The pressure sensor (flow switch) on most AquaCal pool heaters is typically located on the water inlet plumbing, near where the water enters the heat pump unit. It is often a small device with wires connected to it, mounted either directly on the plumbing manifold or close to the filter/pump side. Refer to your specific AquaCal model’s manual for the exact location, as it may vary slightly by model.
