IWS Copper Insert
The IWS Copper Insert is a solid copper fitting for the IWS Flood and Drain systems. These parts fit snugly inside either an IWS Tee or IWS Elbow on the inside of your IWS outer pot. They measure 16mm (13mm internal) x 62mm.
What do IWS Copper Inserts do?
The IWS Copper Insert creates a natural barrier against your plants growing their roots into the IWS Tee or IWS Elbow and preventing blockages in your system. Plant roots hate copper!
