WHO IS THIS KIT FOR? - Ideal for campervan and motorhome builds where you need a simple, reliable way to connect your water pump and accumulator tank to a 12mm John Guest water system.
 
Connect your campervan water pump and accumulator with a complete set of John Guest 12mm fittings.
 
This connector kit is designed for campervan and motorhome water systems where you already have your pump, filter and accumulator tank but need the correct fittings to connect the system together.
 
Based on the same connection setup used in our complete pump and accumulator bundle, it provides the essential pipe, valves, adapters and securing components in one convenient kit.
 
💧 WHY WE USE THIS KIT
Connecting a pump system requires several small fittings that are easy to overlook when ordering components individually.
 
This kit brings the core connections together in one package, making it easier to build a clean and serviceable 12mm pressurised water system.
