Why Buy From Us

Maintaining accurate hydraulic feedback is critical for the safe operation of your pool heating system, and the PRS3406 water pressure switch acts as the primary safety interlock for Lochinvar EnergyRite ER(N, L) 152-402 units. By confirming adequate water flow before ignition, this switch prevents overheating and protects internal heat exchangers from potential damage.
This component utilizes a diaphragm-activated electrical contact that closes a circuit once the internal plumbing reaches the minimum necessary operating pressure. When flow drops below threshold levels, the switch instantly breaks the circuit, effectively disabling the heater to safeguard against dry firing and excessive thermal stress.
Key System Performance Baselines:
- Safety Interlock: Prevents burner ignition during low-flow or no-flow conditions.
- Pressure Sensitivity: Calibrated specifically to match the hydraulic requirements of EnergyRite residential models.
- Reliable Switching: Features a responsive design that triggers rapid response to changes in system head pressure.
⚠️ Application Profile: Specifically engineered for residential pool and spa heating environments using Lochinvar EnergyRite (ER/EN/EL) 152 through 402 series units.
