  • Four ports for separate fertilisers
  • Check valves stop backflow
  • Aluminium body that won't corrode

Fertiliser goes into the filter hose instead of straight into the tank, so it leaves the outflow already mixed rather than pooling in one corner. Four ports with check valves let a dosing pump feed several liquids into a 12/16 mm line without backflow.
