Before you book

Questions worth asking a manufacturer:

  1. Rated output and draw at 25 °C seawater, and how much both fall in cold or silty water.
  2. Pump architecture: conventional high-pressure pump, or energy recovery? It sets the Wh/L.
  3. Whether membranes, prefilters and fittings are standard sizes you can buy anywhere.
  4. What happens when a proprietary controller fails, and what a swap costs.

Not sure what size you need? Run the sizing calculator with your crew and battery bank before you ring.
