WHO IS THIS KIT FOR? - Ideal for larger or more complex campervan and motorhome hot and cold water systems, providing a wider range of John Guest 12mm connectors for multiple outlets and more extensive plumbing layouts.
 
 
 
Build a complete hot and cold campervan water system for a kitchen sink, internal shower and water heater using John Guest 12mm plumbing.
 
 
 
The Advanced Hot & Cold Water Connector Kit brings together the pipe, isolation valves and push-fit fittings needed to create a larger pressurised campervan water system without sourcing every component individually.
 
 
 
Designed for installations with one kitchen sink, one shower and one hot water heater, with selectable connections for each appliance.
 
 
 
💧 WHY WE USE THIS KIT
 
Adding a shower to a campervan water system means more pipe runs, branches, valves and fittings.
 
 
 
This kit provides the core components for a practical hot and cold installation, with additional isolation and enough fittings for routing pipework throughout the vehicle.
