RootRain Hydrovent

The Hydrovent irrigation system (RRHYDR1A) comprises of a cast aluminium (LM6) inlet with an anodised aluminium (5083) lid. The lid is connected to the inlet with a non-removable stainless steel nyloc fixing which allows the lid to lift and swing to one side if required.

The inlet is 120 mm diameter and 40 mm deep. The overall width reduces down to 72 mm externally with a ribbed internal face to accept the push fit connection of 60 mm perforated pipe. The inlet has 2No protruding lugs on opposite sides which secures the inlet firmly into place when used with GreenBlue Urban tree grilles. 

This design is an anti-vandal deterrent and ensures that the inlet stays flush with tree surround into which it is fitted. The system is supplied with 3 linear meters of 60 mm pipe and 1No 60 mm ‘tee’ fittings.  

The Hydrovent system is supplied in kit form for installation on site. The correct installation comprises of a ring of pipe positioned horizontally around the root ball of the tree, about a third of the way down the root ball and connected using the tee pieces to the vertical riser and terminating with the aluminium inlet which will fit flush with the immediate tree surround. Irrigation of a tree via a Hydrogrille will ensure no water is wasted and the water is delivered to exactly where the tree needs it.
