Caixa d'água is the Brazilian name for a motorhome or trailer fresh-water tank. Typical capacities on Brazilian models: 80–250 L. Food-grade polyethylene is standard.
Refill at filling stations with a potable-water tap, at camping de apoio, or from bottled-water vendors. Best practice: sanitise once a season with hypochlorite (1 mL per 10 L), drain before long storage, fit an in-line filter at the inlet. Level sensors on premium Brazilian models (Karman, Trinkle, Mantra) with a CBE/Nordelettronica panel.
