup worry-free.

Video Transcript for Review of B and B Molders RV Water Inlets - City Fill Inlet - BM22GR

Hi everyone, Steve here with etrailer.com. Today, we're looking together at this B&B Mini RV Water Set here. It's a city tank fill. You can winterize it, sanitize, shower pump switches are included. It's a great all-in-one compact recess design. So this one's installed flush inside your RV wall.

You have included key here for locking it and you do get one key, and you can buy extra, sold separately once you get it with the key number that you have, or you can do, you know, other keys, it's made to be key to like whenever you get it and everything. Buy a Global Link, that's the brand of that key and lock. As you can see, you got the door, then you got your main shutoff and everything here. Just like the instruction show you, you can switch from fill tank to city water, so that's what that lever is for. And then, of course, your different connections, your light switches, and the pump switch, everything included, and you even have a little popup door here.

That way whenever you have that hose or whatever connected, now, you can slide this door open, still lock it, that way no one can come around and unhook your connections. On the backside, you have all those different connections and plastic connectors and whatnot for everything to connect to. They even give you a inline filter with included rubber washer and a roll of butyl tape for installation. Now, butyl tape, if you never used it, it's kinda like a putty, it's really squishy. You're gonna put that on the outside here on that cutout and then with the included screws that are painted black to match, you're gonna install that on the cutout.

This cutout measures six inches long by four and seven eighths tall. The front of the product measures seven and five eighths overall by six and a half tall, and if you did not include none of these pipes and everything, just here to the front is two and one eighth inches deep. So folks, this is a great addition or a replacement, if you need one. The B&B Mini RV Water Center. I'm Steven, thanks for watching, and have a great day.

Thank you for the kind words! We're happy to assist you with any of your trailer needs in the future :)

Looks to be a direct replacement for current unit. Good kit that comes with all parts needed to install. Excellent tracking on order and communication on short back-order delay. Thanks
by:
I was disappointed with this one. Despite use of Teflon tape on the threaded connections the one that I received leaked like a sieve. I ordered another similar replacement from etrailer, B & B Moulders Model BM83RR which has brass instead of plastic threads.
by:
I ordered as a replacement part for my 1999 Jayco 5th wheel. Fit perfectly and very pleased with the results!
by:
so far so good, the valve was installed and has worked as expected, it was the most optioned and expensive available with 3 different valves/uses and a locking exterior door and has worked as advertised.
by:
Overall nice product. Minor grumbles include: only one key, the latch could be improved (it’s a bit tight latching) and lastly, they place a gooey sticker on the door promoting the ability to key alike. I peeled it off the pebble finish and it left a gooey mess. Ugh.


Etrailer- first rate. Five stars…..
by:
It looks perfect it was difficult to find as the product is referred to as several names. Connections box water box ect. This is what I was looking for and it arrived really fast. I wish the trailer company here had told me that I could simply replace the guts and not spend $275 for the entire unit thats on me but telling me 8 weeks from products ordered out of the states is BS. etrailer has been great it arrived within the week across the boarder with no issues.
Thanks
by:
Thank you for having the part we needed at a fair price and fast shipping, this was not a common part and had variances in different models, you had the exact one we needed. thanks again
by:
I'm not impressed without the to just replace the check valve only. For reasons of needing the trailer up and running ASAP, I bought the poor designed product. I will be modifying my old one to be able to repair easily and be a sustainable product, instead of the wasteful use that ends up in a landfill.
by:
Exact replacement needed for my customers RV. Quality was great and came fast! It does not come with a lock and key like the one previously installed but was able to swap the doors from the old one. Also comes with a small amount of butyl tape.
by:
Have always been very helpful and products have been reliable.
by:
We appreciate etrailer having what we needed to fix a camper. we were working on. Look forward to doing more business with you in the future recommend etrailer to anyone that would need an RV part. Thank you.
by:
Much better than the original that came on my trailer. It was an exact fit to the opening with even the screw holes aligning. And most importantly it has been 100% leak free with daily use over the past couple of weeks. It’s a solid replacement product.
by:
Exact replacement for my camplite travel trailer.
by:
Dwight isvinstalling it today a perfect match!

Recived the Item #BM58MR quickly, estimate was a Friday about a week. I recieved it three days after ordering. The description and measurements given matched exactly. Came with all items necessary to install. Installation took about thirty minutes (your mileage may vary) i work slowly. Quality of the materials that the part is made of appear of good to excellent quality. Overall it was fantastic to find your company carried the product, and it was made of good materials. I will be looking to etrailer for any rv parts i may need. Thanks for reading this review, your looking in the right place.
