Just been out to look at an old Euro water softener. No soft water and the motor was solid. The customer had paid for a new servo on the last service but broken again. On closer inspection the resin was worn out and had turned in to jelly. The previous engineers solution was to open the bypass giving the cutomer hard water anyway. Marked sinks and dirty showers soon followed.
Our solution. Replace the unit with a quality English made block salt water softener. No electricity and easy to load with salt.
happy softener happy customer.
