Rated 5 out of 5 by from Fabulous little softener We opted for a smaller water softener due to lack of cupboard space in the kitchen so thought we'd give this one a try and were certainly not disappointed. The quality of the unit is very good, unlike some flimsy plastic ones of a similar price. Being a metered unit means that it's economical to run (It's been installed for around 5 months and we're still on the same bag of salt). We tested the softness of the water following installation (using the supplied kit) and the softness was spot on - despite the hardness of the water in our area. We also have a 3 toilets (WC, ensuite and main bathroom) and even though this is small it is more than adequate to supply water around the house, as well as the dishwasher and washing machines working simultaneously. We didn't install the softener ourselves, rather getting a local water softener company in (who usually supply the £0000 units) and he had no grumbles with any of the fittings etc.

Rated 3 out of 5 by from Early days yet I installed the water softener myself, in an under-stairs cupboard where the incoming water main is located. Installation was straightforward apart from a couple of issues: firstly the 15mm kit contained the wrong valves - inline valves were supplied instead of T-valves and I had to go and purchase a couple of 15mm Tees. Secondly there is a mistake in the installation instructions, where item 9 reads "Check that the Brine Cabinet contains salt and water". I had to telephone the manufacturer's technical helpline and they advised that this is a misprint and in fact the brine cabinet should only contain salt at this stage. My final problem was that this model is designed to work with tablet salt, not block salt, however Screwfix only stock the latter and so that is what I ordered, not knowing at that stage that there is an important difference. The softener itself is not supplied with any salt and Screwfix should probably make this clear in their description, along with advice as to what type of salt is required. My three star ratings for performance and reliability should be ignored, as it is too early to judge these criteria at the moment. I will update this review after using the product for a month or so.

Rated 4 out of 5 by from Easy D.I.Y. install. 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
