Tile Drain
Two tile drain assemblies are supplied for demonstration of dewatering using the tile
drain technique. The tile drains can be used independently or in combination as
required.
Tile Drain
Each drain consists of an 8mm internal diameter copper tube, with one end closed
and having a pattern of eighteen holes drilled along its 150mm length. The open end
is connected to a clean PVC tube 500mm long. Fine woven material is fastened
around the copper tube to act as a filter.
These tile drains can be screwed into any of the six tappings in the aluminium plate
at the rear of the tank, having removed the appropriate sealing plug. Each tapping
incorporates a screwed plug to seal the tapping when no tile drain is fitted.
