Video Transcript for Review of B and B Molders Replacement RV Plastic Check Valve with Clip - BM46MR

Hello neighbors, Steven here with etrailer.com. Today we're looking at a replacement RV plastic check valve with the clip for your B&B motors city water inlets. Now, folks, this is a simple replacement part direct from B&B so you can ensure it's gonna fit those B&B city RV water fills. You're gonna get the whole assembly here with the included internal check valve; it's inside of there already. You get the screen, you get the right cap here. Holds everything in place.

And then when you put it in, you have a nice retainer clip here that holds it in place. It prevents water from back flowing into your pressurized water system. And it works with your standard equipment for the city fill, so like washing dishes, plate attaches, that kind of stuff, and you get everything you see before you. Now that being said, it does fit again into those B&B motors city water inlets. I went ahead and pulled one.

This is sold separately, but I wanna kind of show you how this whole thing goes together. So here's what one looks like. And it's gonna go right here. So this one here is your main huge water gravity fill port. But this guy here is gonna go in here, and then once you got it in place, on the back, you'll just simply slide this clip all the way down in place and that'll hold it in place.

So a simple install. That's what it looks like when it's installed. So, once again, folks, you're gonna get everything you see here; just the whole assembly with the clip. Folks, I'm Steven. That's gonna wrap it up today for a look at this.

Thanks for watching with me and have a great day.

I was impressed with the quick response to my order regarding the correct delivery address, then a follow up there next morning if the tracking number. What I really thought added a special level up of service were the names with photos (!) of the employees responsible for each step of the process, in case I had questions and needed to contact someone. No problem, here’s their name and contact info. Amazon and Apple should take note!

The product is exactly what was needed for a water panel repair, however as a full-time RVer, I was completely out of water for an extra day because the described part arrived a day later than advertised, despite paying the premium for expedited shipment.



by:

the product is of good quality. Shipping was very slow thanks to a mistake made by the USPS sending it to Massachusetts, then Connecticut then Des Moines, Iowa before sending to Jackson Missouri.



by:
