Video Transcript for Let’s Check Out the Replacement Diverter Valve Assembly for B and B Nautilus P4 Panel

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this B&B Replacement Diverter Valve Assembly. This is going to replace a single diverter valve plumbing assembly on your B&B RV Nautilus P4 water control panel. On your screen, I am including the model numbers of those P4 water control panels that this is going to fit. This does consist of one diverter valve T-fitting assembly with half-inch MPT fittings for your P4 unit.

All plumbing connections, as you no doubt know, sit behind the panel, and this diverter assembly integrates directly with that panel. This is the direct replacement from B&B, so you can trust that this is going to fit right in place of that original assembly. You're not gonna have to worry about fitment issues, compatibility issues, or anything like that. Well, I think that's going to wrap up our brief look today. I do hope that it was helpful for you.

Again, my name is Andy, thank you for joining me.
