Top Fill Configuration Rainwater Tanks

Rainwater bladder tanks with a top fill option has the inlet on top of the bladder. The downpipe is required to be connected to the inlet through a flexible pipe extension. This flexible pipe extension will be supplied with the bladder, to avoid stressing the inlet connection point when the bladder is being filled or emptied frequently. This increases the bladder’s durability and longevity. Furthermore, the flexible pipes also allow for more installation dimension tolerances. The outlet is placed at the side, closer to the bottom to maximise the water extraction from the bladder.

The inlet fitting can be either 90mm or 100mm and the outlet fitting can either be 32mm or 25mm as standard. A flexible outlet piping section will be supplied to eliminate the vibration of the pump passing into the bladder tank. This arrangement is ideal when you have hard ground or concrete slabs which cannot be dug for underground piping.
