Looked at some photos I took when I installed the unit and it appears to be working quite well.
The new shower head I installed just before I installed the SofterWater Conditioner has not deteriorated like they normally do, also the outdoor taps which I cleaned at the install no longer have a build up of soda etc. on them.
In the garden the water appears to penetrate the soil much better as I dug a few postholes last week and had no trouble digging down over 600mm. Prior to the install of SofterWater Conditioner the water never penetrated the soil and formed a hard crust on the surface and digging postholes would be quite difficult.
