ABSTRACT:
A tank tee unit is formed from a plurality of standard pvc pipes secured together only by a suitable glue. It includes a main pipe of heavy wall pvc sandwiched between and glued to two heavy wall pvc pipes extending perpendicularly therefrom which are in turn each glued to a standard smaller diameter pvc pipe that passes entirely through the main pipe to form an extremely strong joint. This provides a unit in the form of a cross with outlets on opposite sides of the main pipe and with thick wall branch lines that can be tapped for other side connections. One side outlet can be plugged to provide a strictly tee unit.
