Video Transcript for Review of B and B Molders Replacement 2 Way Diverter Valve Assembly - BM48GR

Hello, neighbors, Steven here with etrailer.com. Today we're looking at a replacement 2-way diverter valve assembly for your B&B RV Nautilus P1 and P3 panels. Now folks, this does replace a single 2-way diverter valve plumbing assembly on your B&B RV Nautilus water control panel. Now it does replace damaged diverter assemblies on the P1 and P3 models. I'll put those model numbers on the site there so you can see 'em. Now you're gonna get quantity one diverter assembly here.

It has two half-inch MPT, or male pipe thread, fittings, and it's gonna work with the P2 and P3 units, or P1 and P3 rather. And all plumbing connections sit behind the panel, and the diverter assembly mounts integrally directly with the panel itself. Now as far as some dimensions on this guy. Overall, side to side, I was getting right at 5 1/2 inches long, 4 3/4 on center on those MPT fittings, and then, when it comes to these mounting holes here, this way and this way, this way, I was getting right at 1 inch on center, while, this way, I was getting right at 1 1/8 inch on center. So, again, folks, this is the replacement 2-way diverter valve assembly.

I'm Steven. Thanks for watching. And have a great day.
