Questions worth asking a manufacturer:
- Rated output and draw at 25 °C seawater, and how much both fall in cold or silty water.
- Pump architecture: conventional high-pressure pump, or energy recovery? It sets the Wh/L.
- Whether membranes, prefilters and fittings are standard sizes you can buy anywhere.
- 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.
