Dahlberg: Marine Sanitation Experts Since 1989
One of the most important, yet often overlooked, aspects of boat maintenance is the sanitation system: toilets, black and gray water tanks, sensors, and hoses. Poor maintenance can lead to unpleasant odors, blockages, and breakdowns, which can ruin any trip out on the water.
What does good maintenance entail?
-
Disinfect and descale sanitary systems to remove waste and paper residue.
-
Check hose connections for leaks.
-
Thoroughly clean tanks and sensors.
-
Use specific products that extend the useful life of the equipment.
Proper winterization is the best way to keep your equipment in perfect condition, extend the life of consumables, and save money on future repairs.
Since 1989, we at Dahlberg have been pioneers in marine sanitation. Starting with Seeland vacuum systems, now DOMETIC, we've established ourselves as the best place to trust your boat's sanitary maintenance.
One of the pillars of this trajectory is Antonio Lopera Ortiz, or simply Toni, our Technical Director. With nearly four decades of experience, Toni has been an essential part of the company's technical development. His in-depth knowledge of navigation systems, marine instrumentation, and, especially, DOMETIC vacuum sanitation products, makes him an undisputed leader in the sector.
Their role encompasses everything: technical support, training, consulting, diagnostics, installation, and continuous improvement. Their ability to solve complex problems, train new technicians, and maintain a focus on quality make their work irreplaceable.
