Rola-Chem 550311 Interlock Pressure Switch Kit, 1-6 PSI
Rola-Chem 550311 Interlock Pressure Switch Kit, 1–6 PSI is an essential safety component engineered to protect swimming pool and spa chemical injection systems from accidental overfeeding and unnecessary chemical exposure. Designed to activate the connected 120V pigtail only when active water pressure is detected, the switch ensures that chemical controllers and injection pumps operate exclusively during circulation. This advanced safeguard eliminates chemical feed during system shutdowns, reinforcing a safer and more controlled dosing environment.
With an adjustable pressure range of 1 to 6 PSI and a factory preset of 3 PSI, the kit delivers dependable performance tailored to a wide variety of hydraulic conditions. Precision responsiveness helps maintain proper synchronization between water flow and chemical injection, significantly improving dosing accuracy and overall system efficiency. This makes the switch especially valuable in residential, commercial, and aquatic facility applications where safety and water balance are high priorities.
Built to be compact yet durable, the Rola-Chem 550311 kit includes all necessary components for a complete installation: pressure switch, enclosure box, tubing, and fittings. Each element is engineered to work cohesively for a straightforward setup, minimizing downtime and ensuring proper system integration. Once in place, the unit provides long-term reliability through consistent pressure detection and secure electrical operation, even under demanding usage conditions.
