"Website details were accurate. As stated, it is very compact and should fit many under-sink cupboards. It comes with a useful set of connectors and the hardness test kit needed to set it up. Installation was a straightforward D.I.Y. task. Being a metered unit, it should prove more economical than unmetered softeners. Flexible hoses supplied would enable it to be connected and then pushed right back in to its planned location, except that the overflow is conventional rigid overflow pipe. I strongly recommend reading the full online manual in advance of D.I.Y. installation as there are several points to consider:, including the fully loaded weight; the need to check the water pressure before installation; and the positions of the overflow and drain. The great majority of the construction is in plastic, so corrosion should be minimised. I can't comment long term reliability information as yet, and it is noticeable that the manufacturer only offers a 1-year warranty on this model"
