CAN THE QWIK JON TANK BE INSTALLED BELOW GROUND?
This is not recommended unless you have a very low ceiling to contend with. The tank can be hidden from view by building a floor over the tank. If the concrete floor has not been laid yet, install a typical in-ground basin, which is also available from Zoeller. If the tank is installed below ground; allow for the expansion and contraction of the tank (1/4″ on each side), sit the tank on a solid level concrete slab capable of supporting the weight, and do not install in such a way that you limit your access to the tank.
