| Fresh-water flush after use | every use, per maker operating procedure |
|---|---|
| Pickling/preservation before layup | before any period of disuse beyond the maker's stated limit, typically a few weeks |
| Clark Pump seal/rebuild kit service | commonly in the order of 1,000-2,000 hours or a few seasons of typical use - confirm against current Spectra/Katadyn service literature |
| Pre-filter element renewal | per differential pressure/fouling trend, commonly every 1-3 months in service |
| Product flow drop from commissioning baseline | a drop beyond roughly 10-15% from the baseline commissioning flow at similar feed conditions is commonly used as a trigger for internal inspection - treat as a general guide, not a maker limit |

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Note: the Clark Pump is the energy-recovery high-pressure pump element within a complete Spectra reverse-osmosis watermaker system, not a standalone freshwater generator - the notes above concern this pump specifically. Class treatment of freshwater generation equipment is normally limited to potable water system hygiene/certification unless the vessel's class notation specifically covers the fresh water system.
Estimated lifetime: Rebuild kits are commonly specified on a multi-year or roughly 1,000-2,000 hour cycle depending on usage and water quality; the pressure vessel/rotating group itself commonly outlasts several rebuild cycles with proper maintenance - treat any figure as a planning guide only.
