B&B Nautilus P2.5 RV Multifunction Water Fill Panel | Black | USA

Centralize your RV water system controls with the B&B Nautilus P2.5 H2O System Multifunction City Water Fill Panel (Black). Consolidates fresh water tank fill, city water hookup, winterization, and black tank rinse into a single, easy-to-find control panel. Made in USA.

What This Panel Does

The Nautilus P2.5 is a central control hub for your RV's water system — replacing the confusion of scattered valves, ports, and switches with a single unified panel:

• Power fill your fresh water tank — for dry camping
• Pump water from fresh tank to your fixtures
• Siphon fill or sanitize the fresh water tank from a bucket using the pump
• Connect to city water at the campsite to supply fixtures
• Winterize plumbing lines and fixtures — antifreeze routing built in
• Rinse black tank — helps control odors and prevent sewage buildup
