Fits the original Vacuum Accumulator Tank, "O" ring included.
*Installation Tip: Power wires are connected to the "B: Terminals, Soap or Light Grease on O'Ring
*Service Tip: You have good vacuum but the pump continues to run its likely that the Vacuum Switch is bad or a major vacuum leak.
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.

Easy install
Just as previous reviews...easy install and fixed my pump shut-off problem
the pump still runs a bit long to build the vacuum so I probably will need to refurbish some pump parts too -
Not adjusted right out of box
I had to pay someone $20.00 to come over and adjust the switch because it would not shut off. I installed it right out of the box. Was told one time we could not adjust it and it would have to be sent back. Had to get it working due to seatrial the next day.

The vacuum switches are calibrated units, If after you install it and the pump does not shut off you have other problems, Adjusting the switch does not solve the problem. -
Great Product - George was a Star
The Vacuum Switch was a snap to change. Just take to wires off switch, screw off old, put a little liquid soap on "o" ring and screw on new, put the 2 wires back on and all done. Works like new. George said it would be easy and no adjustments and thats how it was. Thanks George.

Great Knowledge and support - works as adveritsed
I spoke with George's son and purchased a rebuild kit and then the Vacuum switch. Both times, I told him my issues and he diagnosed it immediately. The product shipped same day (free shipping) and was easy to swap out with my old one. Just make sure that you connect the wires the same way as before.
Thanks!!!!
Additionally, I asked if I needed another seal kit for my old system. He very easily could have said yes but said that I wouldn't need that product as it rarely fails. Sure enough, he was right and it wasn't needed. You will always be my go to people for anything vacuflush. -
