PRO SILVER SERIES FEATURES
The patent pending Dual-Flow™ fittings are an oversized 50mm for a more free flowing system. These fittings are over 3x the internal size of the 32mm. They enable the water to pass through slots located on the sides of the fitting, allowing total drainage of the pot.
Heat-reflective silver 50mm pipe is used vs the Black Series green 32mm.
The pots and lids are also produced from heat-reflective silver polymer.
The Silver Series feature copper plated drain covers which deter the roots from entering the pipework.
