B&B Molders Nautilus P3 94145 Water Panel — Parts Diagram

The B&B Molders Nautilus P3 has its own factory-numbered water-management drawing. Its white panel assembly is 94145 (OEM reference 301-041-00001). The panel manages city-water service, tank filling, tank-fed supply, winterizing and tank flushing, but it is not the same as the P1 panel. The diverter layout is different, so follow the P3 drawing numbers when replacing an individual valve.

Nautilus P3 replacement parts by drawing number

Find the numbered part on the manufacturer's P3 front-and-rear illustration, then compare its shape and connections with the original. The factory list uses number 10 for the valve and two related spacers; they are shown separately here so the pieces are not confused.

Identify the P3 water-control components

At P3 position 8, 94136 is the diverter operated by the green handle. Number 9 is a different diverter (94389), and number 10 identifies the 94387 blue/white-handle diverter along with spacers 94388 and 94386. Check those exact numbers instead of choosing a valve by color alone.

The faucet at position 11 is 94140; the city-water connection at 13 is 94210. Both products have separate photographs and listings below.

Manufacturer diagram and fit checks

Open the B&B Molders manufacturer parts catalog (PDF). The Nautilus water-management drawings are in the plumbing section; use the numbered original front-and-rear views to locate each component.

Identify your panel before ordering. The P1 and P3 systems have different factory diagrams, and a shared valve number does not mean all handles and diverters interchange. Compare the model label, valve body, handle position and surrounding connections. Diagram positions identify service components; they do not indicate what is supplied with a complete panel.

Have a P1 system instead? Use the separate Nautilus P1 parts guide; its 94135 and 94137 valves are not assigned to these P3 drawing positions.
