The Dometic/Sealand 385318032 Vacuum Tank Switch is an essential component designed for accumulator-style (threaded) tanks in marine sanitation systems. This switch is primarily used when issues arise with the vacuum switch generator, such as when the generator does not shut off despite a sufficient vacuum in the toilet. This indicates a potential problem with the vacuum tank switch, making the Dometic/Sealand 385318032 a top choice for replacement.

Key features of this vacuum tank switch include:

• Compatibility with the original vacuum accumulator tank.
• Easy installation as it screws into the end of the tank using a 3" male pipe thread.
• Inclusion of a new "O" ring that ensures a proper seal between the switch flange and the tank.

The switch is factory preset, ensuring it works optimally right out of the box. However, it is important to note that this assembly does not include a cap/switch cover. The switch's design and functionality make it a reliable and efficient choice for maintaining the proper operation of your vacuum system in marine toilets.
