Good As New If the system is building enough vacuum but your switch is not responding to turn the pump off. Simply replace your old switch with our upgraded vacuum tank switch kit, it will constantly monitor the vacuum level and energize the pump when there's a drop in vacuum level due to flushing. Note Installs by threading into the tank.
Premium Material Precise CNC process manufacturing ensures a snug fit for the Dometic SeaLand vacuum tank. The 385318032 vacuum tank switch kit is made of high-quality plastic that was developed to provide steady performance and reliability for years to come.
How It Works When a vacuum is being created in the tank by the vacuum pump the diaphragm on the switch gets pulled in - once the tank reaches 8-10 inches the spring on the diaphragm is pulled in enough to release the snap action switch on the end of the assembly, turning your pump off. Once your vacuum is released from the system by flushing your toilet, the spring is released, activating your snap action switch, and turning your pump on to create the vacuum lost.
