Real-World Testing: Putting Johnson Pump Grey Water System, 1000GPH, 24V to the Test

My testing grounds for this grey water system were twofold: initially, on the workshop bench to verify connections and operation, and then, more importantly, aboard my own vessel during a couple of extended weekend cruises. This involved simulating typical grey water generation from showers, the galley sink, and even a small dishwasher setup integrated for testing purposes. The aim was to see how it performed under varying loads and continuous operation, particularly during periods of heavy use when multiple sources were draining simultaneously.

First-time use was surprisingly straightforward. The system’s automatic Ultima switch technology meant that once wired correctly, it handled the water without any manual intervention. There were no immediate quirks or unexpected issues, which is always a good sign in marine gear where simplicity and reliability are key. The multiple inlet ports were particularly useful, allowing me to plumb the shower drain, galley sink, and even a small utility sink into a single, efficient collection and discharge point.

After several weeks of consistent use, encompassing around ten trips and daily operation when the boat was occupied, the Johnson Pump Grey Water System, 1000GPH, 24V has held up remarkably well. I’ve encountered no signs of wear and tear on the housing, and more importantly, no leaks or performance degradation from the pump itself.
