The electric pump module directs gasthrough the check valve into the connector to increase the gas pressure in the tank andforce the liquid in the tank to flow through the feed line and out the spray nozzle. Theswitch assembly turns off the electric pump when the gas pressure in the tank exceeds apredetermined limit while maintaining the flow of liquid through the spray nozzle.
