Build a fully capable, expandable campervan water system designed for daily use, hot water integration, and multiple outlets.
 
The Advanced Van Plumbing Kit is engineered for serious van conversions where reliability, serviceability, and long-term performance matter.
 
Designed around genuine Seaflo components and a complete 12mm John Guest push-fit plumbing system, this kit provides everything required to install a clean, modular, and professional-grade freshwater setup.
 
If you’re building a van with a sink, shower, and water heater - this is the correct foundation.
 
🔧 Why We Use This Advanced Kit
This configuration is used in our own campervan conversions where higher water demand and system flexibility are required.
 
It’s designed for:
• Multiple water outlets
• Internal shower installations
• Hot water heater integration
• Higher daily water usage
• Long-term serviceability
 
The additional pipe runs and isolation valves allow you to section off parts of the system for maintenance - a key feature often missing in basic campervan plumbing kits.
 
This is not a simple sink setup.
This is a structured, expandable van conversion water system.
 
✅ Suitable For
• Advanced campervan and motorhome water systems
• Vans with sink and internal shower setups
• Builds integrating gas or electric water heaters
• Off-grid and full-time vanlife installations
• DIY builders wanting a professional-grade plumbing layout
• Systems requiring multiple outlets and isolation points
 
❌ Not Suitable For
• Basic single-sink camper setups
• Ultra-minimal or temporary water systems
• Builds without space for proper pipe routing
• Very high-flow commercial applications
 
🚐 Real-World Use
This kit reflects real van conversion installations - including internal sink and shower systems with hot water supply and dedicated isolation valves for servicing.
The layout structure mirrors modern camper builds where clean routing, accessibility, and long-term reliability are priorities.
It allows you to build once - and build properly.
