About this item
- 【Great Compatibility】 385318032 Vacuum Tank Switch Kit is compatible with Sealand / Dometic 729100 Vacuum Pump Kit. Compatible With Vacuum Tank Models: 317729100, 317729200, 317729400, 317324002, 385311660. Also suitable for the S pump and separate accumulator tank. Large O-ring that seals the switch flange to the tank is included.
- 【Perfect Design】 The resistance of coil is set to 8 to 10 inches. When the vacuum is being pulled into this chamber that diaphragm is pulled inward, pulling this way from trigger so that will turn the pump off. If the system is building enough vacuum but your switch is not responding to turn the pump off, maybe it’s time to upgrade your Vacuum Tank Switch.

- 【Easy & Fast Installation】 It takes a breeze to replace. Kit contains a vacuum switch and o-ring. Simply disconnect the wires, screw the replacement kit into the end of the tank with a 3” male pipe thread. Do everything in reverse and you’re ready to go!

The OEM switch assembly on my vacuum accumulator had a leak, and since I could not locate individual parts for it, I had to purchase the entire assembly. While this is not an official Dometic part, it fit perfectly and functions the same.Dometic stresses that the spring should never be adjusted since it is calibrated at the factory. I respect that, but I think that is important for brand-new systems. for those like me with a 30+ year old system, that is not feasible. I had to adjust the spring in order to fine-tune it, but that caused zero problems. This switch even has a metal bottom instead of the rubber one on the original. I like that, because this is where mine was leaking.I would happily recommend this product!
