What this video covers

The crew of the 45-ft former fishing trawler Brupeg installs a custom watermaker system, utilizing a Karcher K4 pressure washer as the high-pressure pump to drive a reverse osmosis membrane.5:54 The installation requires a multi-stage filtration sequence: a 50-micron stainless mesh intake filter, followed by 20-micron and 5-micron sediment filters.4:42 The system incorporates a back-flushing circuit that uses pressurized freshwater to clear the membrane after use, preventing salt buildup.6:47 To save space, the crew strips the Karcher K4 housing of unnecessary plastic, wheels, and handles.9:26 They mount the unit to a bulkhead using a combination of U-bolts through the top handle and a welded axle bracket at the base to ensure a robust, vibration-resistant fit.27:14 The plumbing layout prioritizes gravity-fed flow below the waterline and includes one-way valves to isolate the seawater intake from the freshwater flushing system.21:45 The project emphasizes accessibility for filter changes and the need to protect electrical components from potential leaks.2:32
