| Ensign Water Softener |
Non-electric water softening process. Metered water with 12volt electronics
to keep the time, count the litres used and control the salt low monitor only. That costs about
21p a month. No power is used to soften water |
| Block Salt Water Softener |
Non-electric water softening process. Metered water with mechanical
control and no salt monitor. Powered by running water down the drain. Customer is obliged into expensive brand loyalty by a rather
unfair claim that their warranty may be voided by the use of any other brand
of salt that is not theirs.
