This kit allows large water volumes to be stored by interconecting multiple tanks together. Storage capacity is only limited by the area available for tank installation. The system uses camlok fitting for fast and secure connection.

Ecov DN150 threaded tank adapter for DWV SW pipe and fittings.  The adapter incorporates a tool connect fitting design and includes one standard screw-cap flat washer and a 10 mm round x 158 mm diameter rubber O'ring for secondary sealing.

The use of this assembly avoids cuting into the side wall of a polyethylene or other tank causing a change in the structurial integrity of the tank and its ground loading effect on its design safety factor.
