Jabsco 12V Black Treatment System Relay Box

The Jabsco 12V Black Treatment System Relay Box is a replacement electrical control component for compatible Jabsco 12V 38XXX-series waste-treatment systems. It is intended to restore or service the relay-control function within the supported sanitation system rather than operate as a standalone pump or treatment device.

Using the correct relay box helps preserve the electrical switching arrangement designed for the original waste-management system. Because this component is series-specific, matching the existing Jabsco system designation and 12V electrical architecture is essential before replacement.

Verify the complete treatment-system model, supply voltage, wiring connections, and existing relay-box part requirements before ordering. Disconnect electrical power before service, label wiring before removal, follow Jabsco installation instructions, and test the complete treatment system after replacement. Take a look through our bilge and water pumps.
