Our Mini Softener Unit can be placed over the small water pipe behind the fridge that feeds your ice maker, the pipe beneath the sink that goes to your dishwasher, the water pipe in the back of the toilet, a small water feature, or any other low flow pipe you would like to boost. The installation of this unit can assure freshly treated water goes into the device. If you have a commercial coffee machine with it's own water line, it can also use one of these. And they can fit in small places!
