Our Grand Design camper survived the March '21 storm in Texas with just one broken water pipe. Evidenced by the over two month wait time before someone could repair it, we weren't the only ones with this problem.

I'm not a plumber, nor a professional videographer given the blurry video segments, but we decided to attempt to fix the broken line. Using comments from Grand Design Facebook groups and some great support from users on a Grand Design Owner's community site, we learned about using Pex pipe and connectors, how the Nautilus manifold works and came out of this we a much cheaper solution and one afternoon of repairing.

If you are a novice with PVC or can follow simple directions, you should be able to make these repairs to your camper's Nautilus control panel.

BnBmolders provided excellent installation directions for the Nautilus P4 Water panel: http://www.bandbmolders.com/index.php...

(A man named Rob Farrow shared a great pdf that was incredibly educational and useful for learning about PEX pipe and connectors. You have to join the community to download the PDF in this thread. Download it quickly before you get the unexpected 'permanent ban' for no reason, like I did. https://gdrvowners.com/forum/operatio... .)
