Van Water System Kits

Van Water System Kits deliver running water without the leaks and guesswork of piecing parts together yourself. Each kit includes a fresh water tank, a grey water tank, a Shurflo or Seaflo demand pump, an accumulator, food-grade PEX or hose, fittings, and a tank-level monitor. We offer compact 12-gallon setups for weekenders and 40-gallon-plus systems for full-timers who want longer stretches between fills. Most builds run from about $650 for a basic gravity-fed kit to around $2,400 for a pressurized system with hot water pre-plumbing. Tanks are shaped to tuck under beds or into cabinets in Sprinter, Transit, ProMaster, Express, Savana, and Rivian platforms.
