💧 WHY WE USE THIS WATER PRESSURE KIT
We use this Seaflo 12V pump + accumulator combination in our own campervan conversions to achieve stable water pressure with reduced noise and pump cycling.
 
Adding an accumulator tank makes a noticeable difference in everyday use — taps feel smoother, the pump runs less often, and the overall system is quieter and more reliable.
 
This kit is ideal if you want a professional-feeling water system, not just a basic on/off pump setup.
 
✅ SUITABLE FOR
• Campervan and motorhome fresh water systems
• Vans with sink and/or shower setups
• Off-grid 12V pressurised water systems
• New builds or upgrades to existing pump-only systems
 
❌ NOT SUITABLE FOR
• Very large systems with multiple simultaneous showers
• High-flow commercial or continuous-use applications
• Systems using non-standard pipe sizes
 
🚐 REAL-WORLD USE
This exact pump and accumulator setup is used in our Fiat Ducato campervan conversion as part of the fresh water system.
